    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 the feed to be treated is brought into contact with a catalyst. The catalyst comprises at least one dioctahedral 2:1 phyllosilicate, preferably synthesised in a fluoride medium in the presence of the acid HF and/or a further source of fluoride anions, and preferably having an interplanar spacing of at least 20×10−10 m (2 nm) and comprising pillars based on at least one oxide of elements from groups IVB, VB, VIB, VIII, IB, IIB, IIA or IVA or any combination of these oxides, and preferably selected from the group SiO2, Al2O3, TiO2, ZrO2 and V2O5, or any combination of these latter. The catalyst further comprises at least one hydrodehydrogenating element in the metallic form. The process is carried out at a temperature in the range 170° C. to 500° C., a pressure in the range 1 to 250 bar and at an hourly space velocity in the range 0.05 to 100 h−1, in the presence of hydrogen in an amount of 50 to 2000 1/1 of feed. The oils obtained have good pour points and high viscosity indices (VI). The process is also applicable to gas oils and to other feeds requiring a reduction in their pour point.

    摘要： A hydrocracking catalyst has a carrier that has particles of a compound oxide and a binder present between these particles, and at least one metal component selected from Group 6, Group 9 or Group 10 of the Periodic Table supported on the carrier. The catalyst has a median pore diameter of 40 to 100 Å and the volume of pores whose pore diameter falls within a range of 40 to 100 Å is at least 0.1 mL/g. Moreover, the volume of pores of the catalyst whose pore diameter falls within a range of 0.05 to 5 &mgr;m is 0.05 to 0.5 mL/g, and the volume of pores whose pore diameter is 0.5 to 10 &mgr;m is less than 0.05 mL/g. This catalyst is mechanically strong enough for practical use and has a high conversion rate and middle distillate selectivity in hydrocracking of hydrocarbon oils, particularly vacuum gas oil.
