Abstract
A mathematical model of a fluidized bed reactor for CO 2 separation from a synthesis gas is described. The proposed model specifies the operating process conditions required for production of hydrogen from coal hydro-gasification. The reactor behavior on the conversion of methane to hydrogen was dependent on the diffusion of CO 2 through the solid sorbent particle and the resistance of chemical reaction. Hydrogen and CO content of the synthesis gas leaving carbonator increased as the reactor temperature increased while methane content decreased simultaneously. The results can be regarded as a useful tool in a preliminary design of a carbonator. This is an abstract of a paper presented at the 18th International Congress of Chemical and Process Engineering (Prague, Czech Republic 8/24-28/2008).Pubblicazioni consigliate
