摘要:以Al2O3为载体,采用浸渍法制备了Cu、Co、Ni、PtAl2O2四种单一组分催化剂(MA1O3)。研究了
MAl2O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MA2O2催化剂用于
丙三醇水蒸气重整制氯均表现出一定活性;其中CuAl2O催化剂具有一定的抗积炭性;PtA14O3催化剂表现出较
好的抗积炭性、高温活性,但稳定性较差;Co/AlO催化剂表现出较好的稳定性;NiAI2O3催化剂表现出较好的
低温活性

Abstract: A12 O as the carrier, Cu, Co, Ni, Pt/Al O3 four kinds of single component catalysts(M/A1>O3)
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/A120 catalysts have been studied
The preparation conditions and reduction conditions of M/A12O3 catalysts were investigated, and
catalysts were assessed through activity, stability and the resistance to carbon deposition, Catalysts
were characterized by TPR and RD. Studies have found that M/A1 O; catalysts showed some activity
for the steam reforming of glycerin; wherein the Cu/A120; catalyst has certain resistance to carbon
deposition; Pt/Al203 catalyst showed better resistance to carbon deposition, high temperature activity
but poor stability; Co/A12O3 catalyst exhibited good stability; Ni/A12O3 catalyst exhibited good activity
at low temperature
Key words: hydrogen; glycerin; catalyst; M/A12O3
