Patent

CA 2184470

There is provided a process for increasing the Cetane Index of a distillate fraction by reacting the fraction with hydrogen over a catalyst comprising a hydrogenation component, such as platinum, and steamed zeolite Beta. The process results in the selective ring opening of cyclic compounds, such as aromatics, with a minimum of cracking of paraffinic hydrocarbons.

Procédé d'augmentation de l'indice de cétane d'une fraction de distillat qui consiste à mettre ladite fraction en réaction avec de l'hydrogène sur un catalyseur comprenant un élément d'hydrogénation, tel que du platine, et de la zéolite bêta sous forme de vapeur. Ce procédé entraîne l'ouverture sélective d'anneaux de composés cycliques, tels que des composés aromatiques, avec un minimum de craquage des hydrocarbures paraffiniques.
