Journal ArticleDOI
Reaction mechanisms and multi-scale modelling of lignocellulosic biomass pyrolysis
TL;DR: In this article, the authors describe pyrolysis of lignocellulosic biomass, and the individual reaction mechanisms of cellulose, hemicellulose and lignin are initially described.
Journal ArticleDOI
A Generalized Biomass Pyrolysis Model Based on Superimposed Cellulose, Hemicelluloseand Liqnin Kinetics
Richard S. Miller,Josette Bellan +1 more
TL;DR: In this paper, the pyrolysis of general biomass materials is modeled via a superposition of cellulose, hemi-cellulose and lignin kinetics.
Journal ArticleDOI
Pyrolysis, a promising route for biomass utilization
TL;DR: In this paper, the influence of the main process parameters on the yields and characteristics of the products has been investigated and the differences between convertional and fast pyrolysis can be discussed.
Journal ArticleDOI
Kinetic and Heat Transfer Control in the Slow and Flash Pyrolysis of Solids
TL;DR: In this article, the coupled effects of particle size and external heating conditions (reactor heating rate and final temperature) on cellulose pyrolysis were investigated by means of a computer model accounting for all main transport phenomena, variable thermophysical properties and primary, and secondary reaction processes.
Journal ArticleDOI
Biomass Pyrolysis in a Fluidized Bed Reactor. Part 1: Literature Review and Model Simulations
TL;DR: The literature on biomass pyrolysis regarding kinetics, models (single particle and reactor), and experimental results is reviewed from an engineering point of view in this article, where the main conclusions from the literature and modeling studies can be summarized as follows: (1) the available knowledge on kinetics and transport phenomena has not been integrated properly for reactor design, (2) complex two-dimensional single particle models do not provide more accurate, or otherwise better, information for engineering calculations than do the simple one-dimensional models, and (3) single-particle models predict (

Journal ArticleDOI
A kinetic model for pyrolysis of cellulose.
TL;DR: In this article, it was shown that the pyrolysis of cellulose at low pressure (1.5 Torr) can be described by a three reaction model, where an initialization reaction leads to formation of an active cellulose which subsequently decomposes by two competitive first-order reactions, one yielding volatiles and the other char and a gaseous fraction.
Journal ArticleDOI
Production of levoglucosan and glucose from pyrolysis of cellulosic materials
TL;DR: In this paper, it was found that pyrolysis proceeds at a much faster rate at the higher temperatures without detrimental effect on the yields, yielding a tar that contained 39% levoglucosan and, upon mild acid hydrolysis, gave 49% Dglucose.

The flash pyrolysis of aspen-poplar wood
Donald S. Scott,Jan Piskorz +1 more
TL;DR: In this article, a continuous fluidized bed bench scale flash pyrolysis unit operating at atmospheric pressure and feed rates of about 15 g/h has been successfully designed and operated.

Software for Nonlinear Partial Differential Equations
TL;DR: The software interface provides centered differencing in the spatial variable for time-dependent nonlinear PDEs, giving a semidiscrete system of nonlinear ordinary differential equations (ODEs), which are then solved using one of the recently developed robust ODE integrators.
