Kinetics of the hydrogenation of fructose with raney‐nickel

The kinetics of the hydrogenation of fructose have been studied at different conditions. The initial hydrogen consumption rate is independent of the fructose concentration and can be described as a function of the hydrogen pressure. The relations can be understood assuming that hydrogen and fructose are adsorbed on different type of active sites according to a Langmuir‐Hinshelwood model, that a reaction between adsorbed species of atomic hydrogen and fructose is rate controlling, and that the reaction is retarded by adsorption of a product formed during the reaction.
