In this study, a theoretical model of biomass char gasification reactivity was developed, focusing on the catalytic effect of inorganic elements on the char gasification process. A comparison with previous research results shows that the catalytic ability of K in a fixed bed reactor is stronger than that of Ca, while the catalytic ability of Ca in ...

Understanding apparent kinetics of single large fuel particle combustion is of significance to the design and optimization of grate-firing and circulating fluidized bed boilers. Based on the concept of finite reaction zone approximation, a simple heterogeneous single particle model was formulated to consider the effects of external gas film, ash la...

Granular bed filtration is considered one of the most promising engineering solutions to the dust removal from high temperature coal pyrolytic vapors. Expanded perlite as filtration media was studied in a lab-scale fixed bed reactor to understand its effect on pyrolysis products. Factors including filtration temperature, filtration time, dust accum...

In this work, the structural function of char gasification is modelled theoretically. Considering that different components will have different pore characteristics after pyrolysis, char is divided into different micro-structures according to its corresponding components, and then a structural equation is constructed to realize the theoretical calc...

A model was established to describe the effects of inorganic matter on the char-CO2 gasification reactivity. The effects of seven inorganic elements on the char-CO2 reactivity were considered: K, Na, Ca, Mg and Fe, which play a catalytic role, and Si and Al, which play an inhibitory role. A catalytic/inhibitory index factor model and a saturated ca...
