Abstract: Effects of the feed rate, the amount of catalyst and the reaction temperature on the multiphase dehydrogenation reaction of isopropanol in a liquid film reactor with the amorphous alloy Raney nickel as catalyst were studied. The reaction kinetics was researched. The results showed that the effect of temperature was the most significant factor. Compared with the liquid phase dehydrogenation of the stirred tank, this reaction mode effectively improved the hydrogen production rate. The kinetic of Langmuir?Hinshelwood was obtained which agreed well with the experimental results.
