APPLICATION TITANIA-BASED COMPOSITION AS CATALYST FOR COS AND/OR HCN HYDLOLYSIS IN GASEOUS MIXTURE Russian patent published in 2007 - IPC B01J27/53 B01D53/86 C01B17/50 B01D53/48 B01D53/60

Abstract RU 2297878 C2

FIELD: catalyst for improved hydrolysis of carbon oxysulfide (COS) and hydrocyanic acid (HCN) in gaseous mixtures.

SUBSTANCE: invention relates to application of TiO₂-based composition as catalyst for COS and/or HCN in gaseous mixture releasing from apparatus for joint energy production, wherein said composition contains H₂, CO, H₂S and H₂O in amounts of 10-40 %; 15-70 %; 200 ppm-3 % and 0.5-25 %, respectively. Moreover abovementioned composition contains at leas 1 mass.%, preferably at least 5 % at least one alkali-earth metal sulfate selected form calcium, barium. Strontium, and magnesium.

EFFECT: high conversion ratio of COS and HCN, irresponsiveness to presence of NH₃, decreased production of CO₂ and CH₄.
