    摘要： Petroleum wax feeds are converted to high Viscosity Index lubricants by a two-step hydrocracking-hydroisomerization process in which the wax feed is initially subjected to hydrocracking under mild conditions with a conversion to non-lube range products of no more than about 30 weight percent of the feed. The hydrocracking is carried out at a hydrogen pressure of at least 1000 psig using an amorphous catalyst which preferentially removes the aromatic components present in the initial feed. The hydrocracked effluent is then subjected to hydroisomerization in a second step using a low acidity dicarboxylic acid-treated zeolite Beta or mordenite catalyst which effects a preferential isomerization on the paraffin components to less waxy, high V.I. isoparaffins. The second stage may be operated at high pressure by cascading the first stage product into the second stage or at a lower pressure, typically from 200 to 1000 psig. The second stage catalyst is preferably a noble metal containing zeolite Beta catalyst which is treated with oxalic acid to give a low Alpha Value, typically below 10. The second stage is carried out at relatively low temperature, typically from 600.degree. to 650.degree. F. with a 650.degree. F.+ conversion in the range of 10 to 20 weight percent of the second stage feed but with high selectivity for isomerization of the paraffins. A final dewaxing step to target pour point may be used with relatively low loss, typically no more than 15 weight percent, during this dewaxing. The final products typically have V.I. values in excess of 130 and usually in the range of 140 to 155 and are characterized by exceptional stability.

    摘要： Hydroprocessing catalysts of high metal content and surface area are based on a support material comprising a non-layered, ultra-large pore crystalline material. The crystalline material exhibits unusually large pores of at least 13 .ANG. diameter and a high sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C. and may be characterized by an X-ray diffraction pattern with at least one d-spacing greater than about 18 .ANG.. In a particularly preferred form, the crystalline material has a hexagonal arrangement of pores of at least 13 .ANG. diameter which has an electron diffraction pattern with one line at a d.sub.100 value greater than about 18 .ANG.. The catalysts based on these materials are capable of accommodating high metal loadings while retaining a high surface area with high pore volume and low density. Because of the high surface area of the support material, the metals may be incorporated by simple impregnation in a single step. The catalysts are particularly useful for process applications requiring high hydrogenation functionality and acidic functionality and therefore are useful in hydrocracking applications without requiring a halogen promoter.
