High temperature hydrogen sulfide removal
The objective is to develop and test a regenerable stannic oxide-based sorbent to remove H{sub 2}S from hot coal gases while producing sulfur as the only product. The detailed technical objectives in support of this are: (1) Develop mechanically strong and chemically inert support materials which will retain their properties through multiple absorption regeneration cycles. (2) Develop mathematical models to predict the performance of large-scale systems from benchscale results. (3) Test the durability of the best sorbent/support combinations. (4) Conduct a bench-scale proof of concept test with the best stannic-oxide sorbent. Several approaches are being used to develop long-life sorbents. The investigators have tested sorbents produced by agglomeration, pressing, and extrusion. To date over 50 formulations have been tested, with several showing promise. Table II presents the results on five of these formulations; all of these formulations had surface areas in excess of 2 m{sup 2}/gm. All of the formulations meet the goals for porosity, tin content, and surface area. The crush strength for a 1/8inches dia. by 1/8inches long sorbent is significantly affected by the method of preparing the sorbent.
