A method for producing fatty acid - methyl esters or fatty acid - ethyl esters and glycerol by transesterification of oils or fats

摘要

oils and fats, especially vegetable and animal origin, with methanol or ethanol and an alkaline catalyst in liquid phase is implemented. there are glycerol and fatty acid methyl esters or fatty acid ethyl esters -.it works with at least two umsetzungsstufen, each umsetzungsstufe a mischreaktor and a separator for separating a light esterreichen phase and a heavy phase is glycerinreichen. the mischreaktor first umsetzungsstufe leads the oil or fat, the alcohol and the catalyst and mixing these substances are intense.the mischreaktor second and every other umsetzungsstufe leads to intense mixing of the alcohol and the catalyst and the obtained in the preceding umsetzungsstufe light, esterreiche phase. in the second to last umsetzungsstufe separator is a heavy phase is separated and at least partially back to the mischreaktor first umsetzungsstufe led.from in last umsetzungsstufe separated light, esterreichen phase comes from the at least one other separationsbehandlung fatty acid methyl ester or fatty acid ethyl esters. you work with two umsetzungsstufen preferably.
