Patent

CA 2434746

A process is disclosed for producing hydrocarbons. The process involves contacting a feed stream comprising hydrogen and carbon monoxide with a catalyst in a reaction zone maintained at conversion-promoting conditions effective to produce an effluent stream comprising hydrocarbons. In accordance with this invention, the catalyst used in the process includes at least a Fischer-Tropsch metal and boron. The Fischer-Tropsch metal preferably includes cobalt and optionally ruthenium or platinum. The catalyst may also comprise a support material selected from the group including silica, titania, titania/alumina, zirconia, alumina, aluminum fluoride, and fluorided aluminas.

La présente invention concerne un procédé de production d'hydrocarbures. Ce procédé implique d'avoir un débit d'entrée à base d'hydrogène et de monoxyde de carbone et de l'amener au contact d'un catalyseur dans une zone de réaction maintenue dans des conditions favorisant la conversion, permettant la production d'un courant d'effluents comprenant des hydrocarbures. Selon l'invention, le catalyseur utilisé dans le processus comporte au moins un métal de Fischer-Tropsch et du bore. Le métal de Fischer-Tropsch inclut de préférence le cobalt et éventuellement le ruthénium ou le platine. Le catalyseur peut également comporter un métal support appartenant au groupe incluant la silice, l'oxyde de titane, l'oxyde double de titane et d'aluminium, la zircone, l'alumine, la fluorure d'aluminium, et les alumines fluorurées.
