PROCESSES FOR THE REDUCTION IN THE QUANTITY OF SULFUR COMPOUNDS, HYDROGEN CYANIDE, FORMIC ACID AND FORMIC ACID DERIVATIVES IN SYNTHESIS GAS, FOR THE PREPARATION OF METHANOL, DIMETHYL ESTER AND / OR HYDROCARBONS IN GASES OR LIQUID FORM OF GASES OF SYNTHESIS , AND, FOR THE PRESENTATION OF LIQUID HYDROCARBONS FROM GASES OF SYNTHESIS

摘要

A process for a reduction in the amount of sulphur compounds, hydrogen cyanide, formic acid and formic acid derivatives in synthesis gas comprising these compounds, the process comprising contacting the synthesis gas with a sulphur absorbent comprising material and thereafter with a catalyst comprising one or more metals selected from the group consisting of silver, gold, copper, palladium, platinum and their mixtures and supported on a carrier comprising at least one of the oxides of scandium, yttrium, lanthanum, cerium, titanium, zirconium, aluminum, zinc, chromium and molybdenum.
