Abstract: The invention involves the oligomerization of olefins using a catalyst comprising a composite structure of multiple phases, at least two of which are inorganic crystalline compositions that are contiguous and have a common crystal framework and structure, and at least one of them contains phosphorus and aluminum atoms as part of its crystalline framework structure.
Abstract: Non-zeolitic molecular sieves are prepared by contacting a body of alumina or silica-alumina (optionally containing reactive sources of phosphorus pentoxide and/or other elements desired in the non-zeolitic molecular sieve) with a liquid reaction mixture containing a reactive source of phosphorus pentoxide (and optionally reactive sources of silica and/or other elements desired in the non-zeolitic molecular sieve), and an organic templating agent, thereby causing the body to react with the liquid reaction mixture and to form crystals of the non-zeolitic molecular sieve within the body.

C. The non-zeolitic molecular sieve is characterized as containing framework tetrahedral components of aluminum and phosphorus and at least one additional framework tetrahedral component, e.g., the non-zeolitic molecular sieve may be a silicoaluminophosphate as described in U.S. Pat. No. 4,440,871.

Abstract: A process for the production of an alkaline earth metal, aluminum-containing spinel/clay composition comprises: (a) combining (1) an acidic, aluminum-containing composition in which the aluminum is present in a positively charged species, and (2) a basic, alkaline earth metal-containing composition to form a gel mixture; (b) mixing the gel with kaolin clay to form a co-gel; and (c) calcining the co-gel mixture to form the alkaline earth metal, aluminum-containing spinel composition in a clay matrix. Alkaline earth metal, aluminum-containing spinel/clays having both high surface areas and very high attrition resistance, and processes for using spinel/clay compositions, e.g., as sulfur oxide and nitrogen oxide removal agent, are also disclosed.

Abstract: Large-pore intercalated clays, for example, smectites, with pillars of aluminum-rare earth element-oxygen oligomers, having unprecedented hydrothermal stability. Product distributions demonstrate desirable synergistic effects (less gas, more gasoline, higher activity) using a mixture of intercalated clay and zeolite.
