A drying model for thermally large biomass particle pyrolysis

Kinetic 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),...

Biomass Pyrolysis for Hybrid Biorefineries

A Gcncralizxd Biomass Pyrolysis Model Based on Superimposed Cellulose , IIemi -

AIEWRACT-The pyrolysis of general biomass materials is modeled via a superposition of cellulose, hcmiccllulosc and lignin kinetics. All three of the primary biomass components arc modeled with multi-slcp kinetics involving both compcte-tivc primary pyrolysis and secondary tar decomposition reactions. Only " typical " (untreated) fccdstocks arc considered at at mosphcric pyrolysis pressures. The...

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...
