Abstract
After a decade of extensive research, a number of solid sorbents have been identified as being suitable for the high-temperature removal of H2S from coal gas. Current activities are aimed at the development of a continuous desulfurization process through reactor studies and pilot-plant testing. In this paper, the influence of various parameters related to the type of sorbent, the type of reactor, and the required process conditions, are discussed, and elucidated for the promising iron-oxide based sorbents as a typical example.
