Title (EN) PRODUCTION OF LOW SULPHUR ALKYLATE GASOLINE FUEL
(FR) PRODUCTION D'ESSENCE ALKYLAT À FAIBLE TENEUR EN SOUFRE
Abstract: front page image
(EN)A method for producing a low sulphur containing fuel from a hydrocarbon feed having from 10 to 80 ppm of sulphur is disclosed. The method comprises contacting a hydrocarbon stream comprising at least one olefin having from 2 to 6 carbon atoms and at least one paraffin having from 4 to 6 carbon atoms with an ionic liquid catalyst and a halide containing additive in an alkylation reaction zone under alkylating conditions to produce a fuel having sulphur content up to 10 ppm.
(FR)L'invention porte sur un procédé de production d'un carburant à faible teneur en soufre à partir d'une alimentation d'hydrocarbures ayant de 10 à 80 ppm de soufre. Le procédé consiste à mettre en contact un courant d'hydrocarbures comportant au moins une oléfine ayant de 2 à 6 atomes de carbone et au moins une paraffine ayant de 4 à 6 atomes de carbone avec un catalyseur liquide ionique et un additif contenant un halogénure dans une zone de réaction d'alkylation dans des conditions d'alkylation pour produire un carburant ayant une teneur en soufre allant jusqu'à 10 ppm.
