The effect of process conditions on coal pyrolysis and char reactivity
The effect of process conditions on coal pyrolysis and char reactivity is systematically studied using the thermogravimetric reactor equipped with in-situ video microscopy imaging (TGA/VMI). This system provides a complete ...
Influence of pyrolysis conditions on macropore structure of char particles
A systematic analysis of the structure of char particles produced from an Illinois #6 coal was carried out. Coal particles were pyrolyzed in a hot-stage reactor under inert (N$\sb2$) and reactive (5% O$\sb2$ / 95% N$\sb2$) ...
Ignition of coal and char particles: Effects of pore structure and process conditions
This study reports the results from experimental and theoretical studies aimed at elucidating the effects of particle pore structure and process conditions on the ignition of coal and char particles. A novel reactor combining ...
Fundamental mechanisms of coal pyrolysis and char combustion
Coal pyrolysis and combustion have been systematically investigated at high temperatures where external and intraparticle transfer limitations become important. A thermogravimetric reactor equipped with in-situ video imaging ...
Transient heat and mass transfer in two monolith reactor passage geometries
Transient two dimensional mass and energy balance models of a monolith reactor are formulated and solved using a combination of analytical and numerical algorithms. The reactor passage has three distinct phases: the void ...
