Venturi tube and single pipe inlet as gas distributors in hydrogenation of rape seed oil

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 ⪬ c Ni (%) ⪬ 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.
