Abstract: A catalyst for oligomerizing alpha olefins to produce hydrocarbon oligomers useful as lubricants and lubricant additives comprises a supported reduced Group VIB metal, preferably chromium, in the form of its oxide. The support is a mesoporous, inorganic, crystalline solid of unique structure, of novel pore geometry. The preferred forms of these mesoporous materials are characterized by substantially uniform hexagonal honeycomb microstructure, with uniform pores having a cell diameter greater than 13 .ANG., preferably in the mesoporous range of about 20-100 .ANG.. The use of the catalysts made with the mesoporous support materials enables products of greater viscosity to be made as compared to the products from catalysts using amorphous supports. The catalyst is usually used under oligomerization conditions at a temperature of about 90.degree. to 250.degree. C. to produce liquid hydrocarbon oligomers in the lubricant range which have a branch ratio of less than 0.19 and high values of viscosity index.

Abstract: There is provided a crystalline oxide material with a characteristic X-ray diffraction pattern. This material may be a layered material, which is swollen or pillared.

However, the swollen layered material may be intercalated with polymeric oxide pillars to maintain layer separation, even after calcination.

Abstract: There is provided a process for using amphiphilic compounds in preparing new classes of crystalline oxide materials. These oxide materials may have uniformly large pores, e.g., having a size of about 40 Angstoms in diameter.
