Research on Adding Hydrogen to Fat of Industry with Low Temperature and Low Pressure

DENG Yu （Department of Chemical Engineering; Tianjin University of Light Industry; Tianjin 300222; China）;

Abstract：In order to raise hydrogenant efficiency, this experiment provided a sort of nickel catalyst at the environment of low temperature and low pressure, simultaneously applied preferably sorptive auxiliary. The characteristic of this hydrogenated technology is low temperature, low pressure, less time and more perfect, the results showed that the optimum technology condition was as follows:reaction time is 100～110min, reaction temperature is 100℃, catalyst dosage is 0.55kg, reaction pressure is 0.55MPa. At this ...

Key words：hydrogenant efficiency; low temperature and low pressure; hydrogenant auxiliary; adding hydrogen to fat with high effect
