TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred System: The hydrolysis catalyst is provided in a first zone and the sorbent material is provided in a second zone in communication with the first zone. The first zone is a fixed bed comprising the hydrolysis catalyst, and the second zone is a fixed bed comprising the sorbent material. The at least one vessel has an inlet unit providing communication between a hydrocarbon stream source. The first zone of the at least one vessel is located vertically above the second zone.Preferred Components: The hydrolysis catalyst comprises alumina and the sorbent material comprises zinc oxide. The first sulfur compound is selected from carbonyl sulfide and/or carbon disulfide.Preferred Process: Step (A) is carried out at 300-450degreesC and pressure of 100-5000 kPa. The hydrocarbon-containing stream is contacted with the hydrolysis catalyst in a first zone of the first vessel and the hydrocarbon-containing stream is contacted with the sorbent material in a second zone of the first vessel at the same above temperature and pressure conditions. The carbonyl sulfide is present in the hydrocarbon-containing stream at a concentration of 5-1000 vppm and water is present in the hydrocarbon-containing stream at molar ratio of water to carbonyl sulfide of 1:1-100:1. The first stream having a reduced content of the first sulfur compound with a carbonyl sulfide content of less than 1 vppm. The first stream having a reduced content of the first sulfur compound is directed to a second vessel and contacted at 300-450degreesC and a pressure of 100-5000 kPa, with the catalyst to produce a second stream comprising the second sulfur compound and directing the second stream comprising the second sulfur compound to the sorbent material to produce a second stream having a reduced content of the first sulfur compound. EXAMPLE - Hydrocarbon-containing stream was contacted with DD-431 (RTM; an activated alumina) (17.5 ml) and then with ZN-0401 E3/16 (RTM; zinc oxide) (52.5 ml) in a single reaction vessel at 370degreesC and pressure of 100 kPa. The results of for conversion of N2 (vol.%)/CH2 (%)/COS (vppm)/COS (%) during 0.5; 1.5; 2.5 and 3 hours at space velocity of 6000/hour were found to be 3.24/96.83/0.12/99.9; 3.19/96.75/0.19/99.8; 3.12/96.57/0.11/99.9 and 3.06/96.68/0.13/99.9 respectively.
