Abstract: Apparatus and method for removing particulate impurities from a fluid stream flowing into a bed of discrete solid elements, such as a bed of catalyst particles. An improved basket design is provided which maximizes the use of the bed and the mesh area of the basket to remove the particulate impurities in such a manner that the cycle life of the bed of catalyst particles or the like is extended.

Abstract: A process for upgrading a hydrocarbon fraction by contacting the hydrocarbon fraction with a dense-water-containing fluid at a temperature in the range of from about 600.degree. F. to about 900.degree. F. in the absence of an externally supplied catalyst and hydrogen and of pretreatment of the hydrocarbon fraction.

Abstract: A combination process is provided for residua demetalation and desulfurization and resulting coke gasification which comprises contacting said residua with a porous refractory oxide in the absence of added hydrogen, at a temperature of from greater than 700.degree.F to about 1100.degree.F and a refractory oxide to oil weight ratio of from about 0.1 to about 5 to produce upgraded residua of cracking feed quality, and contacting said refractory oxide after an amount of coke has formed thereon with steam and a free oxygen containing gas in which the mole ratio of steam to oxygen is from about 3 to about 5, at a temperature of from about 1000.degree.F to about 1500.degree.F to produce producer gas and regenerated porous refractory oxide for further contacting with residua.

Abstract: A method of negating the effects of metals poisoning on a cracking catalyst which comprises contacting the catalyst containing metal contaminants with a bismuth or manganese compound.

Abstract: A refinery process is described for converting desalted full range crude oils and syncrudes derived from coal, shale and tar sands. The process involves mixing and reacting the full range heavy oil feed with a low molecular weight carbon-hydrogen fragment contributor such as methanol or C.sub.2 -C.sub.5 olefins in the presence of a fluid zeolite cracking catalyst comprising mordenite.

Abstract: Heavy hydrocarbon feeds are dispersed in solvent ethers and product recycle fraction prior to catalytic cracking thereof with acidic compositions comprising particular crystalline zeolite catalyst composition. The solvent ethers are provided by reacting process olefins with methanol to produce low and high molecular weight ethers separately.

Abstract: A process for upgrading a hydrocarbon fraction by contacting the hydrocarbon fraction with a dense-water-containing fluid at a temperature in the range of from about 600.degree.F. to about 900.degree.F. in the absence of externally supplied hydrogen and of pretreatment of the hydrocarbon fraction and in the presence of a sulfur-resistant catalyst.

Abstract: The cracking of high metals content feedstocks is achieved in the presence of a catalyst comprising from 1 to 40 weight percent of a zeolite having cracking activity dispersed in a large pored matrix.

Abstract: A novel use for sorbents involving the selective removal of heavy metals from liquid streams has been discovered. More specifically it has been discovered that these sorbents selectively remove alkyl lead moieties from gasoline. The sorbents are comprised of metal halides (preferably tin tetrachloride or antimony pentachloride) bonded to a suitable substrate through at least one amine or alkyl halide functional group. The sorbents can be effectively regenerated.
