A process is provided for separating at least one component from a mixture of components which comprises contacting the mixture with a composition comprising a functionalized inorganic, porous, non-layered crystalline phase having uniformly sized pores of at least about 13, e.g., at least about 15, Angstrom Units in diameter.
摘要:
A process for oligomerizing alpha olefins to produce hydrocarbon oligomers useful as lubricants and lubricant additives uses a catalyst comprising 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.

摘要:
There is provided a method for synthesizing a new synthetic composition of ultra-large pore crystalline material which can be used as a sorbent or catalyst component for conversion of organic and inorganic compounds. The crystalline material product of this method exhibits unusually large sorption capacity demonstrated by its benzene adsorption capacity of greater than about 15 grams benzene/100 grams at 50 torr and 25.degree. C. This material may have a hexagonal electron diffraction pattern that can be indexed with a d.sub.100 value greater than about 18 Angstrom Units and a hexagonal arrangement of uniformly sized pores with a maximum perpendicular cross section of at least about 13 Angstrom units. The reaction mixture for preparing this material is prepared by forming a solution containing a source of an oxide, followed by adding a gelling reagent to this solution to form a gel.
