Pyrolysis consists of a endothermic reaction. General combustion occurs through the generation of heat in the Pyrolysis chamber producing solids and liquids. The feedstock is heated at moderately high temperatures in a low oxygen atmosphere.
Pyrolysis Oil Diesel produced by this pyrolysis process can be used purely as a fuel if refined further or for other related end products & chemicals. The syngas produced in used for the pyrolysis combustion process and to run the power generation turbine(s) or be reformed into green Hydrogen.
The biomass used in pyrolysis is typically composed of cellulose, hemi-cellulose and lignin. The main parameters that govern the pyrolysis process are temperature, heating rate, solid residence time, volatile residence time, particle size and density of particles.
The products produced in the process vary and depend on the feedstock type. Ie: cellulose material and some biomass produce biochar and activated carbon. Mixed Residual Waste (MRW) and Municipal Solid Waste (MSW) feedstocks product Pyrolysis Oil Diesel, Hydrogen and Electricity and a small amount (10% of weight) of inert ash.
MSW feedstock processed the pyrolysis technology transforms hazardous materials into a number of main products such as activated carbon, Pyrolysis Oil Diesel and syn-gas, which can be reformed into Green Hydrogen or used for electricity production.
