CATALYST-COATING LIQUID OF THE MIXTURE OF THE NICKEL-BASED CATALYST AND ACRYLIC ACID OR THE ACRYLIC ACID ACETIC ACID ARE USED THE CATALYST-COATING METHOD AT THE MICRO CHANNEL

摘要

PURPOSE: The coating layer can be formed uniformly in comparison with the catalyst layer using only the nickel-based catalyst on the micro channel. In the point of the coating solution, adjustment easies. It has no the phenomenon that the catalyst layer is cracked after the case of reacting methanol-reformate or chafing.;CONSTITUTION: The catalyst-coating method at the micro channel of micro reactor comprises next steps. The step forming oxide layer in the top of the substrate having micro channel. With step of filling the micro channel it spills and it puts the catalyst-coating liquid in the micro channel of substrate. Step forming the catalyst layer in the inner wall of the micro channel by the surface tension of the solvent in which substrate is desiccated and which is included in the catalyst-coating liquid.;COPYRIGHT KIPO 2011
