Investigation on durability and reactivity of promising metal oxide sorbents during sulifidation and regeneration: Technical progress report for July 1--September 30, 1996

PDF Version Also Available for Download.

Description

The main objectives of this research project during this quarter are to formulate metal oxide sorbents using various ingredients as well as formulation conditions, and test reactivity of formulated metal oxide sorbents with hydrogen sulfide for 120 seconds at 550{degrees}C, and develop a formula of a sorbent suitable for the removal of hydrogen sulfide from hot coal gases. Metal oxide sorbents were formulated with zinc oxide as an active sorbent ingredient, and titanium oxide as a supporting metal oxide. Various additives such as Al, Ce, Zr, Cu, Co, Ni, Mn, Cr and Ca were utilized to enhance sulfur-removal capacity of ... continued below

Metal oxide sorbents were formulated with zinc oxide as an active sorbent ingredient, and titanium oxide as a supporting metal oxide. Various additives such as Al, Ce, Zr, Cu, Co, Ni, Mn, Cr and Ca were utilized to enhance sulfur-removal capacity of formulated metal oxide sorbents. The additives Cu and Co appear to enhance reactivity of sorbents in the reaction with wet hot hydrogen sulfide at 550{degrees}C. Durability of formulated sorbents appears to improve with kaolin binder in comparison with bentonite binder. Durability of formulated sorbents appears to improve with increased calcination durations. Reactivity of sorbents formulated with Co additive appears to decrease with increased calcination durations at the calcination temperature of 860{degrees}C. Reactivity of sorbents formulated with Cu additive appears to increase with calcination durations. Reactivity of sorbents formulated without additive appears to be independent of calcination durations.
