Ecofriendly emulsifier synthesis from esterified waste vegetable oil for wellbore drilling fluids is described. A raw material waste vegetable oil is esterified to produce a methyl ester of the raw material waste vegetable oil. A caustic soda solution is added to the methyl ester resulting in a mixture. The mixture is thermally treated. A pH of the mixture is adjusted resulting in formation of an aqueous phase and a non-aqueous phase. The aqueous phase is separated from the non-aqueous phase.

The present invention relates to novel dicarboxylic diesters as well as the use thereof as for inhibiting the methane production in ruminants.

The present invention discloses a method for co-production and processing of biological energy sources by oil crops, and belongs to the technical fields of oleochemical industry and biomass chemical industry. The method comprises the following steps: husking and drying oil crop seeds to obtain husks of which the moisture content is 5%-12% and oil seeds of which the moisture content is 30%-55%; squeezing and extracting the obtained oil seeds to obtain vegetable oil and oil seed meal; performing esterification reaction on the vegetable oil and alcohol to be separated to obtain bio-diesel and crude glycerol; performing cooking treatment on the husks and/or the oil seed meal in the crude glycerol to be separated to obtain oil crude cellulose and glycerol treating liquid; performing microbial fermentation or anaerobic digestion on the oil crude cellulose and the glycerol treating liquid respectively to obtain biological energy sources or bio-based chemicals. The present invention adopts bio-refining type recycling of industrial oil crops to realize efficient co-production of biological energy sources and obviously increase the utilization rate of biomass raw materials in agriculture and forestry.

Embodiments herein relate to the production of alkyl esters from lipid feed stocks. In an embodiment, a process for producing alkyl esters is included. The process can include mixing a lipid feed stock with an alcohol, water, and at least one of carbon dioxide, carbon monoxide, and/or one or more acids to form a reaction mixture, and contacting the reaction mixture with a catalyst under supercritical conditions for the alcohol, the catalyst comprising a metal oxide. Other embodiments are also included herein.

The present invention pertains to an efficient and large-scale process to produce a medium-chain triglyceride composition with >95% content for C8 (caprylic acid), C10 (capric acid) and C12 (lauric acid), with the content of lauric acid at about 5% or more. The process involves fractionation of fatty acid methyl esters, which are mainly derived from coconut or palm kernel, their esterification to glycerol to synthesize medium-chain triglycerides, and refining them to significantly increase purity and make them fit for human consumption. Such composition can have important uses in food and its preparation, health supplements, cosmetics, and medicine, among others.

Polyols are produced by an alkoxylation process in which a vegetable oil containing hydroxyl functional groups is combined with a DMC catalyst to form a mixture, the DMC catalyst is then activated by adding ethylene oxide and/or propylene oxide to the vegetable oil/catalyst mixture, and ethylene oxide and propylene oxide are added to the mixture containing activated DMC catalyst in amounts such that the total of percentage of ethylene oxide in the polyol plus percentage of primary hydroxyl groups in the polyol produced is from 50 to 77% and the percentage of primary hydroxyl groups is at least 30% but less than 50%. These polyols are useful for the production of molded polyurethane foams, particularly, hot-cure molded polyurethane foams.
