This invention relates to a method for increasing thermal stability of fuel, as well as in reducing nitrogen content and/or enhancing color quality of the fuel. According to the method, a fuel feedstock can be treated with a solid phosphoric acid catalyst under appropriate catalyst conditions, e.g., to increase the thermal stability of the fuel feedstock. Preferably, the fuel feedstock can be treated with the solid phosphoric acid catalyst at a ratio of catalyst mass within a contact zone to a mass flow rate of feedstock through the zone of at least about 18 minutes to increase the thermal stability of the fuel feedstock, along with reducing nitrogen content and/or enhancing color quality.

Lubricating oils of improved initial and long term metal corrosion inhibiting properties comprises a base stock containing one or more hydrodewaxate or hydroisomerate base stock(s) and/or base oil(s), GTL base stock(s) and/or base oil(s), or mixtures thereof, preferably GTL base stock(s) and/or base oil(s), boiling in the lubricating oil boiling range and an additive amount of an anti-corrosion additive.

Method for improving the corrosion inhibiting properties of lubricant compositions

Alkoxylated fatty acid alkyl esters are produced from a bio-component feed, preferably containing triglycerides. The triglycerides can be reacted with an alcohol in the presence of an acidic catalyst to form alkoxylated fatty acid alkyl esters, which can provide improved low temperature properties and/or improved oxidative stability in petrochemical products, relative to non-alkoxylated versions of the fatty acid alkyl esters.

The resistance to oxidation and nitration of a gas engine oil is improved by the use of a combination of a hindered phenolic antioxidant and an (alkylated) phenyl-&#x3b1;-naphthylamine antioxidant. The additional use of an organo molybdenum compound further enhances the resistance to oxidation and nitration.

Haze formation in heavy Gas-to-Liquids (GTL) base stock is mitigated by the addition to said GTL base stock of one or more particular additives.

Method for haze mitigation and filterability improvement for gas-to-liquid hydroisomerized base stocks

The removal of fluoroalkanes from fluoroalkane-containing hydrocarbon streams, preferably Cto Chydrocarbon 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.

Removal of light fluoroalkanes from hydrocarbon streams

A method for improving the air release rate of a Gas-to-Liquids (GTL) base stock and/or base oil by the addition to such base stock and/or base oil of a synthetic ester.
