While the process of circulating fluidized bed can overcome this defect and the catalyst can maintain good catalytic activity in the whole process. Cs (8%) P (5%) K (2%)/-Al 2 O 3 / catalyst showed better performance due to its high surface area and more weak basicity and acidity. In addition theoretical calculations and cold model experiments were also conducted in this work to determine the catalyst

The production of a hydrogenrich gas from biomass can be established by the AER (absorption enhanced reforming) process. Based on the dual fluidized bed steam gasification process it uses a bed material which apart from its function as heat carrier acts as a CO 2 transporting agent and selectively transfers CO 2 from the gasification reactor to the combustion reactor.
