摘　　要：以Al2O3为载体,采用浸渍法制备了Cu、Co、Ni、Pt/Al2O3四种单一组分催化剂(M/Al2O3)。研究了M/Al2O3催化剂对丙三醇水蒸气重整制氢反应的适用性及反应行为;考察了制备条件及还原条件,通过活性、稳定性及抗积炭性进行了催化剂的活性评价,并对催化剂进行了TPR、XRD表征。研究发现M/Al2O3催化剂用于丙三醇水蒸气重整制氢均表现出一定活性;其中Cu/Al2O3催化剂具有一定的抗积炭性;Pt/Al2O3催化剂表现出较好的抗积炭性、高温活性,但稳定性较差;Co/Al2O3催化剂表现出较好的稳定性;Ni/Al2O3催化剂表现出较好的低温活性。Al2O3as the carrier,Cu,Co,Ni,Pt/Al2O3four kinds of single component catalysts（M/Al2O3） were prepared by impregnation method.The catalyst applicability and reaction behavior of hydrogen production via the steam reforming of glycerin with respect to the M/Al2O3catalysts have been studied.The preparation conditions and reduction conditions of M/Al2O3 catalysts were investigated,and catalysts were assessed through activity,stability and the resistance to carbon deposition.Catalysts were characterized by TPR and XRD.Studies have found that M/Al2O3catalysts showed some activity for the steam reforming of glycerin;wherein the Cu/Al2O3 catalyst has certain resistance to carbon deposition;Pt/Al2O3 catalyst showed better resistance to carbon deposition,high temperature activity,but poor stability;Co/Al2O3 catalyst exhibited good stability;Ni/Al2O3 catalyst exhibited good activity at low temperature.
