Lee, Seung-Hwan Moon, Dong Ju 2024-01-20T16:03:49Z 2024-01-20T16:03:49Z 2021-09-05 2011-10-02 0920-5861 https://pubs.kist.re.kr/handle/201004/129900 The effects of support in Ru-supported catalyst on the conversion of glycerol and selectivity of 1,2-propanediol (1,2-PDO) were investigated in the hydrogenolysis of glycerol. The Ru-based catalysts were prepared by solid phase crystallization and impregnation methods in order to improve 1,2-PDO selectivity. The prepared catalysts were characterized by N(2) physisorption, CO chemisorption, XRD, TPR, NH(3)-TPD and TEM techniques. The catalytic hydrogenation of glycerol was investigated at 453 K, initial H(2) pressure of 2.5 MPa and 20 wt% glycerol aqueous solution for 18 h. It was found that the 5 wt% Ru-CaZnMg/Al catalyst prepared by the solid phase crystallization and impregnation methods showed higher catalytic performance than the other catalysts. The glycerol conversion and 1,2-PDO selectivity obtained were 50% and 85%, respectively. It was found that the selectivity of 1,2-PDO increased with the acidity of catalyst.
