摘要： Heavy hydrocarbon oils of high paraffin content are catalytically cracked using zeolite beta. The paraffin content of the oil is at least 20 weight percent or higher. The gasoline cracking products have a high octane rating and the higher boiling products a decreased pour point resulting from the dewaxing activity of the zeolite beta. The use of cracking temperatures above 500.degree. C., preferably above 550.degree. C., also improves iso-butene production.

摘要： A catalytic cracking process is described in which methanol is a coreactant with gas oil in combination with a small amount (catalyst/oil 0.01) of a dispersed, very fine, and highly active catalyst powder, such as ZSM-5B. The methanol is preferably admixed with the catalyst before admixture with the oil in order to protect the catalyst from adsorption of poisonous compounds (e.g., nitrogenous compounds) during the initial stages of the reaction, particularly if the methanol is insoluble in a non-polar hydrocarbon feed. The premixed materials are fed into a riser reactor. The residence time in the reactor is 6-15 seconds. Preferably, the catalyst is not regenerated. The quantity of methanol is maintained so that its exothermic reaction is approximately heat balanced with the endothermic catalytic cracking reaction.

摘要： Dewaxing a waxy feedstock is achieved by submerging the dewaxing catalyst bed in the waxy feedstock and removing gaseous products out of contact with the catalyst by agitating the bed to prevent further cracking or polymerization. Catalyst aging during dewaxing is significantly reduced by operating the dewaxing reactor within a narrow low temperature range.

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.
