摘要:
A method for production of renewable hydrocarbons, including alpha olefins, renewable diesel, synthetic gasoline, and acyl-glycerides, from renewable oils is described herein. Also included is a method for production comprising (a) blending a specific renewable oil mixture with the proper free fatty acid character; (b) acid hydrolysis of the free fatty acids and subsequent purification of the unsaturated and saturated chains; (c) converting the saturated portion into renewable diesel; and (d) reacting the unsaturated free fatty acids via ethenolysis to form alpha olefins, then converting the remaining free fatty acids into either synthetic gasoline or into an acyl-glycerol via glycerolysis.

Processes for producing a linear internal olefin product include the steps of contacting an olefin feed containing C10-C20 vinylidenes and a C10-C20 normal alpha olefin and/or C10-C20 linear internal olefins, a first acid catalyst, and a C1 to C18 carboxylic acid to form a first reaction product containing linear internal olefins, trisubstituted olefins, and secondary esters, then removing all or a portion of the secondary esters from the first reaction product, followed by contacting the secondary esters and a second acid catalyst to form a second reaction product comprising linear internal olefins, and then removing all or a portion of the linear internal olefins from the second reaction product to form the linear internal olefin product. Linear alkanes subsequently can be produced by hydrogenating the linear internal olefin product to form a linear alkane product.
摘要:
The present invention addresses to a process for producing olefins and esters in the C10 to C13 range from fatty acid esters through a catalytic hydrogenation reaction followed by cross-metathesis of the hydrogenated product with light olefins.
摘要:
A self-metathesis process for the production of unsaturated dicarboxylic fatty diacids and/or unsaturated dicarboxylic fatty diesters, wherein unsaturated carboxylic fatty acids and/or esters of unsaturated carboxylic fatty acids are reacted in the presence of at least one defined ruthenium based catalyst compound. A catalyst enhancer compound selected from a sacrificial catalyst or a non-catalyst enhancer may also be used. The process exhibits improved reaction times and/or the catalyst can be used at very low concentrations.

Metal catalyst compounds are disclosed. The catalyst compound are represented by the formula (I-II and VII): wherein M is a Group 8 metal; X is an anionic ligand; L is a neutral two electron donor ligand; K 2 (A-E) is a ditopic or multitopic ligand. Also disclosed is an easy applicable catalyst synthesis and the application in different olefin metathesis processes, e.g. Reaction Injection Molding (RIM), rotational molding, vacuum infusion, vacuum forming, process for conversion of fatty acids and fatty acid esters or mixtures thereof, in -olefins, dicarboxylic acids or dicarboxylic esters, etc.

Embodiments of methods for co-production of linear alkylbenzene and oleochemicals from a natural oil are provided. An exemplary method includes fat splitting the natural oil to form a stream comprising free fatty chains. The method includes fractionating the stream of free fatty chains to separate a first portion of free fatty chains and a second portion of free fatty chains. Further, the method includes processing the first portion of free fatty chains to provide the alkylbenzene product and processing the second portion of free fatty chains to form the oleochemical products.
摘要:
A linear alkyl benzene product and production of linear alkylbenzene from a natural oil are provided. A method comprises the step of deoxygenating the natural oils to form a stream comprising paraffins. The paraffins are dehydrogenated to provide mono-olefins. Then, benzene is alkylated with the mono-olefins under alkylation conditions to provide an alkylation effluent comprising alkylbenzenes and benzene. Thereafter, the alkylbenzenes are isolated to provide the alkylbenzene product.
