Claims
- 1. A process for removing hydrogen sulfide from a hydrogen sulfide contaminated light hydrocarbon gas stream wherein said light hydrocarbon gas comprises a compound selected from the group consisting of methane, ethane, and natural gas, said process comprises the step of contacting said hydrogen sulfide contaminated light hydrocarbon gas stream at a temperature in the range of from about 150.degree. C. to about 600.degree. C. with a sorbent composition comprising a co-gelled mixture comprising hydrated zinc oxide and hydrated silica, having been prepared by mixing said hydrated zinc oxide and said hydrated silica followed by adding to the thus formed mixture a suitable base, to thereby remove hydrogen sulfide from said hydrogen sulfide contaminated light hydrocarbon gas stream.
- 2. A process as recited in claim 1 wherein the hydrated silica is present in said co-gelled mixture ranging upwardly to about 60 parts by weight per 100 parts by weight of the total combined weight of said co-gelled mixture.
- 3. A process as recited in claim 2 wherein said co-gelled mixture is calcined.
- 4. A process as recited in claim 1 wherein said hydrated zinc oxide is contained in the form of an acidified slurry of zinc oxide and said hydrated silica is contained in the form of an acidified solution of sodium silicate.
- 5. A method of improving a process for removing hydrogen sulfide from a hydrogen sulfide contaminated light hydrocarbon gas stream wherein said light hydrocarbon gas comprises a compound selected from a group consisting of methane, ethane, and natural gas, said sorbent composition is prepared by the steps comprising:
- mixing an acidified slurry of zinc oxide with an acidified solution of sodium silicate;
- adding a base to the thus formed mixture suitable for causing the formation of a co-gelled mixture comprising zinc oxide and silica;
- calcining said co-gelled mixture; and
- contacting said hydrogen sulfide contaminated light hydrocarbon gas stream with said co-gelled mixture at a temperature in the range of from about 150.degree. C. to about 600.degree. C. to thereby remove hydrogen sulfide from said hydrogen sulfide contaminated light hydrocarbon gas stream.
