Abstract: Al2O3 as the carrier, Cu, Co, Ni, Pt/Al2O3 four 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/Al2O3 catalysts 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/Al2O3 catalysts 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.

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。
