| Abstract: | A novel Pd/Al2O3/cordierite monolithic catalyst was prepared and investigated in hydrogenation of 2-ethylanthraquinone (eAQ) for H2O2 production. It was found that there was an optimal penetrating depth on the monolithic catalyst. By adjusting the loading on the Al2O3, the penetrating depth of Pd could be efficiently confined in the Al2O3 washcoat. When Pd distribution matched well with Pd content, the higher yields of H2O2 could be obtained. As a result, the average yield on monolithic catalyst was 1.3 times of that on pellet catalyst, and the products distribution confirmed the monolithic catalyst was the optimal for H2O2 production. |
