US Classification:

422211, 422139, 502353, 502305, 502312, 502439

Abstract:

A catalyst includes a carrier body and a catalytic portion carried by the carrier body. The catalytic portion includes a plurality of distinct layers of catalytic material, which layers may be deposited through atomic layer deposition techniques. The catalyst may have a selectivity for the conversion of alkanes to alkenes of over 50%. The catalyst may be incorporated in a reactor such as a fluidized bed reactor or a single pass reactor.

Thomas E. Snead - Bolingbrook IL, US
Steven A. Cohen - Naperville IL, US
Demond L. Gildon - Romeoville IL, US

International Classification:

C11C 3/00

US Classification:

554163

Abstract:

Methods are provided for refining natural oil feedstocks and producing dibasic esters and/or dibasic acids. The methods comprise reacting a terminal olefin with an internal olefin in the presence of a metathesis catalyst to form a dibasic ester and/or dibasic acid. In certain embodiments, the olefin esters are formed by reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters, separating the olefins from the esters in the metathesized product, and transesterifying the esters in the presence of an alcohol to form a transesterified product having olefin esters.

C11C 3/12

US Classification:

554163, 585254, 585271, 585274, 585273

Abstract:

Methods are provided for refining natural oil feedstocks and partially hydrogenating polyunsaturated olefins and polyunsaturated esters. The methods comprise reacting the feedstock in the presence of a metathesis catalyst under conditions sufficient to form a metathesized product comprising olefins and esters. In certain embodiments, the methods further comprise separating the polyunsaturated olefins from the polyunsaturated esters in the metathesized product. In certain embodiments, the methods further comprise partially hydrogenating the polyunsaturated olefins in the presence of a hydrogenation catalyst, wherein at least a portion of the polyunsaturated olefins are converted to monounsaturated olefins. In other embodiments, the methods further comprise partially hydrogenating the polyunsaturated esters in the presence of a hydrogenation catalyst, wherein at least a portion of the polyunsaturated esters are converted to monounsaturated esters.

International Classification:

C11B 3/02
C11C 3/10

Abstract:

Methods for making specialty chemical products and chemical intermediates using hydroformylation are generally disclosed. Further, compositions and compounds formed using such methods are also disclosed. In some embodiments, methods are disclosed for refining a renewably sourced material, such as a natural oil, to form compositions, which can be further reacted employing the methods disclosed herein to form certain specialty chemical products or chemical intermediates.

International Classification:

C07C 69/67
C07C 69/34
C08K 5/06
C08K 5/11

Abstract:

Dibasic esters (diesters) and their use in plasticizer compositions are generally disclosed. In some embodiments, the diesters are branched-chain esters of long-chain alkanedioic acids, such as octadecanedioic acid. In some embodiments, such plasticizer compositions are used to increase the plasticity of a polymer resin, such as a vinyl chloride resin or poly vinyl butyral. In some other embodiments, such plasticizer compositions are used to lower the glass transition temperature of a polymer resin. In some embodiments, at least a portion of the plasticizer is derived from a renewable source, such as a natural oil.

Assignee:

Elevance Renewable Sciences, Inc. - Woodridge IL

International Classification:

C07C 67/475

Abstract:

Methods of carrying out metathesis reactions of natural oil-derived polyenes (e.g., dienes and trienes), including functionalized polyenes, are generally disclosed herein. In some embodiments, the dienes or trienes contain a terminal carbon-carbon double bond, and the metathesis reaction is selective toward reaction of the terminal carbon-carbon double bonds in the polyene. Compounds made by such methods are also generally disclosed herein.
