Sorbent for removing hydrogen sulfide from hot gas and the process for its preparation

摘要

the invention discloses sorbent for removal of hydrogen sulfide from the hot gas, which contains a mixture of oxides: zinc oxide in a quantity of from 8% to 30 mole%, titanium dioxide in quantities of from 25% to 50 mole%, iron oxide in quantities of from 15 to 50 mole%, cobalt oxide in a quantity of from 0.1 to 4 mole% lu b a nickel oxide in quantities of from 0.1 to 4%.to 30 mass% silicon dioxide advantageously forming structure type spinelu and 50 mass% binders. the invention concerns also the sorbent for removal of hydrogen sulfide from receiving the hot gas.the way is that the suspension of titanium dioxide in solution of zinc, nickel and cobalt or iron salt is added ammonia solution, and the separated sludge is filtered out and dried at room temperature, is in 600 - 900u00b0c, after which is chopped and added binders, subsequently, forming, drying in 110u00b0c then swelters in 900u00b0c.
