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 کاملBiofuel Production and Kinetics Study of Catalytic Microwave Pyrolysis of Douglas Fir Pellet over Activated Carbon Supported Metal Catalyst
The presented study aims to improve the quality of bio-oils by catalytic upgrading of pyrolysis bio-oil from microwave pyrolysis of biomass using transition metal modified activated carbon (AC) catalyst. A central composite experimental design (CCD) was used to optimize the reaction conditions for high quality bio-oil production. The effects of reaction temperature and reaction time on product ...
متن کاملRenewable phenols production by catalytic microwave pyrolysis of Douglas fir sawdust pellets with activated carbon catalysts.
The effects of different activated carbon (AC) catalysts based on various carbon sources on products yield and chemical compositions of upgraded pyrolysis oils were investigated using microwave pyrolysis of Douglas fir sawdust pellets. Results showed that high amounts of phenols were obtained (74.61% and 74.77% in the upgraded bio-oils by DARCO MRX (wood based) and DARCO 830 (lignite coal based...
متن کاملCatalytic Microwave Pyrolysis of Douglas Fir Pellets with Carbon Catalysts Derived from Corn Stover
This study investigated catalytic microwave pyrolysis of Douglas fir sawdust pellets using carbon catalysts produced from corn stover. The effects of catalyst to biomass ratio on the bio-oil, syngas, and biochar yields were determined. Functional groups (carbonyls, phenolics, lactones, carboxyls) of carbon catalysts and GC/MS analysis were used to study the catalytic pyrolysis of Douglas fir sa...
متن کاملPyrolysis and catalytic pyrolysis of protein- and lipid-rich feedstock
In this study, pyrolysis of microalgal remnants was investigated for recovery of energy and nutrients. Chlorella vulgaris (C.vulgaris) biomass was first solvent-extracted for lipid recovery then the remnants were used as the feedstock for fast pyrolysis experiments using a fluidized bed reactor at 500 o C. Yields of bio-oil, biochar and gas were 53, 31, and 10wt.%, respectively. Bio-oil from C....
