Title (EN) CATALYSTS USEFUL FOR THE ALKYLATION OF AROMATIC HYDROCARBONS
(FR) CATALYSEURS UTILISABLES EN VUE DE L'ALKYLATION D'HYDROCARBURES AROMATIQUES
Abstract:
(EN) A catalyst useful for the alkylation or transalkylation of aromatic compounds is disclosed. The catalyst is an acid-treated zeolitic catalyst produced by a process including contacting an acidic zeolitic catalyst comprising surface non-framework aluminum and framework aluminum with an organic dibasic acid at a catalyst to acid weight ratio in the range from about 2:1 to about 20:1 and at a temperature in the range from about 50°C to about 100°C to selectively remove at least a portion of the surface non-framework aluminum. The resulting catalyst may have a measured first-order rate constant, kcum, for the alkylation of benzene with propylene to form cumene, of at least 2.0 cm3/s g.
(FR) La présente invention concerne un catalyseur utilisable en vue de l'alkylation ou de la transalkylation de composés aromatiques. Ledit catalyseur est un catalyseur zéolitique traité à l'acide, obtenu par un procédé comprenant une étape consistant à mettre en contact un catalyseur zéolitique acide, comprenant de l'aluminium de charpente et de l'aluminium non de charpente en surface, avec un acide dibasique organique, et ce en respectant un rapport pondéral entre le catalyseur et l'acide se situant dans un intervalle d'environ 2 à 1 à environ 20 à 1 et à une température variant d'environ 50 à environ 100 °C, afin d'éliminer de façon sélective au moins une partie de l'aluminium non de charpente présent en surface. Le catalyseur résultant peut présenter une constante de vitesse de premier ordre, kcum, pour l'alkylation du benzène faisant appel au propylène et donnant du cumène, au moins égale à 2,0 cm3/s g.
