摘 要: 以切削法加工的铜纤维为原料,退火后按均一方向排列,利用固相烧结技术制成一种具有微通道特征又有高比表面积的定向切削铜纤维烧结板。采用浸渍法将Cu/Zn/Al/Zr四元体系催化剂负载于定向切削铜纤维烧结板上,系统研究纤维板的孔隙率、长度和微反应器的分布腔形状对甲醇水蒸气重整制氢微反应器制氢性能的影响。结果表明:定向切削铜纤维烧结板孔隙率为80%,甲醇转化率和H2流速明显优于其他结构的纤维板,对称腔反应器相对于斜角腔反应器也具有较佳的制氢效果。
关 键 词: 一次能源;催化剂载体;定向切削铜纤维烧结板;制氢;微反应器

Abstract: Continuous copper fibers were cut by a multi-tooth tool, arranged in the same direction after annealed, then made into oriented linear copper fiber sintered felts (FSF) which had microchannel and high specific surface area character by solid phase sintering technology. Cu/Zn/Al/Zr catalyst was coated on the FSF by an impregnation method, and then the coated FSF was used in a methanol steam reformer (MSR) for hydrogen production. Effect of porosity and length of FSF, distribution chamber of MSR on hydrogen production of MSR was studied. Obvious advantages were observed in methanol conversion and H2 production rate when the porosity was 80%. The result was better when symmetry chamber of MSR was used than oblique chamber did.
Key words: primary energy; catalyst support; oriented linear copper fiber sintered felts; hydrogen production; methanol steam reformer
