Catalytic Pyrolysis of Biomass with Fe/La/SBA-15 Catalyst using TGA–FTIR Analysis

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...

Effect of Catalytic Pyrolysis Conditions Using Pulse Current Heating Method on Pyrolysis Products of Wood Biomass

The influence of catalysts on the compositions of char and pyrolysis oil obtained by pyrolysis of wood biomass with pulse current heating was studied. The effects of catalysts on product compositions were analyzed using GC-MS and TEM. The compositions of some aromatic compounds changed noticeably when using a metal oxide species as the catalyst. The coexistence or dissolution of amorphous carbo...

Catalytic Fast Pyrolysis of Biomass in a Bubbling Fluidized Bed Reactor with Gallium Promoted Zsm-5 Catalyst

Catalytic Pyrolysis of General Purpose PolyStyrene Using Red Mud as a Catalyst

Phenol and phenolics from lignocellulosic biomass by catalytic microwave pyrolysis.

Catalytic microwave pyrolysis of biomass using activated carbon was investigated to determine the effects of pyrolytic conditions on the yields of phenol and phenolics. The high concentrations of phenol (38.9%) and phenolics (66.9%) were obtained at the temperature of 589 K, catalyst-to-biomass ratio of 3:1 and retention time of 8 min. The increase of phenol and its derivatives compared to pyro...
