磷化过程对MoP催化剂醋酸加氢合成乙醇性能的影响
Effects of phosphating process of MoP catalyst on hydrogenation of acetic acid to ethanol
摘要
Abstract
A series of molybdenum phosphide (MoP) catalysts for the hydrogenation of acetic acid to ethanol were successfully synthesized and identified by means of X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS) and Scanning electron microscope (SEM).The results reveal that MoP2O7 and MoO2 exist on the catalyst surface together with MoP.MoP or the synergistic effects of MoP2O7 and MoO2 species play roles in hydrogenation of acetic acid to ethanol.Phosphating temperature significantly affects the formation and dispersion of phosphide.A low phosphating temperature is not sufficient for the formation of MoP, but a high phosphating temperature leads to the agglomeration of MoP.The catalyst reduced at 650℃ has the highest hydrogenation activity and its P/Mo molar ratio is 1.0.关键词
