They use a thermal-catalytic pyrolysis technology. Nintech claims that the catalytic pyrolysis process produces a high quality of carbon black and the operation of the production line is steady.Difference Between Pyrolysis and Gasification | Compare,,29-08-2019· The key difference between pyrolysis and gasification is that pyrolysis is done in the absence of air while gasification is done in the presence of air.. Pyrolysis and gasification are two important processes that are used to decompose materials. Both these processes are different from combustion because the combustion is carried out in the presence of an excessive amount of oxygen.Waste Plastic Pyrolysis Process,Plastic Pyrolysis Process. The following is the simplified description of plastic pyrolysis process: 1. Put the plastics into the reactor. 2. Heat the reactor by using fuel materials, such as coal, charcoal, fuel gas, wood etc. The reactor will be slowly heated, when the temperature reaches around 250 degrees, the oil gas will be produced. 3.
