    摘要: Processes for reforming, and in particular aromatising, hydrocarbons from a petroleum source may be carried out by contacting the hydrocarbons with a catalyst of a zeolite KL impregnated with a metal promotor such as platinum, in which the zeolite crystals are of hockeypuck shape. The processes have a good yield and selectivity for the desired reformed products and the catalyst is stable, is associated with a low rate of coke formation, and has a long catalytically active life before regeneration is required.

    摘要: Waxy feeds are treated under hydroisomerization conditions to produce good yields of an isomerate product of high VI by using a silica-alumina based catalyst in which the silica-alumina has a pore volume less of 0.99 ml/gm (H2O), an alumina content in the range of 35 to 55 wt % and an isoelectric point in the range of 4.5 to 6.5. A lube fraction of the isomerate is dewaxed to provide a lube basestock of high VI. The silica-alumina may be modified with a rare earth oxide or yttria or boria or magnesia in which instance the modified catalyst has an isoelectric point greater than but no more than 2 points greater than base the silica-alumina.
