Studies Involving High Temperature Desulfurization/Regeneration Reactions of Metal Oxides for Fuel Cell Developments. Project Status Report, December 1982

摘要

The test evaluation of supported system CuO/Zeolite was carried out in the fluidized bed reactor with 450 mean average particle diameter. In all the tests, the sulfur capacity was observed below 1 mole % conversion for 10 ppM H sub 2 S concentration in the effluent gas. There was an improvement in sulfur capacity of air-steam regenerated batches (Run 171 and 172) compressed to air regenerated batches (Run 169 and 170). We believe CuO-ZnO system has greater potentials than supported CuO only. We plan to carry out a desulfurization test of mixed oxide CuO/ZnO sorbent with ZrO sub 2 as diluent. (ERA citation 10:019687)
