    摘要: A process for transforming a gas oil cut from a conversion process or from an aromatic crude is described, the aim of the process being to improve the cetane number of said cut. The process comprises at least one hydrogenation step in which said gas oil cut is passed, in the presence of hydrogen, over a catalyst comprising an amorphous mineral support, at least one compound of a group VIB metal, at least one compound of a non noble group VIII metal and at least phosphorous or a compound of phosphorous, the process then comprising a hydrocracking step in which the hydrogenated feed is passed, in the presence of hydrogen, over a catalyst comprising an acidic support, at least one compound of a group VIB metal and at least one compound of a non noble group VIII metal.

    摘要: A process for producing oils with high viscosity indices from oil distillates or effluents from a conversion unit comprises the following steps: a) catalytic hydrotreatment of the feed in the presence of hydrogen and a non zeolitic catalyst; b) fractionation of at least a portion of the effluent from step a) or step d) described below to an oil residue; c) fractionation by thermal diffusion of at least a portion of the oil residue obtained from step b) into oil fractions with different compositions and viscosity indices. Step b) can be preceded by a step d) for hydrocracking the effluent obtained from step a) in the presence of hydrogen and a zeolitic catalyst.

    摘要: The invention concerns a process for improving the pour point of a feed comprising paraffins containing more than 10 carbon atoms, in which process the feed to be treated is brought into contact with a catalyst comprising NU-85 zeolite and at least one hydro-dehydrogenating element, at a temperature which is in the range 170.degree. C. to 500.degree. C., a pressure in the range 1 to 250 bar and an hourly space velocity in the range 0.05 to 100 h.sup.-1, in the presence of hydrogen in a proportion of 50 to 2000 l/l of feed. The oils obtained have good pour points and high viscosity indices (VI). The process is also applicable to gas oils and other feeds requiring a reduction of pour point. The invention also concerns a NU-85 zeolite from which a portion of elements T (Al, Ga, Fe or B) have been removed and which has an Si/T atomic ratio of at least 18.

    摘要: The invention concerns a process for improving the pour point of a feed comprising paraffins containing more than 10 carbon atoms, in which process the feed to be treated is brought into contact with a catalyst comprising an NU-87 zeolite comprising silicon and at least one clement T selected from the group formed by Al, Fe, Ga and B, from which at least a portion of clement T has been removed, and having a global Si/T ratio of over 20, the catalyst also containing at least one hydro-dehydrogenating element. The process is carried out at a temperature which is in the range 170.degree. C. to 500.degree. C., a pressure in the range 1 to 250 bar and at an hourly space velocity in the range 0.05 to 100 h.sup.-1, in the presence of hydrogen in a proportion of 50 to 2000 l/l of feed. The oils obtained have good pour points and high viscosity indices (VI). The process is also applicable to gas oils and other feeds requiring a reduction of pour point. The catalyst is also claimed.
