摘要： A catalytic process is provided for converting lower monohydric alcohols and their ethers, especially methanol and dimethyl ether, to a hydrocarbon mixture rich in C.sub.2 -C.sub.3 olefins, by contact, under conversion conditions, with a catalyst comprising a crystalline aluminosilicate zeolite having a silica to alumina mole ratio of at least about 12, a constraint index, as hereinafter defined, within the approximate range of 1 to 12 and containing, in cationic form, between about 0.01 and about 1.9 milliequivalents per gram of one or more metals characterized by an ionic radius exceeding 1 Angstrom.

摘要： A method for the recovery of oil from an oil-containing subterranean formation by waterflooding employing as an injection medium an aqueous dispersion of a hydrophilic carbon oxide. According to a preferred form of the invention, particulate graphite oxide characterized by a surface layer in which the molar carbon to oxygen ratio is from about 2 to about 3 is utilized as a viscosifier to decrease the mobility ratio between the injected water and oil, thereby improving the efficiency of the waterflood. The graphite oxide may be characterized by a surface substantially free of --COOH groups, thereby being insensitive to divalent metal ions present in the subterranean formation. According to another form of the invention, the graphite oxide is reactive with the divalent metal ions within the subterranean formation to form a plugging deposit and thereby to function as a sealant for highly permeable strata within the formation.

摘要翻译： 一种通过水驱采用含水地层从油中回收油的方法，其使用亲水性碳氧化物的水分散体作为注射介质。 根据本发明的优选形式，利用特征在于碳摩尔比摩尔比为约2至约3的表面层的颗粒状氧化石墨作为增粘剂以降低注射的水和油之间的迁移率，从而 提高注水效率。 石墨氧化物的特征在于基本上不含-COOH基团的表面，因此对存在于地层中的二价金属离子不敏感。 根据本发明的另一种形式，石墨氧化物与地下地层内的二价金属离子反应形成堵塞沉积物，从而起到地层内高渗透层的密封剂的作用。

摘要： Normal paraffin alkylation with an alkylating agent, i.e. olefin, alkylhalide or alcohol, is effected in the presence of a catalyst of graphite having intercalated in the lattice thereof between about 5 and about 75 weight percent of a Lewis acid. The catalyst utilized in alkylation has additionally intercalated therein between about 0.1 and about 20 weight percent of a Group VIII metal.
