中文摘要:
      采用溶剂热法合成磷化镍(Ni-P)催化剂,在180 ℃水热釜中,以NiCl2·6H2O为镍源、NaH2PO2·H2O为磷源、乙二醇为溶剂、n(P):n(Ni)=3:1,经12 h高温制备得到,并采用XRD、SEM、H2-TPR、N2吸附脱附对催化剂进行表征。催化剂应用于糠醛加氢制备环戊酮的反应中效果良好,考察结果显示较优的工艺条件为:以水作为溶剂,原料与催化剂质量比为12,在反应温度150 ℃、反应压力2.0 MPa、转速600 r/min的情况下反应4 h,糠醛转化率达到98.87%,环戊酮收率为68.65%。对催化剂进行稳定性测试,5次重复使用之后环戊酮收率下降3.25%,考虑到重复实验中催化剂的损失可以视为催化剂重复性良好。
英文摘要:
      Ni-P catalysts were prepared by the solvothermal method. Ethylene glycol, NiCl2•6H2O and NaH2PO2•H2O were used as the solvent, the nickel source and the phosphorous source respectively, where n(P):n(Ni)=3:1. Catalysts were characterized by XRD, SEM, TEM, H2-TPR, H2-TPD, N2 adsorption-desorption as well as XPS. Then, experiments were carried out to evaluate Ni-P catalysts under different reaction conditions. Ni-P catalysts exhibited outstanding performance during the hydrogenation reaction under optimized conditions, where the conversion of furfural and the yield of cyclopentanone reached 98.87% and 68.65%. Finally, research results indicated that no obvious decrease were observed in catalytic performance after 5-time regeneration cycle. Thus, Ni-P catalysts demonstrated good stability as well.
