Catalytic Pyrolysis of Vacuum Gas Oil

Chemistry and Technology of Fuels and Oils, 2021
Studies of thermal and catalytic pyrolysis of vacuum gas oil in a flow-type reactor have been carried out. The main regularities in the yield of the target products of the process – ethylene, propylene and butylenes – are revealed. The influence of the catalyst on the change in the conditions of catalytic pyrolysis in comparison with thermal pyrolysis ...

Kinetics of biomass catalytic pyrolysis

Biotechnology Advances, 2009
The Coats-Redfern method was used to analyze the kinetic characteristics of biomass catalytic pyrolysis, indicating that it can be described by multi-step reactions, rather than as a simple first-order reaction. Friedman model-free calculations were used to describe the starting reaction types and the corresponding initial kinetic parameters.
