Abstract: A systems and method for manufacturing a base stock from an ethanol stream are described herein. An example method includes dehydrating an ethanol stream to form an impure ethylene mixture, recovering an ethylene stream from the impure ethylene mixture, and oligomerizing the ethylene stream to form a raw oligomer stream. A heavy olefinic stream is distilled from the raw oligomer stream. The heavy olefinic stream is hydro-processed to form a hydro-processed stream, and the hydro-processed stream is distilled to form the base stock.

Abstract: A process for upgrading an ethane-containing C5− paraffin stream comprises contacting the paraffin stream with an oxygen containing gas in the presence of a selective oxidation catalyst under conditions to selectively oxidize at least part of the ethane in the paraffin stream and produce a first product stream comprising ethylene. At least part of the first product stream may then be contacted with an isoparaffin-containing feed in the presence of a solid alkylation catalyst and under conditions to alkylate at least part of the isoparaffin with at least part of the ethylene and produce a second product stream comprising C6+ alkylate. Alternatively, at least part of the ethylene in the first product stream may be dimerized before the alkylation step.

Abstract: Systems and a method for manufacturing a base stock from a light gas stream are provided. An example method includes oxidizing the light gas stream to form a raw ethylene stream. Water is removed from the raw ethylene stream, and carbon monoxide in the raw ethylene stream is oxidized. Carbon dioxide is separated from the raw ethylene stream, and the raw ethylene stream is oligomerized to form a raw oligomer stream. A light olefinic stream is distilled from the raw oligomer stream and a light alpha olefin is recovered from the light olefinic stream. A heavy olefinic stream is distilled from the raw oligomer stream. The heavy olefinic stream is hydro-processed to form a hydro-processed stream. the hydro-processed stream is distilled to form the base stock.

Abstract: A system and methods for manufacturing a base stock from a light hydrocarbon stream. An exemplary method includes cracking the light hydrocarbon stream to form a raw product stream. Water is removed from the raw product stream to form an oligomerization feed stream. The oligomerization feed stream is oligomerized to form an intermediate stream. A heavy olefinic stream is distilled from the intermediate stream. The heavy olefinic stream is 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.

Abstract: In a process for upgrading an ethane-containing C5- paraffin stream, the paraffin stream is contacted with an oxygen containing gas in the presence of a selective oxidation catalyst under conditions to selectively oxidize at least part of the ethane in the paraffin stream and produce a first product stream comprising ethylene. At least part of the first product stream is then with an oligomerization catalyst under conditions to oligomerize at least part of the ethylene and produce a second product stream comprising gasoline and/or distillate boiling range hydrocarbons. Gasoline and/or distillate boiling range hydrocarbons are then recovered from the second product stream and at least a part of any residual C5- paraffin stream is recycled to the selective oxidation step.
