The effect of hydrogenation conditions on rate of hydrogenation of rape seed oil was studied in a laboratory stirred tank reactor of 250 ml volume, with nickel on kieselguhr catalyst within the range of conditions (150 ⪬ t(°C) ⪬ 190), (0.1 ⪬ P(MPa) ⪬ 1.0), and (0.01 ⪬ cNi(%) ⪬ 0.37). On the basis of these results a comparison of the effect of a Venturi tube and single pipe gas inlet as gas distributors on hydrogenation rate was made in a bench scale unit of 5 l volume.
