title = "Dimethoxymethane production via CO2 hydrogenation in methanol over novel Ru based hierarchical BEA",
abstract = "Dimethoxymethane (DMM), a diesel blend fuel, is being researched with high interest recently due to its unique fuel properties. It is commercially produced via a two step-process of methanol oxidation to make formaldehyde, followed by its condensation with methanol. This study presents a one-pot method of DMM synthesis from methanol mediated carbon dioxide hydrogenation over novel heterogeneous catalysts. The effect of catalyst pore structure was investigated by synthesizing 3 wt% Ru over novel hierarchical zeolite beta (HBEASX) and comparing against Ru doped commercial zeolite beta (CBEA) and desilicated hierarchical zeolite beta (HBZDS). The results showed that 3%Ru/HBEASX provided the best activity for DMM production due to its large average pore size. It also showed the decisive role of SiO2/Al2O3 molar ratio, with SiO2/Al2O3 = 75 providing the highest DMM yield of 13.2 mmol/gcat.LMeOH with ca. 100% selectivity. The activity of 3%Ru/HBEAS3 after 5 recycle steps demonstrated the reusability of this catalyst.",
