A low sulfur diesel blockage inhibitor as shown in formula (I), a preparation method therefor, and use thereof are provided. In formula (I), x and y are each an integer between 0 and 4; m and n are each selected from H, a C1-C6 linear or branched alkyl group, or a C3-C6 cycloalkyl group. By using a vegetable oil as a raw material, a modified vegetable oil fatty acid is first obtained, and then a polar group of an unsaturated dialdehyde with a certain chain length is introduced into a molecular chain of the modified vegetable oil fatty acid.

Disclosed is a process of production of a composition comprising triglycerides, wherein the process comprises a step of esterification and to a fat composition produced by the process. The invention further relates to a structuring fat comprising the fat composition obtained by the process disclosed herein.

The invention relates to methods for the synthesis of hydroxy fatty acids from unsaturated fatty acids via epoxidation and catalytic hydrogenation.

Processes for the production of hydrocarbons from a renewable feedstock in which the renewable feedstock is partially hydrogenated prior to being deoxygenated. The partially hydrogenation utilizes a lower pressure, lower purity or both hydrogen gas compared to the deoxygenation. The partially hydrogenated product may be stored in containers and transported to be deoxygenated. Prior to partially hydrogenation, the feedstock may be pretreated. After deoxygenation an isomerization zone may be used to increase the cold flow properties for a diesel fuel.

Provided herein are processes of preparing sulfonated estolide compounds, and the removal of sulfonate residues from those compounds to provide desulfonated estolide base oils. Exemplary sulfonated estolide compounds include those selected from the formula: ##STR00001##
wherein z is an integer selected from 0 to 15; q is an integer selected from 0 to 15; x is, independently for each occurrence, an integer selected from 0 to 20; y is, independently for each occurrence, an integer selected 0 to 20; n is equal to or greater than 0; R.sub.6 is selected from —OH, optionally substituted alkyl, and optionally substituted aryl; and R.sub.2 is selected from hydrogen and optionally substituted alkyl that is saturated or unsaturated, and branched or unbranched, wherein each fatty acid chain residue of said compounds is independently optionally substituted.

A method is disclosed of purifying a recycled or renewable organic material, wherein the recycled or renewable organic material includes more than 1 ppm silicon as silicon compounds and/or more than 10 ppm phosphorous as phosphorous compounds. The method can include providing a feed of the lipid material; heat treating the organic material in presence of an adsorbent and the filtering organic material and hydrotreating the lipid material in a presence of a hydrotreating catalyst to obtain purified hydrotreated organic material having less than 20% organic material and/or less than 30% of the original phosphorous content of the organic material.

A process for producing a composition having a ratio by weight of C.sub.10-C.sub.26 monobranched fatty acids or alkyl esters thereof to C.sub.10-C.sub.26 polybranched fatty acids or alkyl esters thereof of greater than 6 using a zeolite, preferably ferrierite, isomerization catalyst. The zeolite catalyst is preferably the only isomerization catalyst used. The zeolite catalyst can be reused many times after simple separation from the reaction products without having to be regenerated.
