Abstract: A method is disclosed for the conversion of synthesis gas to a liquid hydrocarbon product having a boiling point range maximum of less than 400.degree. F. at a 90% overhead and being a predominantly olefinic product. The novel method involves contacting synthesis gas with a single particle catalyst containing cobalt, a crystalline acidic aluminosilicate zeolite having a silica-to-alumina ratio of at least 12, a pore size greater than about 5 Angstrom units, and a constraint index of about 1 to 12, and a siliceous matrix. The catalyst does not contain promoters and the alumina content of the matrix is severely restricted.

Abstract: A method is disclosed for the conversion of synthesis gas to a liquid hydrocarbon product having a boiling range of less than 400.degree. F. at a 90% overhead and containing approximately 5-25% of an aromatic product. The novel method involves contacting synthesis gas with a single particle catalyst containing iron, a crystalline acidic aluminosilicate zeolite having a silica-to-alumina ratio of at least 12, a pore size greater than about 5 Angstrom units, and a constraint index of about 1 to 12, and a siliceous matrix. The catalyst does not contain promoters and the alumina content of the matrix is limited.

Abstract: An improved process is provided for catalytic isomerization of monocyclic methyl-substituted aromatic hydrocarbon compounds of from 8 to 10 carbon atoms contained in a feedstock also containing ethylbenzene in a reaction zone maintained under conditions such that said isomerization is accomplished in the vapor phase. The catalyst for the process contains zeolite characterized by a constraint index, hereinafter defined, within the approximate range of 1 to 12. The improvement in the process comprises contacting the catalyst, in situ, with one or more basic nitrogen compounds or precursors thereof.

Abstract: Additives that are useful dispersants when placed in lubricants are prepared by (1) reacting an amine or a hydroxy amino compound, such as an amino alcohol, with a halomaleic anhydride and (2) reacting this product with an alkali or alkaline earth metal derivative of a substituted hydroxyaromatic compound.

Abstract: Naphthas are upgraded in a two-stage process to give improved yields of high octane gasoline. The first stage operates at low temperatures of 100.degree.-300.degree. F using a highly active chlorinated alumina containing a metal of the platinum group, while the second stage operates at high temperatures using a reforming catalyst.

Abstract: Organic compositions, particularly lubricating compositions in the form of lubricating oils and greases, are provided, containing, as antioxidants, alkali metal arylcarbamates.

Abstract: The trace lead content of gasoline, specifically in lead concentrations of about 0.01 to 0.10 grams of lead per U.S. gallon of gasoline, is determined colorimetrically by the steps of mixing an iodine solution with the gasoline, subjecting the mixture to ultra-violet light and adding an indicator solution containing 4-(2-pyridylazo)-resorcinol disodium salt with agitation and comparing the resulting color to standard indicator solutions.

Abstract: Oxidation catalysts containing platinum or other noble metal components used in automobile exhaust emission control are reactivated, after thermal deactivation, by subjecting the catalyst to a halogen-containing gas at a temperature of from 500.degree.F. to about 1000.degree.F. The passing of carbonyl halide or a mixture of carbon monoxide and halogen, alone or in a carrier gas, over the catalyst reduces the CO-oxidation and hydrocarbon-oxidation temperature to almost that of fresh catalyst. Carbonyl chloride or the carbon monoxide-chlorine mixture is preferred. This treatment may also be used in the reactivation of noble metal-containing reforming catalysts.

Abstract: Multiple metal complexes of nitrogen compounds are prepared by reacting in any desired order (1) an organic reactant, preferably an alkenylsuccinic acid or anhydride or a polyalkylphenol-aldehyde reaction mixture, or a halogenated polyolefin; (2) a polyamine, having one nitrogen atom reactive with the organic reactant and at least one additional nitrogen atom such as an ethylene polyamine and the imidazoline or imidazolidine derivative thereof; (3) and at least two metal compounds, one of which is a metal of Groups IB, IIB, IVA, IVB, VIB, VIIB or VIII of the Periodic Table, capable of both forming a coordinated complex of the Werner type with the polyamine and also forming a complex with the second metal compound, and the said metal compound of metals of the above groups plus alkali and alkaline earth metals. The reactants may be reacted in any order, such as the above order, or the amine reactant may be precomplexed.

Abstract: Alkyl lactone esters or sulfidic esters are prepared by reacting an alkenylsuccinic anhydride with an alcohol or thiol in the presence of an acid-acting catalyst. The esters are useful as dispersants or detergents in aqueous or hydrocarbon systems or they may be further reacted with amines to produce other useful additives for such systems. Esters of monohydroxy alcohols or monothiols or polyhydroxy alcohols or polythiols may be prepared and used in this invention.
