In the high pressure hydrogenation of high acid valued rice bran oil, authors appointed the optimum composition of unreduced Cu-Ni catalyst in industrial use. But the catalyst could not be useful in low pressure hydrogenation unless roasting.
When there is 1.0% residue of extracting solvent trichloroethylene in oil, its catalytic poisonous action is less than that of formerly believed, but it has a good influence for bleaching and for the hydrogenating velocity regulation, in the high pressure hydrogenation.
In the high pressure hydrogenation, up to 2.0% water content is not bad for results, but it is gradualy influenced from 2.0 to 8.0%, and the hydrolysis of fat is seen according with water content.
The soapstock could not be hydrogenated by 1.0% nickel oxide catalyst. While, if recovered and then refined, it can be hydrogenated by unreduced Cu-Ni even 1.0% catalyst.
