Integrated catalytic adsorption steam gasification in a bubbling fluidized bed for enhanced H2 production: Perspective of design and pilot plant experiences

It is important to build knowledge about the design of an integrated catalytic adsorption (ICA) steam gasification process in a bubbling fluidized bed, which can reduce CO2 content with enhanced hydrogen production. The value of this study is its presentation of detailed design considerations for th...
