摘要:
The deposit forming tendency of Group II, III and IV lubricating base oils is reduced by the use of synergistic mixtures of diphenylamines or phenyl-α-naphthylamines with triarylphosphites.
摘要:
A lubricant composition for improving electrical properties in lubricant systems to reduce the formation of sludge and varnish is disclosed. The lubricant composition comprises a base oil and an effective amount of antistatic additive to provide the composition with an electrical conductivity of at least about 50 pS/m at 25° C. and a dielectric strength of at least 300 V/mil.

摘要:
This invention relates to process for increasing color quality and thermal stability of fuel. Fuel that is provided as a feedstock is contacted or treated with an acidic, ion-exchange resin to increase the color quality and stability of the fuel. The process provides the benefit of substantially increasing the long term quality of both color and oxidation (JFTOT) stability.
摘要:
The removal of fluoroalkanes from fluoroalkane-containing hydrocarbon streams, preferably C3 to C5 hydrocarbon streams. The fluoroalkane-containing hydrocarbon stream is contacted with an adsorbent containing a strong acid function, preferably a silica gel or a strong cation ion-exchange resin having sulfonic acid functionality.
摘要:
The pour point of a lubricating composition consisting essentially of from about 5 wt % to about 100 wt % of a Group III base stock and from 0 wt % to about 95 wt % of a Group IV base stock is reduced by incorporating in the lubricating composition an effective amount of a polyol ester represented by Formula I wherein x=OH or CH2OH; y=H, CH3, CH3CH2, or CH2OH; and R1 is an aliphatic hydrocarbyl group having from about 16 to about 30 carbon atoms.
摘要:
A distillate fuel composition for reducing nickel corrosion in internal combustion engine by contaminants in the motor fuel such as sulfuric acid, alkyl sulfate esters, comprising a motor fuel and a combination of at least one 2,5 dihydrocarbyldithio-1,3,4 thiadiazole of the formula ##STR1## wherein R.sub.1 and R.sub.2 are independently H or R.sub.3 S, where R.sub.3 is a hydrocarbyl group containing from 1 to 16 carbon atoms with the proviso that at least one of R.sub.1 and R.sub.2 is not hydrogen, and an adduct of benzotriazole or tolyltriazole and an amine.
摘要:
A road asphalt composition having a penetration at 25.degree. C. in the range of 85 to 100 is made by blending together: (a) a pitch having an initial boiling point of at least 520.degree. C. obtained as a residue in the visbreaking of crude oil, and (b) a distillation residue having a penetration at 25.degree. C. in the range of 150 to 500 obtained in the distillation of crude oil.
摘要:
A process for breaking oil-in-water emulsions formed during recovery of bitumen or heavy oil. It comprises contacting the emulsion with a high ash particulate agent selected from high ash coal rejects, fly ash from coking gas and red mud from the production of alumina.
