A transient analysis of a fluid‐solid pyrolysis system in which a solid is pytolyzed to form a fluid product and a solid product is presented. The analysis, based on utilization of the so‐called volume reaction model, takes into account the simultaneous heat and mass transfer phenomena in the particle being pyrolyzed. Variations of physical parameters with respect to temperature and/or solid concentration are not neglected. Effects of the Lewis number on the solid conversion, the fluid and solid concentration distributions, and the temperature profile in the particle are examined. The results are graphically presented and interpreted.
