Kinetics of biomass catalytic pyrolysis.
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. Finally, nonlinear regression of biomass catalytic p...
متن کاملDehydration and Dehydrogenation Kinetics of OH Groups in Biomass Pyrolysis
Experiments in pulse-injected flow reactors show that gas-phase pyrolysis of alcohols makes a transition from dehydrogenation dominance for mono-alcohols to dehydration and fragmentation for tested diols and a triol. These dehydration and dehydrogenation reactions are proposed to occur by unimolecular and bimolecular pericyclic reactions, as has been used to explain glucose and cellulose pyroly...
متن کاملKinetic models for biomass pyrolysis
Biomass is a versatile material. It can be directly combusted to produce heat; however, by first subjecting it to a thermal or biological degradation, it can also be converted to products with a higher heating value or to materials with properties superior to those of the raw material [1]. When heated in the absence of oxygen, biomass decomposes into a range of products; including char (solid),...
