Syngas production using straw pellet gasification in fluidized bed allothermal reactor under different temperature conditions

Straw is one of the most available agriculture waste materials to be utilized as resource. Straw gasification for syngas production is one of the alternatives for resource recovery. Nevertheless, straw gasification might be problematic due to high alkali content, which may cause fouling of the gasifier reactor. In the present study, straw was gasified at different temperatures; in particular 750 degrees C, 800 degrees C, 850 degrees C, 900 degrees C, and 950 degrees C furnace temperature, was evaluated and then compared with wood feedstock using allothermal gasifier. The tested temperatures are not the limiting factor for the wood gasification using olivine (Mg2+,Fe2+)(2)SiO4 bed material and catalysis. Relatively, lower temperature is appropriate for straw gasification where agglomeration with bed material was observed at a higher temperature.
