The objective of the option 3 program within this contract is to develop chemically reactive and mechanically durable mixed-metal oxide sorbent formulations that are suitable for moving-bed, high-temperature, desulfurization of coal gas. One optimum formulation will be evaluated in a pressurized 50-cycle bench-scale test. Work on zinc titanate formulations was initiated under the option 2 program and is continued under the present option 3 program along with testing of other mixed-metal oxides. One of the major limitations for large-scale use of mixed-metal oxides is the observed weakening and physical deterioration of the pellet and spalling during repetitive use in cycles of absorption and regeneration. A need exists to determine best operating conditions that minimize sulfate formation and prevent mechanical degradation. Results from materials tests on 5 zinc-based sorbents are given.
