OSTI ID:10109431
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{degree}C (1022-1472{degree}F). The specific objectives of the project are to: (i) develop combined sorbent-catalyst materials capable of removing hydrogen sulfide to less than 20 ppmv and ammonia by at least 90 percent. (ii) Carry out comparative fixed-bed studies of absorption and regeneration with various formulations of sorbent-catalyst systems and select most promising sorbent-catalyst type. (iii) Conduct long-term (at least 30 cycles) durability and chemical reactivity in the fixed-bed with the superior sorbent-catalyst.
