Abstract: To study the feasibility of using conventional CuZnAl-oxides as catalysts for on-board hydrogen production by autothermal reforming of methanol (ATRM),CuZnAl-oxides catalyst with different copper-zinc ratios are prepared via reverse co-precipitation method.The samples are compared with commercial CuZnAl catalyst SCST-401.It is found that the performance of such type of catalysts improves with the increased mole ratio of copper to zinc.The prepared Cu30Zn10Al catalyst shows the best performance for ATRM in the range of 200-600℃,while Zn40Al catalyst is found to have the similar activity with those of Cu20Zn20Al and Cu10Zn30Al at the temperature from 500℃ to 600℃.In addition,Cu30Zn10Al catalyst can bring about similar methanol conversion with that brought by commercial catalyst SCST-401 that has a much higher copper content than Cu30Zn10Al.Cu30Zn10Al exhibits more stable than SCST-401.Furthermore,Cu30Zn10Al shows higher activity for ATRM at low temperature from 200℃ to 300℃.
