摘要：

The hydrogenation of methyl oleate was conducted on two catalysts based on Ru, Ru-Sn/gamma- Al-2,O-3 respectively Ru-Sn-Ba/gamma-Al2O3. The catalysts were prepared by sequential impregnation. The distribution of the acid strength of the prepared catalysts was determined by thermic desorption of di ethyl amine in the temperature range from 20 to 600 C. Experiments were carried out on a laboratory echipament using a fixed bed catalytic reactor at a temperature of 275 C, pressure of 100 atm with a methyl oleate volume flow rate (VHSV) of 0.15h(-1) and molar ratio hydrogen/methyl oleate of 10/1. The main compounds identified were saturated and unsaturated fatty alcohols and saturated hydrocarbons. Ru-Sn catalyst activity was superior to that of Ru-Sn-Ba, probably due to an optimal distribution of the acid strength of this catalyst.
