Abstract: A process for selective oxidation of dimethyl-1,1′-biphenyl to form methyl-1,1′-biphenyl mono-carboxylic acid(s), comprising contacting a solution of dimethyl-1,1′-biphenyl in acetic acid solvent in the presence of a Co(II) acetate catalyst and air, and optionally adding a co-solvent, or adding sodium or potassium acetate, and oxidizing the dimethyl-1,1′-biphenyl under time and temperature conditions sufficient to form one or more methyl-1,1′-biphenyl mono-carboxylic acid(s). The mono-carboxylic acids are advantageously isolated and esterified to form biphenyl mono-esters for use as plasticizers.

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: Integrated methods and systems are disclosed for the production of dimethyl ether. The method may include reforming natural gas to syngas in a first reactor; contacting the syngas produced in the first reactor with a catalyst system in a second reactor to produce dimethyl ether and carbon dioxide; and supplying steam as a cofeed to at least one of the first reactor and the second reactor in an amount sufficient to achieve a Mm value of 1.4 to 1.8 or to improve the hydrocarbon or oxygenate selectivity.

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: In a process for isoparaffin-olefin alkylation, a feed comprising at least one olefin and at least one isoparaffin is contacted under alkylation conditions in the presence of a solid acid catalyst comprising a crystalline microporous material of the MWW framework type to produce an alkylated product. The alkylated product comprises a C8− fraction, which is useful as a gasoline blending stock, and a C9+ fraction, which is separated from the alkylated product and at least partially recycled to the alkylation step.
