Preliminary Tests of Batch Type Fluidized Bed Reactor for Development of Continuously-Feeding Fluidized Bed Reactor - An Elevated Temperature and Gasification Processes

A laboratory-scale prototype windowed internally circulating fluidized-bed reactor made of quartz sand and coal coke particles was investigated for steam gasification using concentrated Xe-light radiation as the energy source. The quartz sand was used as a chemically inert bed material for the fluidized bed, while the coal coke particles functioned as the reacting particles for the endothermic gasification reaction. The purpose of this study is a preliminary tests of batch type fluidized bed reactor that assuming a continuous feeding process of carbonous materials (cokes, coal, and biomass et al.) into the fluidized bed reactor with a thermal transfer/storage medium (quartz sand). The gasification performances such as the production rates of CO, H-2, and CO2 were evaluated for the fluidized bed reactor.
