Abstract: Subject-matter of the invention is a process for producing fatty alcohols by catalytic hydrogenation of fatty acid methyl ester (FAME), in which the FAME initially is hydrogenated to fatty alcohol (FA). The fractions of non-converted FAME remaining in the hydrogenation product are converted to wax ester and methanol in a succeeding transesterification step with FA. According to the invention, catalysts on the basis of magnesium oxide or hydrotalcite are used. After separating the methanol and the FA as target product, a stream enriched in wax ester is recirculated to the hydrogenation reactor.

Abstract: A method for the continuous extraction of impurities, in particular saponification products, from a fatty acid alkyl ester phase produced by transesterification of vegetable or animal oils or fats with a great tendency to form saponification products, by means of an aqueous, acid glycerol phase containing a complexing agent.

Abstract: A method for reprocessing a phase substantially consisting of steryl glycoside/fatty acid alkyl ester/water agglomerates, which was formed when fatty acid alkyl ester generated by transesterification of vegetable oils or animal fats was washed with water, wherein the water content is evaporated by heating the phase and subsequently the steryl glycosides are split into their sterol and sugar fractions in the presence of an acid catalyst.

Abstract: A method for the enzymatic breakdown of phosphorus-containing constituents and glycosides, in particular steryl glycoside, from crude oil or pre-degummed oil of vegetable or animal origin, wherein for both cases the addition of the enzymes is effected in one method step.

Abstract: The object of the invention is a process and agents to remove metal contaminants from hydrocarbon fractions like those obtained as a product from the Fischer-Tropsch synthesis involving the use of suspended catalyst. As per the present invention, the feed hydrocarbon fraction is treated with a demetallizing agent, comprising at least one sulfur source and at least one basic compound, under anhydrous conditions. The metals to be removed are obtained in the form of precipitate that can be easily separated by means of a mechanical separation process such as filtration, for example.

Abstract: A method for processing solid, organic wastes obtained in the production of vegetable oil, for example the production of palm oil, chiefly consisting of pressing residues of the oil plants and/or oil seeds and oil-containing waste water by hydrothermal carbonization (HTC), wherein the oil present in the waste water in emulsified form is sorbed by the solids rich in carbon, which are obtained from the solid wastes.

Abstract: In a process for the continuous recovery of free tartaric acid from raw materials containing potassium hydrogentartrate, the same are mixed with water and the potassium hydrogentartrate is dissolved. The process is improved in that the suspension is decanted, the clarified liquid is refiltered, the filtrate is cooled to crystallization temperature under a vacuum, the potassium hydrogentartrate crystals formed are dissolved, the solution is subjected to a cation exchange, and the tartaric acid solution obtained is evaporated.

Abstract: A method for improvement of the long term stability of biodiesel is described, in which the crude ester produced by transesterification of a vegetable or animal fat or oil with methanol, with a strong acid or with a mixture of a strong acid and a complex former is subsequently treated intensively and the ester layer separated from the emulsion formed thereby is subjected to a thorough water washing and subsequently dried.

Abstract: Process for producing tartaric acid from a raw material whose dry matter comprises at least 5 wt% potassium hydrogentartrate wherein the raw material containing potassium hydrogen tartrate (KHT) is mixed with aqueous potassium hydroxide solution in a first reaction stage, where KHT is virtually completely reacted to form dipotassium tartrate (DKT), the aqueous solution containing DKT is then mixed with added acid in a precipitation stage at a pH value of 2.0 to 5.0, to produce a suspension containing crystallized KHT; crystallized KHT is then separated from the suspension, washed with water, and there is produced a solution at least 80 wt-% saturated with KHT and then the potassium is removed, to obtain an aqueous tartaric acid product solution, from which water is then at least partly removed.

Abstract: A process is for the continuous production of beer having a diacetyl content below 0.1 mg/l from a cooked, unfermented, fermentable wort with an oxygen content of 0.5 to 3.0 mg O.sub.2 per liter.

Abstract: A continuous process of producing beer is described. Starch-containing raw materials are disintegrated and are optionally processed to form malt, a wort is produced from the disintegrated and optionally malted raw materials, and the wort is subjected to alcoholic fermentation. In that process all process steps are performed continuously. The mash is initially heated in a reactor system to a temperature of 75.degree. to 85.degree. C. The grain residue is removed from the mash. The wort is subsequently hopped and is heated to a temperature from 105.degree. to 140.degree. C. This is succeeded by a flash evaporation, a removal of the dregs and a cooling of the wort, which is subsequently fermented at 6.degree. to 25.degree. in the presence of a biocatalyst. The fermenting process may be succeeded by a partial or full continuous de-alcoholization of the beer.

Abstract: A process is disclosed for preparing an organic acid and/or its salts from a solution obtained through fermentation. In this process, a pure carbohydrate-containing raw material is used. The acid-containing solution prepared by means of fermentation is supplied to a cell separation, and the acid-containing permeate is supplied to a protein precipitation, where it is mixed with a silicon-containing precipitant at temperatures between 2.degree. and 70.degree. C. The solution thus obtained is supplied to a protein separation, and the acid-containing permeate is concentrated and then supplied to a single- or multi-stage crystallization or a granulation.
