摘要
Abstract
Mg,Ca,Al,and Ga modified Ni-Cu/β zeolites were prepared by co-impregnation method,and characterized by XRD and NH3-TPD.The catalysts were used in synthesis of liquefied petroleum gas(LPG) from syngas,and effect of β zeolite modification on the reaction was carried out.Ca or Ga addition not only reduces the selectivity to CO2,but also increases selectivity to LPG.Ga and Ca synergistic exhibit the best performance.The selectivity to CO2 decreases from 23.98％ to 10.26％,and the selectivity to LPG increases from 75.86％ to 78.52％ with 0.25％(w)Ca and 0.10％(w) Ga.The stability of the catalyst with 0.25％(w)Ca and 0.10％(w)Ga was evaluated and the catalyst showed good stability and LPG selectivity after 100 h reaction.关键词
