    摘要: A process for producing high quality lubricants by the hydrocracking and hydroisomerization of petroleum waxes uses a catalyst which is based on an 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. The crystalline material is characterized by an X-ray diffraction pattern with at least one d-spacing greater than about 18 .ANG. and in a particularly preferred form, a hexagonal arrangement of pores of at least 13 .ANG. diameter which can be indexed with a d.sub.100 value greater than about 18 .ANG.. The hydrocracking catalysts based on these materials are capable of producing lube products with a high VI of at least 120 and usually higher, values of 135 and higher e.g. 143. the lube products are produced in good yield from feeds which may contain down to about 30 percent wax content, although wax contents of at least 50 percent are preferred for the highest quality products. The catalysts achieve this result without the use of fluorine or other promoters.

    摘要: Low acidity refractory oxide-bound molecular sieve, e.g., zeolite, compositions, for example, zirconia-bound zeolite Beta, possessing superior physical properties, e.g., crush strength, and the method for their manufacture are described. Since low acidity refractory oxide-bound catalysts are less active than alumina-bound zeolite catalysts, the former are particularly useful in hydrocarbon conversion processes in which reduced coke make increases catalyst cycle length. Due to their stability in acid environments, the low acidity refractory oxide-bound molecular sieve extrudate herein can be acid treated without unduly compromising its structural integrity.

    摘要: There is provided a method for preparing a zeolite other than ZSM-5 from a reaction mixture comprising a mixed organic directing agent which is a combination of (a) an organic nitrogen containing compound such as an amine or a quaternary ammonium compound and (b) an alcohol and/or diol. Particular zeolites synthesized by this method include ZSM-22 and ZSM-23. The use of an alcohol or a diol may inhibit the coformation of ZSM-5. Especially when used to prepare ZSM-23, this method enables the preparation of more catalytically active ZSM-23 of reduced crystallite size and also enables the use of lower crystallization temperatures. Particular mixed organic directing agents for the preparation of ZSM-23 are combinations of (a) pyrrolidine and (b) ethanol or ethylene glycol. Other factors which enhance the activity of ZSM-23 include the use of the following in the reaction mixtures for preparing ZSM-23: potassium ions; precipitated silica particles as sources of silica; and spray dried precipitated silica/alumina particles as sources of silica and alumina. The catalytic stability of alumina bound ZSM-23 catalysts is especially enhanced by steaming. Particular reactions which can be catalyzed by ZSM-23 made according to methods described herein include the dealkylation of ethylbenzene and the alkylation of benzene with ethylene.
