OBJECTIVES The objective of this study is to develop advanced high-temperature coal gas desulfurization mixed-metal oxide sorbents with stable ammonia decomposition materials at 550-800°C (1022-1472°F). The specific objectives of the project are to: l . Develop a combined sorbent-catalyst materials shall be capable of removing hydrogen sulfide to less than 20 ppmv and ammonia by at least 90 percent. , Carry out comparative fixed-bed studies of absorption and regeneration with various
more » ... s of sorbent-catalyst systems and select most promising sorbent-catalyst type.
