Title (EN) ATTRITION-RESISTANT SPRAY-DRIED ZEOLITE CATALYST
(FR) CATALYSEUR ZÉOLITIQUE SÉCHÉ PAR PULVÉRISATION RÉSISTANT À L'ATTRITION
Abstract:
(EN) An attrition-resistant catalyst is prepared contacting a spray dried zeolite with a modifying agent. The modifying agent is (i) a halogen-free compound hydrolyzable to an oxide selected from the group consisting of silica, alumina, titania, zirconia, niobia, and mixtures thereof; or (ii) a sol selected from the group consisting of silica, alumina, titania, zirconia, niobia, and mixtures thereof.
(FR) Un catalyseur résistant à l'attrition est préparé par la mise en contact d'une zéolite séchée par pulvérisation avec un agent modificateur. L'agent modificateur est (i) un composé exempt d'halogène hydrolysable en un oxyde choisi dans le groupe constitué par la silice, l'alumine, le dioxyde de titane, la zircone, l'oxyde de niobium et leurs mélanges; ou (ii) un sol choisi dans le groupe constitué par la silice, l'alumine, le dioxyde de titane, la zircone, l'oxyde de niobium et leurs mélanges.
