Abstract: Systems and methods are provided for forming alkylate from an isoparaffin-containing feed. Olefins for the alkylation reaction can be generated from a portion of the isoparaffin-containing feed. This can be achieved, for example, by using selective oxidation to convert a portion of isoparaffins into alcohol, such as conversion of isobutane to t-butyl alcohol. The alcohol can then be converted to an alkene, such as conversion of t-butyl alcohol to isobutene, in the alkylation reaction environment in the presence of a solid acid catalyst. The solid acid catalyst can then facilitate alkylation of isoparaffin using the in-situ formed alkenes. A catalyst having an MWW framework is an example of a suitable solid acid catalyst.

Abstract: A system and methods for manufacturing a base oil stock from a light hydrocarbon stream are provided. An example method includes cracking a light hydrocarbon stream to form an impure olefinic stream, separating water from the impure olefinic stream, and oligomerizing the impure olefinic stream to form a raw oligomer stream. A light olefinic stream from the raw oligomer stream and linear alpha olefins are recovered from the light olefinic stream. A heavy olefinic stream is distilled from the raw oligomer stream and hydro-processed to form a hydro-processed stream. They hydro-processed stream is distilled to form the base oil stock.

Abstract: Systems and a method for manufacturing a base stock from a hydrocarbon stream are provided. An example method includes cracking the hydrocarbon stream to form a raw product stream, separating an ethylene stream from the raw product stream, and oligomerizing the ethylene stream to form a raw oligomer stream. A Light olefinic stream is distilled from the raw oligomer stream and oligomerized the light olefinic stream with the ethylene stream. A heavy olefinic stream is distilled from the raw oligomer stream. The heavy olefinic stream is to form a hydro-processed and distilled to form the base stock.

Abstract: Methods and a system for manufacturing a base stock from an ethanol stream are provided. An example method includes dehydrating an ethanol stream to form an impure ethylene stream, recovering an ethylene stream from the impure ethylene stream, and oligomerizing the ethylene stream to form a raw oligomer stream. A light olefinic stream is distilled from the raw oligomer stream and blended with the ethylene stream prior to the oligomerization. A heavy olefinic stream is distilled from the raw oligomer stream and hydro-processed to form a hydro-processed stream. The hydro-processed stream is distilled to form the base stock.

Abstract: A process for producing an aluminosilicate molecular sieve comprises crystallizing a reaction mixture comprising water, a source of silica and seeds of a silicoaluminophosphate and/or an aluminophosphate molecular sieve. The resultant aluminosilicate molecular sieve product can advantageously be substantially free of framework phosphorus.
