Abstract: The present invention provides a method for purifying alkanolamine solutions which have lost at least a portion of their acid gas sorption capacity due to degradation of the alkanolamine into heat stable salts. Particularly, it has been found that the alkanolamine solution may be rejuvenated by charging the solution to the feed zone of a distillation column reactor at temperatures above about 160.degree. C. and pressure of less than about 2000 mm Hg.

Abstract: A method for disposing of drilling wastes where an aqueous saline solution is used to disperse a drilling fluid or mud. The saline solution containing the dispersed drilling fluid or mud is injected into a disposal well or high permeability oil depleted zone. An interval of the formation adjacent to the disposal well is hydraulically fractured so as to allow continued injection of the solution containing the drilling fluid or mud at substantially low pressures. Hydraulic fracturing is used to re-establish communication with a disposal zone whenever a "skin" builds up due to filtration of the solids from the injected drilling fluids or muds.

Abstract: A low acidity Group VIII metal-containing zeolite MCM-22 catalyst, said zeolite exhibiting an Alpha value of not greater than about 150, is provided for conversion of aliphatic C.sub.2 to C.sub.12 hydrocarbon(s) to olefin(s) and/or aromatic(s).

Abstract: Isopentene, or isoamylene, conversion to methyl tert-amyl ether can be substantially improved while high conversion of isobutylene to methyl tert-butyl ether can be maintained by carrying out the overall etherification process with alkanol in a staged manner, wherein the first stage is methanol etherification of a C.sub.5 +, or C.sub.5, hydrocarbon feedstream rich in isoamylene and the second stage is etherification to produce MTBE and additional TAME from a C.sub.4 +, or C.sub.4, feedstream. Unreacted methanol and hydrocarbons from the first etherification are uniquely separated by fractionation from the TAME product by using the second stage C.sub.4 + feedstream as a reflux stream to the fractionator and passed to the second etherification zone. Products from the second etherification zone are separated by distillation to produce MTBE, TAME and C.sub.5 +, or C.sub.5, hydrocarbons as a bottom stream.

Abstract: An atomizing nozzle for injecting fluid catalytic cracking (FCC) feed into a cracking riser comprises a spray nozzle for breaking up the feed to form a conical, atomized spray of feed which is confined within an open ended nozzle pipe surrounding the spray nozzle and which extends downstream from the spray nozzle. Atomizing gas, usually steam, passes around the spray nozzle to promote further atomization and vaporization of the feed and the mixture of feed droplets and atomizing gas is passed through an orifice plate at the tip of the spray nozzle pipe to expand the spray across a greater axial distance. The atomizing system provides improved feed atomization and contact with the cracking catalyst with relatively low pressure drops.

Abstract: A method for gravel packing a wellbore where a resin-coated sand or "gravel" is utilized. First, the wellbore is perforated at the productive interval in a manner sufficient to hydraulically fracture the formation. Afterwards, the formation is hydraulically fractured via a frac fluid containing a resin-coated sand. During this fracturing operation, a resultant fracture is propped with the resin-coated sand. The frac fluid is pumped down the wellbore until "screen out" occurs at perforations in the wellbore. The resin-coated sand is allowed to remain in the fracture, perforations, and wellbore until a permeable, porous consolidated mass is formed. After the mass has formed, excess consolidated sand is removed from the wellbore. When the formation is produced, formation solids are contained by the consolidated mass in the fracture and perforations.

Abstract: A process is disclosed for the production of high octane alkyl tertiary alkyl ether rich gasoline and gasoline rich in alkylated aromatics. It is disclosed that unreacted C.sub.3 -C.sub.4 hydrocarbon fraction of etherification feedstock plus unreacted alkanol can be separated and employed as alkylating agents in combination with a feedstream containing light aromatics when the alkylation reaction is carried out under conditions of high severity in contact with a high activity shape selective metallosilicate catalyst such as ZSM-5. Under high severity conditions olefin-assisted paraffin conversion also occurs as well as cracking, redistribution and alkylation. Aromatic rich gasoline is a suitable feedstream to the high severity conversion zone to produce a gasoline rich in alkylated aromatics.

Abstract: The thermal stability of poly alpha-olefin (PAO) lubricant basestocks are improved by reacting an aromatic compound with the alpha-olefin oligomer. The PAO materials are prepared by oligomerization of olefins such as 1-decene in the presence of a Lewis acid oligomerization catalyst. The resulting lubricant basestock product exhibits high viscosity, viscosity index and low pour point in addition to the unique enhancement in thermal stability. The reaction between the PAO and the aromatic is carried out in the presence of a solid, cyrstalline alkylation catalyst identified by a specific X-ray diffraction pattern. The preferred catalyst for this purpose is the material known as MCM-22.

Abstract: The process relates to converting normal paraffins and/or mono-methyl branched paraffins, which are generally of low octane value, to more highly branched isoparaffins which are generally superior to normal paraffins in octane.

Abstract: A method is provided for high temperature conversion of mercutry-containing hydrocarbon feedstocks to produce a product stream with a negligible mercury level and to protect cryogenic heat exchangers from mercury damage. The feed is treated with adsorbent at high temperatures to remove up to 99% of the mercury. After high temperature conversion, the product stream is treated over a second adsorbent composition to remove any residual mercury and water before the product is cooled and collected.

Abstract: The stability of HVI-PAO olefin oligomers is improved by reaction of the oligomer over an acidic function catalyst which introduces aromatic groups into the oligomer by cracking a portion of the oligomer to form cracking fragments which are then aromatized to aromatics which are subsequently alkylated by the oligomer. This reaction incorporates an aromatic function into the oligomer to produce a modified oligomer product of improved stability. The olefinic oligomers are prepared from 1-alkene by oligomerization in contact with a reduced metal oxide, preferably reduced chromium oxide, catalyst on support such as silica. The products retain the unique features of the olefin oligomer and exhibit high viscosity index and low pour point as well as improved thermal and oxidative stability and additive solvency characteristics resulting from the introduction of aromatic moieties into the structure of the oligomer by the intramolecular dehydrocyclization reaction.

Abstract: A process for oligomerizing alpha olefins to produce hydrocarbon oligomers useful as lubricants and lubricant additives uses a catalyst comprising a supported reduced group VIB metal, preferably chromium, in the form of its oxide. The support is a mesoporous, inorganic, crystalline solid of unique structure, of novel pore geometry. The preferred forms of these mesoporous materials are characterized by substantially uniform hexagonal honeycomb microstructure, with uniform pores having a cell diameter greater than 13 .ANG., preferably in the mesoporous range of about 20-100 .ANG.. The use of the catalysts made with the mesoporous support materials enables products of greater viscosity to be made as compared to the products from catalysts using amorphous supports. The catalyst is usually used under oligomerization conditions at a temperature of about 90.degree. to 250.degree. C. to produce liquid hydrocarbon oligomers in the lubricant range which have a branch ratio of less than 0.
