The present work is dedicated to the nickel phosphide based catalysts, containing particles, generated in situ in the reaction medium from the different catalytic systems. The present catalytic systems exhibited high activity in the hydroprocessing of furfural. Full conversion of furfural depending on conditions was reached after 0.5−3 hours of reaction at 250−350 °C. 2-methylfuran was obtained as a main product in toluene with the highest selectivity of 77 %. Ethyl levulinate and 2-methylfuran with selectivity of 40 % and 38 % respectively were obtained as main products in ethanol under different conditions. Different reaction medium and nickel phosphide precursors had an influence on the obtained phases of catalysts. Ni12P5 and Ni2P were obtained in toluene from oil-soluble precursors and Ni12P5 was obtained in ethanol from water-soluble precursors.

在不同溶剂中原位生成的磷化镍基催化剂对糠醛进行加氢处理

本工作致力于基于磷化镍的催化剂,该催化剂含有在不同的反应体系中在反应介质中原位产生的颗粒。本催化体系在糠醛的加氢处理中表现出高活性。在250-350°C下反应0.5-3小时后,糠醛根据条件完全转化。获得了2-甲基呋喃作为甲苯的主要产物,其最高选择性为77%。在不同条件下,乙醇中的主要产物分别为乙酰丙酸乙酯和2-甲基呋喃,分别为40%和38%。不同的反应介质和磷化镍前驱物对所获得的催化剂相有影响。
