A method for removal of hydrogen sulfide and mercury from a gaseous stream containing hydrogen sulfide and mercury in which a hydrogen sulfide conversion catalyst is contacted with the gaseous stream at a temperature less than or equal to the dewpoint of elemental sulfur, and the hydrogen sulfide is oxidized, forming elemental sulfur.

Method for direct oxidation of hydrogen sulfide to elemental sulfur at low temperatures

Disclosed is a multiple stage process wherein a hydrocarbon feedstock is hydrotreated in a hydrotreating stage. After removal of ammonia and hydrogen sulfide from the hydrotreated feedstock, the hydrotreated feedstock is hydrocracked in a three zone hydrocracking stage.

Two stage hydrocarbon conversion process

A two-stage hydrocarbon process is disclosed wherein a hydrocarbon feedstock is first hydrotreated followed by a hydrocracking step wherein a portion of the hydrotreated feedstock is hydrocracked in the presence of a catalyst having a nickel component, a tungsten component, and a support component containing a crystalline molecular sieve material present in an amount ranging from 25 to 60 wt. % based on the weight of the support component with the balance being alumina.
