PROCESS FOR PRODUCING A DIESEL FUEL STOCK FROM BITUMEN AND SYNTHESIS GAS

A process for producing a diesel fuel stock from bitumen uses steam, naphtha and a hydroisomerized diesel fraction produced by a gas conversion process, to respectively (i) stimulate the bitumen production, (ii) dilute it for pipeline transport to an upgrading facility, and (iii) increase the cetane...

Zusammenfassung:	A process for producing a diesel fuel stock from bitumen uses steam, naphtha and a hydroisomerized diesel fraction produced by a gas conversion process, to respectively (i) stimulate the bitumen production, (ii) dilute it for pipeline transport to an upgrading facility, and (iii) increase the cetane number of a hydrotreated diesel fuel fraction produced by upgrading the bitumen by blending it with the hydroisomerized gas conversion diesel fraction, to form the diesel stock. This diesel stock has a higher cetane number than that produced from the bitumen alone, and is used for blending and forming diesel fuel. L'invention concerne un procédé permettant la production d'une matière première de carburant diesel à partir de bitume. Ce procédé comprend l'utilisation de vapeur, de naphta et d'une fraction diesel hydroisomérisée produite par un procédé de conversion gazeuse, qui permettent respectivement de (i) stimuler la production de bitume, (ii) le diluer pour permettre son transport à travers un pipeline vers une installation de valorisation, et (iii) augmenter l'indice de cétane d'une fraction du carburant diesel hydrotraité qu'on obtient par une procédure d'amélioration du bitume consitant à le mélanger à la fraction hydroisomérisée produit par conversion gazeuse afin de former l'huile de base diesel. Cette huile de base diesel présente un indice de cétane supérieur à celui obtenu avec le bitume seul, et sert au mélange et à la production de carburant diesel.
