| 中文摘要 | This invention disclosed a method for producing 1,2-propplene glycol from bio-based glycerol. In this method, a CuO-CeO2-SiO2 catalyst is filled into a fixed bed reactor, a glycerol solution is flowed into the reactor together with hydrogen gas in a manner of top feeding, and controlling the reaction temperature to be 170-200℃, the reaction pressure to be 1.0-5.0 MPa, so as to realize the production of 1,2-propylene glycol from the hydrogenation of glycerol. The catalyst used in this invention can sustain a high selectivity for the target product and a high conversion for glycerol for 500 hours. |
