A liquid phase reforming of methanol is one of the promising solutions for designing new process of hydrogen production. As compared with the usual steam reforming reaction, the advantages of liquid phase reforming are making more compact and simple reaction equipment and needless of the evaporation energy of methanol aqueous solution. In this study, the liquid phase reforming of methanol with water over various supported metal catalyst in the batch reactor with suspended powder catalyst around boiling point of solution was studied. The main purpose of our study is the development of more simple and compact system for production of pure hydrogen. In our study on the methanol reforming reaction, Transition metal added Pt group catalyst exhibited much higher activity than non-modified Pt catalysts. Highly dispersed Pt species on the monolayer of added transition metal oxide exhibited excellent activity for the reforming reaction. Support effect for the catalytic activity of liquid phase reforming of methanol with water was investigated over various supported Pt-Ru bimetallic catalysts. The SiO2, TiO2, Al2O3, MgO, CeO2 and ZrO2 were used as support materials by conventional impregnation method. Basic oxide supports improved the selectivity to CO2, whereas acidic supports suppressed the catalytic activity and selectivity.

甲醇液相重整制氢是一种很有前途的制氢新工艺。与通常的水蒸气重整反应相比，液相重整反应的优点是反应设备紧凑、简单，且不需要甲醇水溶液的蒸发能量。在间歇式反应器中，采用悬浮粉末催化剂，研究了不同负载型金属催化剂上甲醇与水的液相重整反应。本研究的主要目的是开发更简单、紧凑的纯氢生产系统。在甲醇重整反应的研究中，添加过渡金属的铂族催化剂比未改性的铂催化剂表现出更高的活性。在添加过渡金属氧化物的单层膜上的高度分散的Pt物种表现出优异的重整反应活性。考察了负载型Pt-Ru催化剂对甲醇水液相重整反应活性的影响。以SiO_2、TiO_2、Al_2O_3、MgO、CeO_2和ZrO_2为载体材料，采用常规浸渍法进行浸渍。碱性氧化物载体提高了CO2的选择性，而酸性载体抑制了催化剂的活性和选择性。
