Processes for Removing Polysulfanes and Elemental Sulfur from Hydrogen Sulfide

摘要

Disclosed are processes for purifying feed streams containing hydrogen sulfide and sulfur-containing impurities by removing sulfur-containing impurities, such as elemental sulfur and polysulfanes, using solid catalytic sorbents. Also disclosed are processes for producing hydrogen sulfide.

主权项

1. A process to purify a feed stream comprising hydrogen sulfide and sulfur-containing impurities, the process comprising:
contacting the feed stream with a solid catalytic sorbent to remove at least a portion of the sulfur-containing impurities from the feed stream to form a purified H2S stream; wherein the solid catalytic sorbent comprises a clay; an alkali metal hydroxide or alkaline earth metal hydroxide impregnated activated carbon; an alkali metal hydroxide or alkaline earth metal hydroxide impregnated alumina; an alkali metal hydroxide or alkaline earth metal hydroxide impregnated alumina combined with a clay; an alkali metal hydroxide or alkaline earth metal hydroxide impregnated alumina combined with an activated carbon;or any combination thereof.
