摘要: A hydrocracking process is provided comprising contacting a hydrocarbon stream under hydrocracking conditions and in the presence of hydrogen with a catalyst composition which comprises a synthetic porous crystalline zeolite having a particular X-ray diffraction pattern. An embodiment of the invention provides a process for reducing the pour point of a waxy component-containing hydrocarbon oil by hydrocracking and dewaxing. Another embodiment of the invention provides a dual-stage hydrocracking process to produce premium gasoline and distillate boiling range products.

摘要: A catalytic hydrocracking process for use in refining various petroleum based feedstocks to lighter hydrocarbons. The hydrocracking process for treatment of petroleum fractions utilizes a catalyst comprising (a) a layered metal oxide of the titanometallate type intercalated with an interspathic polymeric chalcogenide, e.g., polymeric silica, (b) a transition hydrogenation metal selected from Group IVA, VIA, and VIIIA of the Periodic Table such as platinum and the like, and optionally, (c) a conventional cracking component, e.g., a large pore crystalline silicate component.

摘要: A gasket retention system and flange coupling has a ring gasket that disposes in seal seats on opposing flanges. One or more retainer tabs extend from an outer periphery of the ring gasket. Preferably, the ring gasket defines a slot on the outer periphery, and the retainer tab affixes with an interference fit in the slot to be held therein. The retainer tab defines a transverse opening therethrough. When the ring gasket fits into the seal seat of one of the flanges, the transverse opening of the tab fits onto a fastener affixed in a pre-drilled hole in the face of the flange.
