Patent

CA 2746006

The present invention relates to a hydrocarbon synthesis catalyst comprising in its unreduced form a) Fe as catalytically active metal, b) an alkali metal and/or alkaline-earth metal in an alkali metal- and/or alkaline-earth metal-containing promoter, the alkali metal, c) and a further promoter comprising, or consisting of, one or more element(s) selected from the group of boron, germanium, nitrogen, phosphorus, arsenic, antimony, sulphur, selenium and tellurium, to a process for the synthesis of a hydrocarbon synthesis catalyst, to a hydrocarbon synthesis process which is operated in the present of such a catalyst and to the use of such a catalyst in a hydrocarbon synthesis process.

La présente invention concerne un catalyseur de synthèse des hydrocarbures qui comprend, sous sa forme non réduite, a) du Fe en tant que métal catalytiquement actif, b) un métal alcalin et/ou un métal alcalino-terreux dans un promoteur contenant un métal alcalin et/ou un métal alcalino-terreux, le métal alcalin, c) et un autre promoteur comprenant, ou étant constitué par, un ou plusieurs élément(s) choisis dans le groupe constitué par le bore, le germanium, l'azote, le phosphore, l'arsenic, l'antimoine, le soufre, le sélénium et le tellurium, un procédé de synthèse d'un catalyseur de synthèse des hydrocarbures, un procédé de synthèse des hydrocarbures qui fonctionne en présence d'un tel catalyseur et l'utilisation d'un tel catalyseur dans un procédé de synthèse des hydrocarbures.
