Study on hydrogenation of dimethyl oxalate to ethylene glycol
摘要
Abstract
Vapor-phase hydrogenolysis of dimethyl oxalate to ethylene glycol was performed over a series of CuO/SiO2 catalysts with different precipitants (Na2CO3, NH3 -H2O,NaOH) and CuO loading in a fixed-bed reactor at different reaction conditions. All catalysts were characterized by N2 physisorption, N2O-chemisorption, X-ray diffraction (XRD), TG and H2 temperature- programmed reduction (H2-TPR) analysis technique. The results of catalytic tests and characterization indicate that the activity of catalysts is related with the Cu° and improved with the increase of the Cu area. High conversion of dimethyl oxalate (98% ) and selectivity to ethylene glycol(87% ) were obtained over the optimal CuO/SiO2 catalyst (precipitated by NaOH and 50% CuO loading) at optimized reaction conditions. The CuO/SiO2 catalyst also exhibits good stability.关键词
