Primary Tar Reduction by Fe-Olivine as Catalytically Active Bed Material in a Dual Fluidised Bed System for Steam Gasification of Biomass

S. Koppatz, C. Pfeifer & H. Hofbauer
Tars and lower hydrocarbons are undesired products of every gasification process, since the condensation of these impurities causes clogging or blockage in downstream process units. Therefore these gaseous impurities are a central item in the development of biomass gasification. The present work focuses on primary tar reduction in a dual fluidised bed system for biomass steam gasification, since primary measures are a promising option for improvement of the overall gasification technology. Within the work a...
