Title (EN) PROCESS FOR REFORMING PETROLEUM HYDROCARBON STOCKS
(FR) PROCEDE DE REFORMAGE DE MATIERES PREMIERES D'HYDROCARBURES DE PETROLE
Abstract:
(EN) Processes for reforming, and in particular aromatising, hydrocarbons from a petroleum source may be carried out by contacting the hydrocarbons with a catalyst of a zeolite KL impregnated with a metal promotor such as platinum, in which the zeolite crystals are of hockeypuck shape. The processes have a good yield and selectivity for the desired reformed products and the catalyst is stable, is associated with a low rate of coke formation, and has a long catalytically active life before regeneration is required.
(FR) On peut mettre en ÷uvre des procédés de reformage, et notamment d'aromatisation, d'hydrocarbures provenant d'une source de pétrole, par mise en contact des hydrocarbures avec un catalyseur d'une zéolite KL imprégnée d'un promoteur de métal tel que le platine, dans lequel les cristaux de la zéolite ont la forme d'un palet de hockey. Les procédés ont un bon rendement et présentent une bonne sélectivité des produits reformés voulus, le catalyseur est stable, il est associé à une vitesse lente de formation de coke et il a une vie catalytiquement active longue avant qu'une régénération ne soit nécessaire.
