Description

Work has continued on application of this technology to polishing H{sub 2}S from simulated coal gasification process streams. Both stainless steel and MACOR housings were successfully used, with 98% (100 ppmv H{sub 2}S to 2 ppmv H{sub 2}S) removal observed at a flow rate of 230 cc/min and a process temperature of 700{degrees}C with stainless steel housings (Run 57) and greater than 80% (11 ppmv H{sub 2}S to less than 2 ppmv H{sub 2}S) at a flow rate of 100 cc/min and a temperature of 650{degrees}C with MACOR housings (Run 65). Work has continued with attempts to increase removal efficiency … continued below

Work has continued with attempts to increase removal efficiency by increasing the density of the membrane and slowing down H{sub 2} diffusion from the cathode side to the anode side of the cell.
