    摘要: A new family of crystalline aluminosilicate zeolites has been synthesized. These zeolites are represented by the empirical formula. Mmn+Rr+Al(1-x)ExSivOz where M represents a combination of potassium and sodium exchangeable cations, R is a singly charged organoammonium cation such as the choline cation and E is a framework element such as gallium. These zeolites are similar to MCM-68 but are characterized by unique x-ray diffraction patterns and compositions and have catalytic properties for carrying out various hydrocarbon conversion processes.

    摘要: The subject process obtains a high yield of high-purity para-xylene from 2,4,4-trimethylpentene as contained in butene dimer. A process combination may include dimerization of the isobutene to obtain C8 iso-olefins and isoparaffins, aromatization of the dimerized C8 product, and recovery of high-purity para-xylene from the dimerized product by low-intensity crystallization. Aromatization is effected using a catalyst comprising a large-pore molecular sieve. Each of the processing steps may be tailored to the overall objective of high para-xylene yield from a relatively inexpensive feedstock.

    摘要: The alkylation of aromatic compound with acyclic mono-olefin is effected at low aromatic compound to mono-olefin ratios with reduced co-production of heavies. In the processes a small crystal, acidic FAU molecular sieve is used as a catalyst under alkylation conditions. This invention also relates to catalysts containing small crystal, acidic FAU molecular sieve and at least one other acidic catalytic component.
