Bench-scale demonstration of hot-gas desulfurization technology. Quarterly report, July 1 - September 30, 1995

The goal of this project is to continue further development of the zinc titanate desulfurization and Direct Sulfur Recovery (DSRP) technologies by: scaling up the zinc titanate reactor system; developing an integrated skid-mounted zinc titanate desulfurization-DSRP reactor system; testing the integrated system over an extended period with real coal-gas from an operating gasifier to quantify the degradative effect, if any, of the trace contaminants present in coal gas; developing an engineering database suitable for system scaleup; and designing, fabricating and commissioning a larger DSRP reactor system capable of operating on a six-fold greater volume of gas than the DSRP reactor used in the bench-scale field test. This report discusses the field testing of the Zinc Titanate Fluid Bed Desulfurization/DSRP at the Morgantown Energy Technology Center
