Utilization of Fireclay for Preventing Fluidized-Bed Agglomeration during Biomass Thermochemical Processing

This article reports a research aimed at investigating agglomeration phenomena during fluidized-bed thermochemical processing of olive husk biomass and their mitigation, taking into account both combustion and gasification conditions. Agglomeration is due to the presence of alkalis in fuel ash producing low-melting compounds in combination with SiO2 present in common bed materials (e.g., silica sand). The use of kaolin and fireclay as additives...
