Process for the synthesis of hydrocarbons from synthesis gases in the presence of a cobalt-based catalyst

摘要

A mixture of essentially linear and saturated hydrocarbons containing at least 80% by weight C5<+> hydrocarbons, relative to all the hydrocarbons formed, is produced from a mixture constituted by hydrogen and oxides of carbon, in the presence of a cobalt-containing catalyst, molybdenum and/or tungsten and at least one additional element N from group Ib and the platinum group in which the cobalt, the molybdenum and/or tungsten and the N element(s) are dispersed on a support. The catalyst may also comprise at least one additional element from groups Ia, IIa and the lanthanide-actinide groups.
