Abstract:

In the production of syngas from biomass gasification the resulting raw gas needs to be low in both tar and particulates but also optimized in its composition. Different bed materials have been studied in the purpose of catalytically reducing tars. The set-up has been in lab-scale and naphtalene has been used as a model substance. One problem that can occur when using porous and active bed materials is abrasion of the solids which causes formation of fine particles that can not be recirculated in the process cyclone. Other limiting factors are poor catalytic effectiveness and high costs for the new materials. The objective of this study is to investigate potentially cost­efficient, mechanically stable and catalytically active bed-materials.
