A reddit for news on research projects into pyrolysis as a method of producing a usable fuel

The Pyrolysis Reddit

Pyrolysis is a thermochemical decomposition of organic material at elevated temperatures in the absence of oxygen. It involves the simultaneous change of chemical composition and physical phase, and is irreversible. The word is coined from the Greek-derived elements pyro "fire" and lysis "separating".

Pyrolysis is a type of thermolysis, and is most commonly observed in organic materials exposed to high temperatures. It is one of the processes involved in charring wood, starting at 200–300 °C (390–570 °F). It also occurs in fires where solid fuels are burning or when vegetation comes into contact with lava in volcanic eruptions. In general, pyrolysis of organic substances produces gas and liquid products and leaves a solid residue richer in carbon content, char. Extreme pyrolysis, which leaves mostly carbon as the residue, is called carbonization.

The process is used heavily in the chemical industry, for example, to produce charcoal, activated carbon, methanol, and other chemicals from wood, to convert ethylene dichloride into vinyl chloride to make PVC, to produce coke from coal, to convert biomass into syngas and biochar, to turn waste into safely disposable substances, and for transforming medium-weight hydrocarbons from oil into lighter ones like gasoline. These specialized uses of pyrolysis may be called various names, such as dry distillation, destructive distillation, or cracking.

Diy solar pyrolysis reactor: How much temperature do I need for do pyrolisis on weeds

In my garden I have too many weeds, therefore I thought to setup a test apparatus so I can make a proof-of-concept mini solar pyrolysis reactor.

I thought to buy this lens, and use a sealed iron pipe as reaction chamber.

Also, the reaction chamber will be placed longtitunally but because it is a pipe I am afraid that air will come inside the chamber. The initial idea is:


The idea is that I let the fresnel lenz to blast yje pipe with sun rays to sealed pipe and once gas is formed I'll open the sealing valve so the syngas to be released.

The questions are:

  1. What is the minimum temperature for the pyrolysis reaction to happen?
  2. Is there a better way to seal the pipe without using the tap? For pyrolysis to happen I need no oxygen in the pipe (that is my reaction chamber).

What is the cost of tyre pyrolysis plant?

There are many people pay attention to this problem. Today this article is mainly for everyone to solve the doubts of this problem.

The cost of tyre pyrolysis plant cannot be just from the price of tyre pyrolysis plant. It is composed of several parts: raw material cost, land cost, operating cost, equipment cost.

Cost of tyre pyrolysis plant

  1. Raw material cost

The cost of raw materials refers to the price of waste tyres. The price of waste tires in different regions is different, so before investing, it is recommended to check the price of waste tires on the local market.

  1. Land cost

When you want to invest in this equipment, you can choose to rent or buy land, you can build a complete workshop, or you can just build a simple steel structure roof, which is determined according to the your budget.

  1. Operating cost

One unit tyre pyrolysis plant needs 2-3 workers to operate, power consumption is 20 kw/h. In addition to the exhaust gas can be used to heat the machine which will save more than half of the fuel, but every day need an additional 500 kg of fuel oil as a fuel, generally customers use the produced tyre oil as fuel, don't have to go to the market to buy fuel, if the price of local natural gas or coal is cheaper than fuel oil, then you can also choose natural gas or coal as fuel. Tyre pyrolysis plant uses recycling water for cooling, so almost no consumption.

  1. Equipment cost

The equipment cost includes the price of basic configuration and optional configuration. A set of basic configuration of tyre pyrolysis plant is a production line for producing tire oil. However, in recent years, more and more countries have paid attention to environmental protection, so our company is constantly development design some optional environmental protection configurations, such as exhaust gas deodorization device, carbon black collection device, dust removal device, etc., as well as safety devices and automation devices, such as negative pressure system and automatic feeding machine, which can ensure the safety of equipment operation and save labor. Therefore, the basic configuration plus different optional configurations will have different prices. The higher the configuration, the higher the price, which is also determined according to the customer's budget. Some countries or regions where environmental protection is not strict and labor is cheap can choose low-configuration tyre pyrolysis plant. Some countries with high environmental protection and high labor cost are recommended to choose high-configuration tyre pyrolysis plant.

High-configuration parts of tyre pyrolysis plant

Through my introduction, I believe that you probably know how to calculate the cost of making tyre pyrolysis plant. From these several parts, some parts need to do the local market investigation, some parts need to consult tyre pyrolysis plant manufacturers to obtain a better suggestion. When investigating the market, you also need to investigate the market price and sales of by products, such as tire oil, carbon black and steel wire, so that you can calculate your own profit according to the cost of tyre pyrolysis machine and the sales price of the by product, then you will make a clear decision whether to make tyre pyrolysis plant.

I hope this article can help you who are confused about the cost of making tyre pyrolysis plant. If you want to know more, please contact us.

Hello folks. Im new here cause I gotta make a research paper. I have a question... What is pyrolysis and who made the definition? Is melting plastic NOT to the degree of making oil but just melting to soften it like a bubblegum considered as pyrolysis? Pyrolysis just states that heating with no direct contact to fire. I'd like to get any idea. Sorry im new here and im just stupid.

Will it be more profitable to buy second hand waste tire pyrolysis plant?

Many business men will consider one question before starting their waste tire recycling business- to buy new waste tire pyrolysis plant or the second hand pyrolysis plant. After all, compared with the new pyrolysis plant, the second hand waste tire pyrolysis plant is much cheaper than the new one.

Second hand waste tire pyrolysis plant and the new pyrolysis plant

We Doing Group as an experienced manufacturer of waste tire pyrolysis plant would like to suggest you to buy the new waste tire pyrolysis plant because the second hand waste tire pyrolysis plant will not bring you more profits than the new. I’ll explain why in the following part.

  1. Quality problems and short service life

Generally, the waste tire pyrolysis plant will not be sold in a low price without any problems and its owner has a great possibility not tell you the problems in order to sell it smoothly. If you don’t know the waste tire pyrolysis plant well, you will not find its problems which may have some potential dangers. Besides, the second hand waste tire pyrolysis plant has a short service life compared with the new one which means you need to buy the waste tire pyrolysis plant again in a short term.

In addition, the oil yield rate of second hand waste tire pyrolysis plant is relatively low which means you need to buy more raw materials to the same amount of fuel oil. So buy the second hand waste tire pyrolysis plant, your subsequent investment will be greater .

  1. No after-sales service

The second hand waste tire pyrolysis plant is not usually purchased from the professional waste tire pyrolysis plant manufacturer, so there will be no engineers to help you install the pyrolysis plant and train the workers. You need to find professional engineers to do it alone which is a time-consuming and costly thing.

Beyond that, there is no technical support at all if you have any operation problems. Fixing the problems of second hand waste tire pyrolysis plant also needs a lot of money.

Therefore, we do suggest you to buy the new waste tire pyrolysis plant because the second one will not bring you more profits. If you want to do the waste tire recycling business, welcome to call us, our product manager can give you a lot of advice according their experience.

How much is pyrolysis plant? What are the factors that affect the price?

More and more investors want to get into the pyrolysis business, and when they do, most want to know how much is pyrolysis plant. Because of the fierce competition in the market, each manufacturer keeps the price of the pyrolysis plant secret. So it is difficult for you to know many quotations. By knowing the following introduction, you can know whether the pyrolysis plant price you get is reasonable and then choose a suitable pyrolysis plant manufacturer.

Based on the rich experience of DOING company in the past 10 years, we know that the price of pyrolysis plant is mainly affected by factors such as, pyrolysis plant manufacturing materials, configuration, capacity, type, manufacturing process, etc.

  1. Pyrolysis plant configuration

Just like cars, highly configured cars enjoy better comfort and satisfaction. And the pyrolysis plant also has high configuration and low configuration. High-configuration pyrolysis plant will have high oil yield and environmental protection capacity. If you have high expectations for pyrolysis plant, you will have to choose a high configuration, but also to accept a slightly higher price. You may have heard of lower prices of pyrolysis plant from some pyrolysis plant manufacturer, but have you looked at the specific configurations? The same configuration of pyrolysis plant, the price is comparable.

Full set pyrolysis plant with high-configuration

  1. Type of pyrolysis plant

At present, pyrolysis plant can be divided into two types according to the degree of automation: full continuous pyrolysis plant and batch pyrolysis plant. Full continuous pyrolysis plant with high degree of automation, PLC control system, can achieve continuous feeding, continuous slag production. Batch pyrolysis plant requires batch processing of raw materials, leaving time for reactor cooling and slag discharge operations. Obviously, the utilization rate of intermittent pyrolysis plant is not as high as that of continuous pyrolysis plant, and the price of different types of pyrolysis plant is also different. In the batch type, there is also a small pyrolysis plant that can be used to test the oil yield of the raw material. The cost of small pyrolysis plant is low, and some investors buy them to do early-stage project testing.

Three types of pyrolysis plant

  1. Pyrolysis plant reactor manufacturing process

Pyrolysis plant belongs to a full set of production equipment. In the manufacturing process will involve a lot of parts of the welding, just welding there are two forms of ordinary welding and smooth welding, and the use of smooth welding requires higher skills. The arc head pyrolysis reactor welded by smooth welding method is not easy to separate the furnace body, can withstand high temperature and high pressure, and extend the service life of pyrolysis plant. Therefore, the pyrolysis plant made by this welding process will be more expensive.

In addition to the above factors, the price of pyrolysis plant will also be affected by oil price, market environment and other factors, but combined with the above main factors, you can determine whether the price of pyrolysis plant manufacturers is reasonable, and then buy pyrolysis plant at the right price.
