Reactivity Effects of Inorganic Content in Biomass Gasification: A Review

This review article discusses the effects of inorganic content and mechanisms on raw biomass char during gasification. The impacts inherent inorganics externally added compounds are summarized based a literature search from most recent 40 years. TGA larger-scale studies involving K-, Ca-, Si-related critically reviewed with aim understanding reaction kinetics. Differences between pathways matter, subsequent reactivity gasification, discussed. present results illustrate complexity ash transformation phenomena, which have strong impact design gasifiers as well further operation process control. impregnation mixing catalytic into emphasized potential solution to avoid reactivity-related operational challenges steam CO2 clearly identifies gap in experimental knowledge at micro macro levels advanced modelling respect gasification reactivity.
