    摘要: A process for dewaxing waxy hydrocarbon feedstocks to produce distillate fuels or lubricant stocks having improved pour point properties. The process comprises catalytic hydroisomerization of the feedstock over catalyst comprising a synthetic porous crystalline material characterized in its calcined form by an X-ray diffraction pattern including interplanar d-spacings at 12.36.+-.0.4, 11.03.+-.0.2, 8.83.+-.0.14, 6.18.+-.0.12, 6.00.+-.0.10, 4.06.+-.0.07, 3.91.+-.0.07 and 3.42.+-.0.06 Angstroms, and an Alpha Value of 10 or less.

    摘要: As synthesized by previous methods, ZSM-5 or ZSM-11 zeolites are crystallized in the presence of substantial amounts of a nitrogen-containing compound. When synthesized in this way, they contain an organic ammonium cation as well as a metal cation such as sodium. To obtain a more active form, the sodium ion must be exchanged out. Such exchange, especially with ZSM-5 and ZSM-11, is difficult unless there is calcination of the zeolite to remove the obstructing organo compounds. By making these zeolites in the presence of (1) seeds of the desired zeolite, (2) mixtures of them with ammonium hydroxide and/or alcohol, (3) the alcohol per se or (4) mixtures of the alcohol with ammonium hydroxide, a product substantially deficient in organic ammonium cation is obtained. These products can be exchanged directly without any calcination.
