Abstract:
In this present paper, the performance of a commercial Fe/Cr based catalyst for the water gas shift reaction was investigated. The catalyst was applied in a water gas shift pilot plant which processed product gas from a commercial biomass steam gasification plant for combined heat and power. The water gas shift pilot plant successively processed product gas upstream and downstream a rapeseed methyl ester gas scrubber. During the investigations, extensive chemical analyses were carried out. The main components (CO, CO2, CH4, N2, O2, C2H6, C2H4, and C2H2) and sulfur components (H2S, COS, and C4H4S) were measured. In addition, tar and NH3 analyses were performed. Furthermore, the catalyst’s activity was observed by measuring the temperature profiles along the reactors of the water gas shift pilot plant. During the operation, no catalyst deactivation could be observed. A CO conversion up to 94 % was reached. The results showed that the application of a Fe/Cr based catalyst in a water gas shift unit seems to be a suitable way for increasing the hydrogen content in the product gas which was generated by biomass steam gasification. Furthermore, with such a technique it is possible to adjust the required CO/H2 ratio for several syntheses reactions (e.g. methanation, Fischer Tropsch) in an optimal way.
