Abstract: A catalytic multi-stage hydrocarbon conversion process is provided for reducing high metals content, sulfur content and pour point of the catalytically reacted residual oil by the use of sequential combination of catalytic compositions. In the first stage, the residual oil, under demetalation and desulfurization reaction conditions, is passed over a catalyst comprising about 1 to about 10 weight percent of a Group VIB metal, based on the total catalyst weight, on a supporting comprising at least 85 weight percent alumina. The resulting catalyst contains at least 65 percent of its pore volume in the 150 to 300 Angstroms diameter range or at least 60 percent of its pore volume in the 100 to 200 Angstroms diameter range.

Abstract: The pour point of a hydrocarbon charge stock boiling above about 850.degree. F., is reduced by catalytically dewaxing the charge stock in the presence of a zeolite catalyst and subsequently subjecting at least the liquid portion thereof to hydrotreating in the presence of a hydrotreating catalyst comprising a hydrogenating component and a siliceous porous crystalline material from the class of ZSM-5, ZSM-11, ZSM-23 and ZSM-35 zeolites.

Abstract: Heavy oils are simultaneously subjected to hydrocracking and dewaxing using a catalyst comprising zeolite beta and an X or Y or other faujasite zeolite together with a hydrogenation component. The process is able to effect a bulk conversion of the oil while, at the same time, yielding a low pour point product.

Abstract: A high quality lube base stock oil of low pour point and excellent stability is produced from a waxy crude oil fraction in a single-stage hydrodewaxing process by using an improved ZSM-5 type catalyst having nickel-molybdenum, cobalt-molybdenum or a molybdenum hydrogenation agent incorporated thereon.

Abstract: The pour point of a hydrocarbon charge stock boiling in the range of 400.degree. F. to 1050.degree. F., and particularly a lubricating oil charge stock boiling between 600.degree. F. and 1050.degree. F. is reduced by catalytically dewaxing the charge stock in the presence of a zeolite catalyst and subsequently subjecting at least the liquid portion thereof to hydrotreating in the presence of a hydrotreating catalyst comprising a hydrogenating component and a siliceous porous crystalline material from the class of ZSM-5, ZSM-11, ZSM-23 and ZSM-35 zeolites.

Abstract: A log splitter is formed of a vertically arranged tube, within which a metal rod is telescopically slidably fitted. The lower end of the rod is formed as a hammer block. A pointed, wedge-like tip is secured upon the lower end of the tube and has an anvil block portion that extends upwardly into the tube. Transversely extending hand grips are provided upon the upper end of the rod for manually raising and lowering the rod to impact the hammer block against the anvil block for driving the tip into a log section. A guide maintains the axial alignment of the rod within the tube and limits the travel of the rod outwardly of the tube.

Abstract: A method for enhancing both the pour point and viscosity index (V.I.) of crude oils of high wax content by contact of the same with two different zeolites, such as ZSM-5 and ZSM-35 is disclosed.

Abstract: A method is disclosed for the improvement of catalyst performance in catalytic hydrodewaxing of both petroleum and synthetic hydrocarbon feedstocks utilizing a special group of acidic crystalline aluminosilicate zeolites such as those of the ZSM-5 type which involves treatment of said zeolites in order to adjust their initially high alpha activity to within a range of 55-150 alpha prior to use as catalysts in a hydrodewaxing operation.
