VALIDATION OF A KINETIC MODEL FOR THE CATALYZED WATER GAS SHIFT REACTION APPLYING A FE/CR CATALYST PROCESSING PRODUCT GAS FROM BIOMASS STEAM GASIFICATION

摘要

In this work, a kinetic model of the catalyzed water gas shift reaction applying a Fe/Cr based catalystrnfound from investigations in a micro reactor test rig is validated with experimental data from a pilot plant water gasrnshift reactor. The reactor was fed with product gas from an industrial biomass dual fluidized bed steam gasificationrnplant. The validation was done with product gas upstream a rapeseed methyl ester gas scrubber and product gasrndownstream a rapeseed methyl ester gas scrubber of the biomass gasification plant. In both cases, the calculated andrnmeasured values of the concentrations at the outlet of the reactor showed good agreement. However, the model showsrninaccuracy regarding the temperature profile at the entrance of the reactor. If the kinetic model can be improved andrnadapted, it could be useful for basic design and engineering of an industrial scale water gas shift reactor applying arnFe/Cr based catalyst and processing product gas from biomass steam gasification.
