SOLID CATALYST FOR HYDRIDE ISOMERIZATION REACTION IN AN AQUEOUS MEDIUM

A novel catalyst capable of selectively catalyzing conversion from glucose to fructose in water or in an aqueous solution is provided. The catalyst is a solid catalyst for a hydride isomerization reaction from glucose to fructose performed in water or in an aqueous solution, comprising a group 13 element oxide whose surface has been subjected to a phosphoric acid treatment.

Process to convert light alkanes to diesel

Various embodiments of a process for converting light alkanes to diesel are disclosed. In general, the process includes reacting a feed rich in one or more light alkanes with an aromatization catalyst to convert the light alkanes to aromatic hydrocarbons, reacting the aromatic hydrocarbons with a hydroalkylation catalyst to convert the aromatic hydrocarbons into diesel range hydrocarbons, and hydrogenating the diesel range hydrocarbons to produce a diesel product.
