Title
(EN) SHAPE-SELECTIVE HYDROCARBON CONVERSION PROCESS
(FR) PROCEDE DE TRANSFORMATION SELECTIVE DE FORME DESTINE AUX HYDROCARBURES
Abstract
(EN)
A process for shape-selective hydrocarbon conversion involves initially contacting a feedstream, which includes an alkylaromatic compound and a co-feed of water, under conversion conditions with a catalytic molecular sieve. Preferably, the catalytic molecular sieve has been modified by being $i(ex situ) selectivated with a silicon compound. After an effective amount of time, the water co-feed is omitted from the feedstream and the hydrocarbon conversion process is continued.
(FR)
Un procédé de transformation sélective de forme destiné aux hydrocarbures comporte la mise en contact initiale d'un courant d'alimentation, contenant un composé alkylaromatique et d'une co-alimentation en eau, dans des conditions permettant la transformation, avec un tamis moléculaire catalytique. De préférence, ce dernier a été modifié en étant rendu sélectif $i(ex situ) à l'aide d'un composé à base de silicium. Une fois le temps nécessaire écoulé, on élimine la co-alimentation en eau du courant d'alimentation et on poursuit le procédé de transformation des hydrocarbures.
