A process of modifying a zeolite catalyst to produce a modified zeolite catalyst wherein the modified zeolite catalyst has blocked pore sites. An oxygenated feed is flowed over the modified zeolite catalyst, wherein the oxygenated feed comprises hydrocarbons, methanol and dimethyl ether or a mixture thereof. The hydrocarbons, methanol and dimethyl ether in the oxygenated feed react with the modified zeolite catalyst to produce cyclic hydrocarbons, wherein the cyclic hydrocarbons produced has less than 10% durene and a median carbon number is C8.
Cette invention concerne un procédé permettant de modifier un catalyseur de zéolithe et d'obtenir un catalyseur de zéolithe modifié, ledit catalyseur de zéolithe modifié ayant des sites de pores bloqués. Une charge oxygénée, constituée dhydrocarbures, de méthanol et d'éther diméthylique ou dun mélange de ceux-ci, est déversée sur le catalyseur de zéolithe modifié. Les hydrocarbures, le méthanol et l'éther diméthylique contenus dans la charge oxygénée réagissent avec le catalyseur de zéolithe modifié pour produire des hydrocarbures cycliques, les hydrocarbures cycliques produits contenant moins de 10 % de durène et un nombre d'atomes de carbone médian de C8.
