This　study　carries　out　the　methanol　steam　reforming　to　produce　hydrogen　with　the　simulated　engine　exhaust　heat　over　non-noble　Cu-Zn/Al2O3-ZrO2　catalyst.　An　apparatus　was　designed　to　complete　catalytic　reforming　experiments,　and　multiple　parameters　were　adjusted　to　improve　the　hydrogen　yield　and　find　the　better　reforming　method.　The　results　showed　that　the　reaction　temperature　was　the　key　factor　in　the　methanol　steam　reforming.　The　hydrogen　volume　fraction　in　syngas　increased　with　the　increase　of　temperature.　Meanwhile,　the　gas　hourly　speed　velocity　could　affect　the　residence　time　directly　of　methanol　vapor　on　the　surface　of　the　catalysts.　Therefore,　the　effect　of　reforming　was　better　when　the　gas　hourly　speed　velocity　achieved　to　minimum:　376　h-1.　And　the　optimal　water　methanol　molar　ratio　and　feedstock　flow　rate　were　6:1　and　0.4　mL/min,　respectively.　When　the　reaction　temperature　was　600°C,　the　hydrogen　volume　fraction　in　the　reformed　gas　could　achieve　to　56.61%　at　the　best　conditions.　Thus,　the　steam　reforming　of　methanol　over　Cu-Zn/Al2O3-ZrO2　catalyst　may　become　a　promising　and　practical　way　for　producing　hydrogen　on　vehicles.
