PROCESS FOR THE PREPARATION OF METHANE IN THE PRESENCE OF A THIORESISTANT CATALYST, AND CATALYST TO BE USED IN SUCH A PROCESS

摘要

A method of methane production with a thioresistant catalyst wherein a mixture comprising in particular carbon monoxide, hydrogen and sulphur compounds is contacted with a thioresistant catalyst comprising a metal selected from the group comprising molybdenum, vanadium or tungsten and possibly cobalt and/or nickel, this catalyst being deposited onto a cerium oxide support, the reaction being performed at a temperature lying between about 250 DEG C. and 650 DEG C. and at a pressure lying between about 5 bars and 140 bars. This method is useful to carry out the effective methane synthesis with a much improved selectivity in favor of methane.
