Title: Novel sorbents for high temperature regenerative H/sub 2/S removal. Quarterly report No. 4, November 1984-January 1985

Abstract

The overall objective of this program is to develop improved regenerable sorbents for the high-temperature desulfurization of coal-derived gas streams. The aim is to reduce the H/sub 2/S level, preferably in a single stage, from a few percent down to 1 ppM. The specific objectives of this project are to synthesize, characterize and test two classes of sorbents. One consists of eutectic mixtures of metal oxides (e.g., ZnO-V/sub 2/O/sub 5/, CuMoO/sub 4/-MoO/sub 3/) in the form of a melt coating the pore surface of a high surface area solid support. The second class of sorbents includes unsupported mixed oxides, in the form of solid solutions or solid compounds, e.g., Zn-Fe/sub x/-O/sub y/, Cu-Fe/sub x/-O/sub y/, prepared as highly dispersed microcrystalline solids. The principal characteristics of both classes of sorbents are rapid kinetics of absorption, high absorption capacity and good regenerability. During this reporting period, parametric studies of sulfidation/regeneration with the mixed oxide sorbents CFA (Cu-Fe-Al-O) and CM (Cu-Mo-Al-O) both prepared in porous, microcrystalline form were performed. These two types of sorbents were identified in our previous work as very efficient, high performance materials for single-stage H/sub 2/S removal at temperatures higher than 600/sup 0/C. Experimental procedures and results are discussed.more » 15 refs., 4 figs., 4 tabs.« less
