Disclosed is a process for producing alkyl fatty esters from fats/oils and C1 to C5 lower alcohols by a multistage reaction process, which includes feeding fats and oils to a reactor at an upper stage and then sent to a stage at the downstream side while feeding lower alcohols to a reactor at a lower stage, and simultaneously returning lower alcohols recovered from an outlet of the reactor to a stage at the upstream side, thereby repeating the reaction.

Process for producing alkyl fatty esters

Disclosed is a process for producing a fatty alkyl ester and glycerin, including step 1 of reacting fats and oils with C1 to C5 lower alcohols, step 2 of removing the lower alcohols discharged from the outlet of a rector in step 1 until the lower alcohol content is reduced to 8 wt % or less, step 3 of separating the product obtained in step 2 into oil and aqueous phases, step 4 of reacting the oil phase obtained in step 3 with lower alcohols in the presence of an acid catalyst, and step 5 of separating the product discharged from the outlet of a reactor in step 4 into oil and aqueous phases thereby giving fatty acid alkyl esters and glycerin, as well as a process for producing fatty alcohols from hydrogen and the fatty acid alkyl esters obtained in the above process.

Process for producing fatty acid alkyl esters and glycerin

The invention relates to a process for producing a fatty alcohol and glycerin by hydrogenation reaction of fats and oils in the presence of a catalyst, wherein the reaction is carried out in the coexistence of an organic solvent.

Process for producing glycerin and fatty alcohol via hydrogenation

The invention relates to a process for producing an alcohol from fats and oils, including:

Method for producing alcohol

The present invention relates to a process for producing a fatty acid ester by using a fatty acid and an alcohol as starting materials, including reducing the acid value of a raw material supplied to a catalyst layer to an acid value lower than the acid value of a raw material fatty acid and then esterifying the raw material in the presence of a solid catalyst.

Process for producing a fatty acid ester

The present invention relates to a method of producing a fatty acid ester, including reacting fat and oil with an alcohol in the presence of at least one third component, wherein the third component is in a supercritical state or subcritical state under the condition of preventing a uniform phase from forming.

Method of producing a fatty acid ester

The present invention provides a process for producing lower alkyl fatty esters from fatty acids and lower alcohols, wherein lower alkyl fatty esters are produced in higher yield with a reduction in the amount of the remaining fatty acids. The process of the present invention comprises bringing fatty acids into contact with gaseous lower alcohols in fixed bed(s) charged with a weakly acidic solid catalyst by countercurrent operation, by co-current operation and subsequent countercurrent operation or by pseudo-countercurrent operation, thus feeding and reacting the fatty acids and lower alcohols in fixed-bed reactor(s) charged with a weakly acidic solid catalyst to produce lower alkyl fatty esters.

Process for producing lower alkyl fatty esters

The process for preparing an alkylene oxide adduct, including the steps of feeding an organic compound having active hydrogen and an alkylene oxide to a reaction column packed with a solid catalyst, and carrying out addition reaction of the organic compound having active hydrogen with an alkylene oxide in a gas-liquid fixed bed reaction, wherein the alkylene oxide is in a state of gas and the organic compound having active hydrogen is in a state of liquid.
