Prospects of Application of Spent Autocatalysts: Rh Catalysts for Processing of Renewable Citral

Abstract
Data on the activity of model bimetallic catalysts 1%Rh5%Co/ZrO2, 1%Rh5%Cu/ZrO2 and 1%Rh1.5% MnOx/SiO2 in the hydrogenation of renewable citral under mild conditions (70 °C, 10 atm gauge H2) have been obtained. It is shown that the citral hydrogenation rate increases in the series RhCu/ZrO2 < RhMnOx/SiO2 < RhCo/ZrO2, reaching selectivity to citronellal of 70, 78 and 84 %, respectively, at citral conversion of 46 %. It is hypothesized that the presence of impurities of Co, Cu, Mn, silicon oxide and reduced oxides will not affect the hydrogenation activity of Rh in spent autocatalysts.
