摘要： The present invention relates to a process for refining glyceride oil comprising a neutralization treatment in which alkali is mixed into crude or water degummed glyceride oil and a separation treatment in which the soapstock formed is separated from the glyceride oil by subjecting the oil to two centrifugal separators in series, in which at least 1 wt. % of the oil passes through both separators twice.

摘要： The present invention relates to a process for the regeneration of spent bleaching earth, comprising an oxidative heat treatment in which the amount of oxygen supplied exceeds the stoichiometrical requirement of complete oxidation of all organics present in the spent bleaching earth, wherein the spent bleaching earth and the oxygen are blown through a stationary fluidized bed of inert granulate material. The stationary fluidized bed should be as high as to limit the temperature in the freeboard to less than 1000.degree. C. As a matter of fact, it has been found that, if the fluidized bed is not high enough, the oxygen required to burn off the organics content of the spent bleaching earth would blow out the powdered bleaching earth from the bed at the stage of incomplete oxidation of the organics present on the earth, resulting in an uncontrolled temperature rise in the freeboard and local overheating of the bleaching earth.

摘要： A novel process for the selective elimination of fatty acid compounds containing carbon-carbon double bonds in trans configuration from a substrate containing cis- and trans-isomers of said fatty acid compounds, by selective adsorption by a microporous zeolite material is disclosed. The pore size and shape of usable zeolite materials enable differentiation between cis- and trans-isomers of unsaturated fatty acid chains. The zeolite materials used have a selectivity ratio &agr;trans/cis higher than 1.00; this ratio is defined based on the elution properties of cis and trans double bond containing fatty acid methylesters dissolved in n-hexane during a column chromatography experiment with the zeolite material as the stationary phase and n-hexane as the mobile phase. Besides selective adsorption of trans-unsaturated fatty acid compounds, simultaneous or subsequent total or partial hydrogenation of the double bonds in said compounds can be carried out while using the same or similar zeolite material, containing finely dispersed catalytic active metals. The majority of these catalytic active sites must be inside the pores.

摘要翻译： 公开了通过微孔沸石材料的选择性吸附来选择性地从含有所述脂肪酸化合物的顺式和反式异构体的底物反式构型中除去含有碳 - 碳双键的脂肪酸化合物的新方法。 可用的沸石材料的孔径和形状使得不饱和脂肪酸链的顺式和反式异构体之间能够分化。 使用的沸石材料具有高于1.00的选择比alphatrans / cis; 该比例基于在沸石材料作为固定相和正己烷作为流动相的柱色谱实验中溶解在正己烷中的顺式和反式双键的溶出性质来定义。 除了反式不饱和脂肪酸化合物的选择性吸附外，所有化合物中双键的同时或随后的全部或部分氢化可以在使用含有精细分散的催化活性金属的相同或相似的沸石材料的同时进行。 这些催化活性位点中的大部分必须在孔内。
