Abstract: The present invention is directed to a method for hydroprocessing Fischer-Tropsch products. The invention in particular relates to an integrated method for producing liquid fuels from a hydrocarbon stream provided by Fischer-Tropsch synthesis. The method involves separating the Fischer-Tropsch products into a light fraction (FT condensate) and a heavy fraction. The heavy fraction is subjected to hydrocracking conditions, preferably through multiple catalyst beds, to reduce the chain length. The products of the hydrocracking reaction following the last catalyst bed are subjected to a separation step. The lighter material is combined with the Fischer-Tropsch condensate and hydrotreated. The hydrotreatment conditions hydrogenate double bonds, reduce oxygenates to paraffins, and desulfurize and denitrify the products. The heavier material from the separation step is sent to the lube plant for hydroisomerization, or is subjected to subsequent fraction steps to produce fuels and middle distillates.

Abstract: The drum pedal stabilizer is designed to eliminate the problems of beater dropout, pedal and beater oscillation, drum head retrigger, tempo influence and jitter feel on drum pedals and beaters. Specifically, the present invention is directed to a stabilizer having a mounting plate and a gas spring adapted for attachment to a drum pedal to counteract oscillation of the conventional helical spring. The stabilizer may be an aftermarket attachment to conventional drum pedals, or may be incorporated as original equipment in new drum pedal assemblies.

Abstract: An improved "magnetic hook"-promoted catalytic process, catalyst and method of manufacture for heavy hydrocarbon conversion, optionally in the presence of nickel and vanadium on the catalyst and in the feed stock to produce lighter molecular weight fractions, including more gasoline, lower olefins and higher isobutane than normally produced. This process is based on the discovery that two "magnetic hook" elements, namely manganese and chromium, previously employed as magnetic enhancement agents to facilitate removal of old catalyst, or to selectively retain expensive catalysts, can also themselves function as selective cracking catalysts, particularly when operating on feeds containing significant amounts of nickel and vanadium, and especially where economics require operating with high nickel- and vanadium-contaminated and containing catalysts. Under such conditions, these promoted catalysts are more hydrogen and coke selective, have greater activity, and maintain that activity and superior selectivity in the presence of large amounts of contaminant metal, while also making more gasoline at a given conversion.

Abstract: The catalytic properties of a metal-containing shape selective crystalline silicate zeolite are significantly improved by converting said metal to an intermetallic compound. Thus, for example, zeolite beta containing the intermetallic component platinum zeolite demonstrates improved catalytic properties for dewaxing a hydrocarbon feedstock compared to zeolite beta containing platinum metal alone.

Abstract: The invention is a method for cracking heavy oils to olefins. In parallel streams, the heavy stream and a steam diluent are heated to the point of partial thermal cracking while in the other stream a lighter oil and steam are cracked to produce olefins. The hot, olefinic light stream is then mixed with the heated heavy stream and further cracked. The hot, olefinic stream acts as both a diluent and a heat source for cracking the heavy oil to an olefin containing product.
