Patent

CA 2335347

A method is provided for manufacturing cleaner fuels, in which NPC (Natural Polar Compounds), naturally existing in small quantities within various petrolic hydrocarbon fractions, are removed from the petrolic hydrocarbon fractions ranging, in boiling point, from 110 to 560 ~C and preferably from 200 to 400 ~C, in advance of catalytic hydroprocessing. The removal of NPC improves the efficiency of the catalytic process and produces environment- friendly products, such as diesel fuel with a sulfur content of 50 ppm (wt) or lower. Also the NPC can be used to improve fuel lubricity.

Procédé servant à produire des carburants plus propres et consistant à extraire les composés polaires naturels (NPC) existant naturellement en petites quantités dans différentes fractions d'hydrocarbures pétroliers hors desdites fractions dont le point d'ébullition est situé dans une plage de 110 à 560 ·C, de préférence, de 200 à 400 ·C, avant l'hydrotraitement catalytique. L'extraction de ces composés polaires permet d'améliorer l'efficacité du traitement catalytique et d'obtenir des produits sans danger pour l'environnement, tels que du carburant diesel possédant une teneur en soufre égale ou inférieure à 50 ppm en poids. On peut également utiliser ces composés polaires naturels afin d'améliorer le pouvoir lubrifiant du carburant.
