Abstract
The present invention relates to a regenerable hydrogen sulfide adsorbent and a preparation method thereof. The preparation method specifically includes: 1) combining meta-aluminate as an active component with activated alumina as a carrier in a manner of impregnation, spray coating or solid phase mixing to obtain a precursor; 2) aging and drying the precursor, and finally performing roasting to obtain the adsorbent; and 3) processing the adsorbent to present a specific size and shape through shaping measures to meet industrial application requirements. Compared with the prior art, the adsorbent obtained according to the present invention can achieve an efficient removal effect on hydrogen sulfide gas at a material inlet, with a concentration adaption range of 0 to 1000 ppm and an effective removal precision of 0.1 ppm or below.
