![]() ![]() With multiple characterizations, the researchers found that the Ca loading enabled the Ca-Fe catalyst to have high surface iron carbides with a proper Fe 2C/(Fe 5C 2+Fe 3C) ratio. “The total oxygenates and alcohols selectivity outperformed the results of previously reported catalysts.” “The proposed synergistic Ca-Fe series catalysts could realize a oxygenate selectivity of 69.7 wt% under mild conditions, alongside the alcohols fraction of 86.4 % in oxygenates,” said Prof. This study was published in Chem Catalysis on March 24. GE Qingjie from the Dalian Institute of Chemical Physics (DICP) of the Chinese Academy of Sciences (CAS) has realized the direct synthesis of higher alcohols from syngas and achieved the highly selective production of higher alcohols from CO hydrogenation over synergistic iron carbides catalysts. However, the low yield of higher alcohols restricted industrial application. With the gradual depletion of petroleum resources, the direct synthesis of higher alcohols from syngas has become a sustainable and potential process because of its wide source of raw materials and high atomic utilization. ![]() They are also widely applied in various fields of fuel, food, fine chemicals, pharmaceuticals and energy. Higher alcohols (C 2+ alcohols), which are important raw materials, have been used as the intermediates of valued products. ![]()
