【摘要】 实现CH4和CO的多参数检测,催化剂及其催化反应性能是基础。研究了纳米载体Al2O3的制备方法,对其孔径分布和前驱体的颗粒度进行了BET和TEM的测定,对CH4和CO在Pd/Al2O3催化剂上的催化反应性能进行了评价。结果表明,采用共沉淀-凝胶工艺和控制制备条件可以得到适宜孔径的催化剂载体。CH4和CO在Pd/Al2O3催化剂上的催化反应性能有较大的差异。催化反应可以满足对CH4和CO的多参数检测的需要。更多还原

【Abstract】 Catalyst and its catalytic properties are the basis of multiple parameters determination of CH₄ and CO content.Preparation of nanoparticle alumina carrier was studied,including pore size distribution of the carrier and particle size of its precursor.Catalytic reaction of CH₄ and CO over（Pd/Al₂O₃） were investigated.The results showed that catalytic carrier with moderate pore size could be obtained by co-precipitation-sol-gel method under controlled preparation condition.The reactivity of CH₄ and CO over Pd/Al₂O₃ differed greatly.The Pd/Al₂O₃ catalyst could meet the requirement of multiple parameter determination of CH₄ and CO content.更多还原
