Abstract: Compositions of ethylene alkyl acrylate grafted onto a polyolefin such as isotactic polypropylene are provided. The composition is highly wettable by adding both a polar group material and a hydrophilic modifier to the polypropylene. The hydrophilic modifier comprises a monoglyceride and a salt of a linear alkyl. The process comprises extruding the polyolefin into a fiber which is spinnable and may be used to form woven or nonwoven materials. The composition products are particularly well suited for forming various goods, including diaper coverstock, personal hygiene pads, battery separators, filters, tea bag pouches and filter stock.

Abstract: A food grade compressor oil for use in a high pressure compressor includes a base oil, an N-acyl derivative of the amino acid sarcosine, an imidazoline, and an amine-phosphate. Each of the three additives comprises no more than 0.5% by weight of the oil composition, and results in high lubricity and very low corrosion even when water is present in the oil. The compressor oil may also include polybutene which serves as a thickener, and an antioxidant. The compressor oil of this invention is particularly well suited for use in a hypercompressor used in the manufacture of polyethylene.

Abstract: Compositions of ethylene alkyl acrylate grafted onto polypropylene are dyeable with disperse or cationic dyes. A small amount of polyester may be include, along with a hydrophilic modifier comprising a monoglyceride and a salt of a liner alkyl. The hydrophilic modifier also acts as a compatibilizer to bridge the polyester and the polypropylene. A process for dyeing polypropylene fibers comprises combining the polypropylene with a thermoplastic copolymer of ethylene and alkyl acrylates having 1 to 4 carbon atoms in the alkyl group into fibers, adding the polyester to the polypropylene matrix, spinning the composition into fibers, and exposing the fibers to a dye bath. The sulfonic group may be added to the polyester for exposing the fibers to a cationic dye.

Abstract: This invention provides a process to remove aromatic color bodies, particularly oxygen or sulfur containing aromatics from a C.sub.8-11 aromatic hydrocarbon stream having a boiling range between about 160.degree.-460.degree. F. The process involves contacting the hydrocarbon stream with a neutral attapulgite clay for a time sufficient to adsorb the aromatic color bodies. The process is effective in reducing the APHA color value of the subject hydrocarbon stream from an initial 850-1100 value to about 400 or less.

Each of the extreme pressure additive, thickener, and the one or more oil dispersible additives is essentially free of heavy metals, particularly arsenic, antimony, barium, cadmium, chromium, copper, iron, lead, mercury, molybdenum, nickel, selenium, vanadium and zinc. The greases of the present invention meet or exceed the EPA acceptance standards in effect during 1991 which are defined by the static sheen test and the 96-hour Mysidopsis bahia (shrimp) tests for offshore and inland water use.

Abstract: A process for separating or stripping lighter components from a heavier hydrocarbon feedstock contaminated with or otherwise including light components. The separation is accomplished by introducing the feedstock into a column and allowing the feedstock to flow through the column, contacting a first stripping medium and a second stripping medium. The first stripping medium entrains the lighter components. The second stripping medium entrains the first stripping medium and any lighter components remaining in the feedstock. Preferred first stripping media include hydrogen, methane, propane, and other inert gas and preferred second stripping media include nitrogen and other inert gas.

Abstract: The invention relates to a method for removing RCS from off-spec white mineral oil prepared by catalytic hydrogenation by filtering the off-spec white mineral oil through a bleaching clay, such as a smectite clay, particularly an acid treated montmorillonite clay, such as bentonite or attapulgite.

Abstract: An improved acid gas recovery system is provided which has particular application in reducing the incidence of sulfide and other acid gas excursions. The present invention addresses the disadvantages of prior absorption techniques by closely monitoring and maintaining a reaction zone temperature profile within a contactor to improve and control the reaction between acid gas components and the aqueous amine absorbent. The temperature profile is maintained by frequently adjusting relative flow rates of the feed gas and lean amine in the process which in turn reduces the incidence of excursions.

Abstract: This invention relates to a method for removing polar bodies and other contaminants, including color bodies, from unsaturated hydrocarbon streams having a boiling range between 280.degree.-310.degree. F. by contacting the unsaturated hydrocarbon stream with a neutral clay comprising an oxide state of at least one and preferably two of Si, Al, Fe, Ca, Mg, K, Na, S, and P, particularly attapulgite clay. The process is most effective if the unsaturated hydrocarbon stream is first dried using a molecular sieve.

Abstract: The invention provides a method of converting light hydrocarbons to olefins, gasoline and methanol. In the first stage, a gas containing one or more light hydrocarbons is synthesized to higher hydrocarbons including raw gasoline. However, at commercially acceptable selectivities using currently available catalyst, a majority of the light hydrocarbons remain unsynthesized. In addition, the synthesis produces significant quantities of carbon dioxide and some carbon monoxide. In this method the unsynthesized light hydrocarbons and the oxides of carbon are used to produce methanol, which can be used for several purposes including gasoline or ethylene synthesis.
