What is pyrolysis machine? What raw material can be recycled by pyrolysis machine?

Pyrolysis machine, also called pyrolysis plant/pyrolysis unit/pyrolysis device, is a popular waste treatment recycling machine that can recycle and convert solid&hazardous waste like rubber tires, scrap plastic, oil sludge, biomass, coal tar oil residue, aluminum plastic composite materials, plastic medical waste, e-waste(like PCB), etc. into valuable products namely pyrolysis oil, syn-gas and char(carbon black), biochar, aluminum ingot, etc.

1. Q: What are the key components of pyrolysis machine?

A: The key components of DOING Pyrolysis Plant are as follows:

①Waste Pre-teatment system: such as waste tyre shredder, rubber tires cutting machine, scrap plastic grinding machine, biomass wood crushing machine, biomass pellet machine, etc.

②Waste Feeding system: different feeding systems, we support munual feeding, auto-feeder and continuous feeding ways.

③Pyrolysis reactor system: made of different boiler plate and other 304/3016 steel materials, the thickness of pyrolysis reactor can be customized from 14-22mm. And the inner structure of DOING pyrolysis reactors may have different designs, for example, for oil sludge thermal pyrolysi streatment, we have anti-coking devices for reaction vessels.For example, for sludge treatment, we have anti-coking devices for reaction tanks.

④Oil gas condensation system: there are both multiple-stage shell tube condensation systems and waste tank condensation systems to choose from, both of them has good oil cooling effect to ensure high oil yield.

⑤Pyrolysis residue discharge system: We are equipped with different unloading equipment for different pyrolysis products, such as carbon black lifting devices, carbon black sealing systems, wire drawing equipment, etc.
⑥Exhausted gas purification system: DOING pyrolysis machine is equipped with exhaust gas purification devices, desulfurization and denitrification towers and dust removal devices to ensure the control of particulate matter, sulfur dioxide, nitrogen oxides, and volatile organic compounds, and to guarantee strict compliance with emission standards, even those of European Union countries;

2. Q: What is the common/typical output of pyrolysis machine?

A: The output depends largely on inputs in terms of quality and types of waste raw materials and the pyrolysis technology which has been used to process the waste. The final products outputs of pyrolysis plant are mainly:

The output rate and applications of final products from pyrolysis machine

①Pyrolysis Oil ≈ 30 to 85%

(The tire pyrolysis oil yield is about 35-52%，the plastic pyrolysis oil output is between 30% and 95%.)

Pyrolysis oil is an important liquid product generated during the waste pyrolysis process, with a calorific value typically ranging from 42000 to 46000 kilojoules per kilogram, which is close to or exceeds the calorific value of some traditional fuels. pyrolysis oil can serve as an efficient energy substitute and is widely used in the industrial sector, especially for the combustion of heavy oil power plant, boilers, or heating furnaces. 
Compared to conventional fossil fuels, cracked oil has lower production costs and, due to its source from waste, the production process can effectively reduce carbon emissions, which meets current environmental policy requirements. In the chemical industry, pyrolysis oil can be further converted into various chemicals as raw materials, or used as raw materials for heavy oil /waste oil refineries to extract higher quality fuel resources, such as non-standard diesel, thereby further improving the economic benefits of waste pyrolysis projects.

②Pyrolysis gas ≈ 17 to 35%

Pyrolysis gas (mainly composed of methane, ethylene, propylene, etc.) has a high combustion heat value. Its advantage is that pyrolysis gas can be recycled for heating reaction vessels, replacing external energy supply, thereby significantly reducing the energy cost of pyrolysis plant projects. Through this approach, not only has energy efficiency been improved, but also a significant amount of operating costs have been saved for the enterprise. 

③Pyrolysis residue, mainly carbon black ≈ 3 to 25%

(The content may increase when there is ash content in the feedstock.)

Carbon black is an important solid product in the pyrolysis process, and its unique conductivity, wear resistance, and reinforcement properties make it widely used in various industries. Especially in the rubber industry, carbon black can improve the wear resistance and aging resistance of tires, and improve the service life of products. In the plastic, ink, and coating industries, carbon black can enhance the coloring power and weather resistance of products, and is widely used in fields such as automotive, electronics, and building materials. With the continuous improvement of global environmental requirements, the market demand for carbon black continues to grow, and its high added value makes it an important source of profit in waste pyrolysis projects.

④Charcoal/Biochar ≈ 30 to 35%

Charcoal/Biochar is a carbon based material obtained by pyrolysis agricultural and forest waste such as wood, bamboo, coconut shells, and rice bran. It has significant carbon fixation capacity and can convert these biomass wastes into stable carbon assets, effectively reducing carbon footprint. In agriculture, biochar can improve soil structure, enhance soil water retention, permeability, and fertility, increase crop yield and drought resistance, and is an environmentally friendly soil amendment. In addition, the use of biochar also has a significant carbon sink effect, reducing carbon dioxide emissions through long-term carbon storage, and is an important means of addressing climate change. 

With the promotion of the concept of green and sustainable development, the application of biochar in agriculture, horticulture, wastewater treatment, and air purification has gradually expanded, becoming an indispensable green product in biomass wastes pyrolysis projects.
