Chemical synthesis in microreactors is a novel way of synthesis in which the reaction can be carried out in a highly controlled way to obtain better yield and selectivity. In the present work hydrogenation of anthraquinones, which is the first step of commercial hydrogen peroxide production by Reidl-Pfleiderer process, is carried out in a microreactor packed with supported palladium catalyst. The effects of reaction temperature, hydrogen to liquid reactant flow rate ratio, reactor pressure and anthraquinones concentration etc. on conversion and reactor productivity were studied. The data obtained from this microreactor study were compared with the data in conventional reactors reported in literature. The data show, among other advantages of microreactor over the conventional reactor, that the reactor productivity is much higher in the microreactor than the conventional reactors.
