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 کاملUpgrading of Pyrolysis Bio-oil: A Review
The increase in the population of the planet and the rapid economic growth and, consequently, the high consumption of energy has created many environmental problems in the globe. Due to these reasons and the lack of renewability of these fossil fuels, there has been a steep trend towards the production of renewable fuels from natural sources, one of which is the production of energy from biomas...
متن کاملNonlinear Analysis of Integrated Kinetics and Heat Transfer Models of Slow Pyrolysis of Biomass Particles using Differential Transformation Method
The inherent nonlinearities in the kinetics and heat transfer models of biomass pyrolysis have led to the applications of various numerical methods in solving the nonlinear problems. However, in order to have physical insights into the phenomena and to show the direct relationships between the parameters of the models, analytical solutions are required. In this work, approximate analytical solu...
