A method is provided for turning down from design conditions or below the output of raw product gas from a free-flow partial oxidation gas generator, or when operating below design conditions the output of raw product gas from the gas generator may be turned up while maintaining substantially constant the efficiency of the gas generation, or conversion of the fuel to gas, and the quality of the gas produced. The flow rates of the feedstreams to the burner are adjusted down or up a predetermined ...

A lubricating oil composition containing sulfurized calcium alkylphenolate detergent dispersant of superior resistance to oxidation prepared by (1) reacting at a temperature between 200.degree. and 425.degree.F. alkylphenol with a first addition of calcium alkoxyalkoxide to form a calcium alkylphenolate containing first reaction mixture utilizing between about 45 and 90 wt. % of the stoichiometric amount required to convert the alkylphenol to calcium alkylphenolate, (2) contacting the calcium al...

A composition for imparting softness to fabrics by utilizing an aqueous dispersion of a di(secondary alkyl) ammonium sulfate or phosphate.

Separation of unreacted amines and other undesired by-products from amine-derived dispersants and additives through adsorption of the undesired amines and by-products on polyurethane foam.

A reaction product of detergent-dispersant properties in lubricating oil prepared by the sequential method of (1). reacting polyalkene of from 30 to 300 carbons with maleic anhydride to form alkenyl succinic anhydride, (2). contacting the alkenyl succinic anhydride with chlorine or bromine in the absence of hydroxylic and solvent compounds to form halogenated alkenyl succinic anhydride, (3). contacting the halogenated alkenyl succinic anhydride with alkylene polyamine to form crude reaction prod...

The reaction product from etherification of C.sub.4 -C.sub.7 isoolefins with methanol in the presence of an acidic catalyst is washed with water in the presence of inert hydrocarbons thereby removing methanol and a part of the tertiary alcohol. The aqueous extract solution bottoms is distilled to separate methanol as overhead. Tertiary alcohols are withdrawn as a side stream from a tray of the distillation column with a high concentration thereof and fed into the washing column.

The soot-water dispersion that is produced by quenching and/or scrubbing the raw effluent gas stream from a partial oxidation gas generator in a gas quench cooling and/or scrubbing zone is resolved in a decanter using two different liquid organic extractants. Advantageously, liquid organic by-products from an oxo or oxyl process which may contain harmful water soluble constituents may be used as a major portion of the liquid organic extractant. The dispersion of soot and co-extractants that is p...

Process for liquefying coal or similar liquefiable carbonaceous solids in which the liquefaction solvent is a hydrotreated solvent mixture that is derived in the process. The solvent mixture comprises at least 78 wt. % decalin, comprising cis and trans decalin. The cis-isomers comprise at least 80 wt. % of the total weight of the decalin. The solvent mixture may also include about 0-2 wt. % of naphthalene, about 0-5 wt. % of a constituent comprising the mono and/or di methyl derivative of at lea...

A motor fuel composition which inhibits engine ORI and intake valve deposit formation and sticking comprises a mixture of hydrocarbons boiling in the range of 90.degree. F.-450.degree. F. and (I) the reaction product of a hydrocarbyl-substituted dibasic acid anhydride and a polyoxyalkylene diamine; (II) a polymeric component which is a polyolefin polymer, copolymer, or the corresponding aminated or hydrogenated polymer or copolymer, or mixtures thereof, of a C.sub.2 -C.sub.10 hydrocarbon; (III) ...

An additive composition prepared by reacting a polymer prepared from ethylene and at least one C.sub.3 -C.sub.10 alpha-monoolefin and optionally a polyene selected from non-conjugated dienes and trienes comprising from about 15 to 80 mole percent of ethylene from about 20 to 85 mole percent of said C.sub.3 -C.sub.10 alpha-monoolefin and from about 0 to 15 mole percent of said polyene and having an average molecular weight ranging from about 5,000 to 500,000 with a nitrosodiphenylamine compound r...
