Abstract: A method for screening a candidate for efficacy as an asphaltene stabilizer comprises: forming a reconstituted oil by dispersing an asphaltene-containing solid in a hydrocarbon fluid; adding an asphaltene stabilizer candidate to the reconstituted oil to give an additized oil; and analyzing the stability of the asphaltenes in the additized oil. The method may be used to select a candidate for use as an asphaltene stabilizer during crude oil production, transportation or processing.

Abstract: The invention relates to processes for reducing the sulfur content in hydrocarbon fuels such as gasoline, diesel fuel and jet fuel. The invention provides a method and materials for producing ultra low sulfur content transportation fuels for motor vehicles as well as for applications such as fuel cells. The materials and method of the invention may be used at ambient or elevated temperatures and at ambient or elevated pressures without the need for hydrogen.

Abstract: The present invention provides a method of producing a CuZnAlZr oxide catalyst consisting of reacting an aqueous NaOH solution and aqueous Na2CO3 solution with a mixture of aqueous solutions of each nitrate of Cu, Zn, Al, and Zr, producing a precipitate by coprecipitation, aging, filtering, washing and drying this precipitate to prepare a catalyst precursor consisting of a CuZnAlZr layered double hydroxide, and then obtaining a CuZnAlZr oxide by calcining this precursor in an air ambient atmosphere, a CuZnAlZr oxide catalyst, a CuZnZrCe oxide catalyst, a CoCuZnAl oxide catalyst for producing hydrogen by oxidative steam reforming a methanol, and methods of producing hydrogen gas consisting of converting methanol to hydrogen gas by oxidative steam reforming in the presence of air and steam using these oxide catalysts.
