Hot low Btu producer gas desulfurization in fixed bed of iron oxide-fly ash. Monthly report No. 9, 1 March--31 March 1976. Quarterly report No. 3, 1 January--31 March 1976
Major emphasis in this period has been in the preparation, and dynamic absorption testing of experimental sorbents. The studies of physical properties and chemical analyses of the prepared sorbents, a method for analyzing dynamic test data is explained and the effects of the following variables on sorption dynamics are presented: Sorbent iron oxide content, GHSV at constant linear velocity (GHSV = bed gas hourly space rates (SCFH/ft/sup 3/ bed), linear velocity at constant GHSV, temperature, pressure, sorbent particle size, and producer gas H/sub 2/S content. The dynamic test data indicate that optimum sorbent performance is obtained at 42 percent by weight iron oxide. The effect of GHSV at constant velocity provides a basis for an empirical sorption dynamics model. A significant effect of bed geometry on sorbent performance was discovered. Test results indicate the sorbent will totally disintegrate when exposed to sulfur-free producer gas at 900/sup 0/F. At a given GHSV, the best sorbent performance is observed at high pressure, high linear velocity, and small sorbent particle size. Two isothermal sorption models derived from fundamental principles and the empirical model are compared with dynamic test results. The empirical model was superior.
