Title (EN) HYDROCARBON UPGRADING PROCESS
(FR) PROCESSUS D'ENRICHISSEMENT DES HYDROCARBURES
Abstract:
(EN) Low sulfur gasoline is produced from an olefinic, cracked, sulfur-containing naphtha by treatment over an acidic catalyst, preferably an intermediate pore size zeolite such as ZSM-5 to crack low octane paraffins and olefins under relatively mild conditions, with limited aromatization of olefins and naphthenes. This is followed by hydrodesulfurization over a hydrotreating catalyst such as CoMo on alumina. The initial treatment over the acidic catalyst removes the olefins which would otherwise be saturated in the hydrodesulfurization, consuming hydrogen and lowering product octane, and converts them to compounds which make a positive contribution to octane. Overall liquid yield is high, typically at least 90 % or higher. Product aromatics are typically increased by no more than 25 wt.% relative to the feed and may be lower than the feed.
(FR) On produit de l'essence à faible teneur en soufre à partir d'un naphta oléfinique de craquage à base de soufre, en réalisant un traitement au-dessus d'un catalyseur acide, de préférence une zéolite de dimension des pores intermédiaire, telle que ZSM-5, pour craquer des paraffines et des oléfines à faible indice d'octane dans des conditions relativement tempérées avec une aromatisation limitée des oléfines et des naphtènes. Cette étape est suivie d'une hydrodésulfuration au-dessus d'un catalyseur d'hydrotraitement tel que CoMo sur de l'alumine. Le traitement initial au-dessus du catalyseur acide élimine les oléfines (qui seraient autrement saturées pendant l'hydrodésulfuration) en consommant l'hydrogène et en abaissant l'indice d'octane, puis les transforme en composés apportant une contribution positive à l'octane. On obtient une production totale de liquide élevée, généralement de l'ordre de 90 % au moins, voire plus. La production d'aromates est généralement accrue d'au plus 25 % en poids relativement à la charge d'alimentation, et peut être inférieure à la charge d'alimentation.
