正丁醇的催化部分氧化（CPOX）是生物质制氢的一种替代方法。采用Gibbs自由能最小法对反应进行了热力学分析，结果表明，在700 ℃或更高的温度下，当O-2/丁醇= 1.5 ~ 2.0时，可以获得较高的H-2产率。层状双氢氧化物（LDH）衍生的催化剂被证明是有效的CPOX，和Ni-0.35/Mg2.65Al0.5Fe0.5O4。（5 +/-δ）催化剂在700 ℃下用O-2/丁醇= 2.0的进料产生约4.03摩尔-H-2/摩尔-丁醇。这种更高的活性可以归因于结构和电子性质：存在178.2m2/g的更高表面积，并且获得更多的Ni-0原子并且在31-h CPDX测试中保持稳定。版权所有（C）2013，氢能出版物有限责任公司。由爱思唯尔有限公司出版。保留所有权利。
Catalytic partial oxidation (CPOX) of n-butanol is an alternative route for hydrogen production from bio-mass. An analysis on the thermodynamics using Gibbs free energy minimization method was carried out, and the results indicated that a higher H-2 yield can be obtained near 700 degrees C or above with O-2/butanol = 1.5-2.0. Layered double hydroxide (LDH) derived catalysts were proved effective in CPOX, and the Ni-0.35/Mg2.65Al0.5Fe0.5O4.(5 +/-delta) catalyst produced about 4.03 mol-H-2/mol-butanol at 700 degrees C with a feed of O-2/butanol = 2.0. This higher activity can be attributed to the structural and electronic properties: there is a higher surface area of 178.2 m(2)/g, and more Ni-0 atoms were obtained and remained stable in the 31-h CPDX test.
