摘要
Macroporous ordered alumina was synthesized in a micro-channel reactor, using polystyrene colloidal spherical nano-beads as a template for the formation of the macro pores. A 0.1 M aluminum nitrate solution, used as the precursor for the synthesis of alumina, was mixed with a polysOirene colloidal solution at a volumetric ratio of 1:1. In this study, SUS-316, stainless steel material was used as a micro-channel plate and the buffer layer was homogeneously coated over the micro-channel plate. Scanning electron microscopy confirmed the synthesis of high quality ordered macro porous alumina over the micro channels through the application of a buffer layer To use the ordered macro porous alumina as a catalytic support, the precursor of the active components, Ni, was added to a mixed solution of the aluminum precursor and polystyrene colloid. A channel type heat exchange reactor was used as a fuel reformer for SOFC in this study. The macro-porous Ni-Al2O3 based catalyst coated over the micro-channel plate was inserted into the outside channel. It could be confirmed through this study that the efficiency of heat exchange was enhanced through the use of the micro-channel plate, and the metal foam and the catalytic activity of nickel based catalyst for reforming of dodecane was improved through the use of the macro-porous alumina support.
