“…In 2011 Brown et al (2011) presented modelling and analysis for estimating profitability of two biochar production scenarios: slow pyrolysis vs fast pyrolysis [219]. Although, a large number of other studies have been carried out to simulate pyrolysis process using CFD, however most of them conducted analysis on fluidized bed reactors [216,[220][221][222]. Those studies illustrated that; CFD models could be advantageous in the virtual design of fast pyrolysis reactors and optimising the design of reactor.…”

There has been an enormous amount of research in recent years in the area of thermo-chemical conversion of biomass into bio-fuels (bio-oil, bio-char and bio-gas) through pyrolysis technology due to its several socio-economic advantages as well as the fact it is an efficient conversion method compared to other thermo-chemical conversion technologies. However, this technology is not yet fully developed with respect to its commercial applications. In this study, more than two hundred publications are reviewed, discussed and summarized, with the emphasis being placed on the current status of pyrolysis technology and its potential for commercial applications for bio-fuel production. Aspects of pyrolysis technology such as pyrolysis principles, biomass sources and characteristics, types of pyrolysis, pyrolysis reactor design, pyrolysis products and their characteristics and economics of bio-fuel production are presented. It is found from this study that conversion of biomass to bio-fuel has to overcome challenges such as understanding the trade-off between the size of the pyrolysis plant and feedstock, improvement of the reliability of pyrolysis reactors and processes to become viable for commercial applications. Further study is required to achieve a better understanding of the economics of biomass pyrolysis for bio-fuel production, as well as resolving issues related to the capabilities of this technology in practical application.

“…[118]. Yuen et al [123] developed a three dimensional mathematical model for pyrolysis of a beech wood cube considering moisture evaporation, anisotropic properties and its effect on heat and mass transfer by using a multiple competing reaction model. Results showed a significantly faster moisture evaporation rate in the direction along the particle (cube) due to the higher permeability along the cube.…”

“…In a recent investigation, Zhang et al [123] proposed a reaction rate of volatiles that is only controlled by mixing the process. Detailed CFD simulation of fixed-beds showed a decreasing mixing rate of volatile gases above the bed with increasing distance from the bed top surface [131].…”

“…A recently published work of Yuen et al [2] reports a 3D model of 5 mm wooden cubes undergoing pyrolysis in a convective environment. This model considers most of the processes but neglects shrinkage during A two-dimensional (2D) mathematical model in cylindrical coordinates has been formulated and used to predict the progress of conversion in a cylindrical wood particle undergoing pyrolysis in a fluidized bed.…”

“…But most of them are in 1D and most of the available 2D models are formulated for cuboid shaped wood. The only 3D model [2] is also formulated for cuboids. The only 2D model in cylindrical coordinates incorporating shrinkage is that of Bellais et al [12], but the model is meant for a single particle reactor with lowheating rate and drying has been neglected.…”
