Micro-channel water-gas shift reaction device having built-in flow-through-type metal catalyst

A micro-channel water-gas shift (WGS) reaction device comprising:

• an upper plate including a heat transfer gas supply pipe which is connected with a heat transfer gas supply source to supply a heat transfer gas, and a product gas discharge pipe for discharging a product gas;
• a lower plate including a reactant gas supply pipe which is connected with a reactant gas supply source to supply a reactant gas, and a heat transfer gas discharge pipe for discharging the heat transfer gas;
• an upper heat transfer unit which is disposed under the upper plate and includes an upper heat transfer gas flow path which is connected with the heat transfer gas supply pipe to flow the heat transfer gas, and an upper product gas flow path which is formed in contact with the upper heat transfer gas flow path so as to allow heat transfer therebetween, and connected with the product gas discharge pipe;
• a lower heat transfer unit which is disposed on the lower plate and includes a lower heat transfer gas flow path which is connected with the heat transfer gas discharge pipe to flow the heat transfer gas, and a lower reactant gas flow path which is formed in contact with the lower heat transfer gas flow path so as to allow heat transfer therebetween, and connected with the product gas supply pipe;
• and
• at least one reaction units laminated between the upper heat transfer unit and the lower heat transfer unit,
• wherein the reaction unit, in order to be laminated in one or more layers, includes:
• a gas supply plate on which a gas supply channel for communicating only with the lower reactant gas flow path is installed;
• a metal catalyst plate which is laminated on the gas supply plate and has at least one metal catalyst mounted thereon and at least one porous metal retainer disposed under the metal catalyst;
• a gas transfer unit which is laminated on the metal catalyst plate to transfer the gas reacted with the metal catalyst to the upper product gas flow path;
• and
• an endothermic plate which is disposed under the gas supply plate or on the upper gas transfer unit and has an endothermic channel for communicating the upper heat transfer gas flow path with the lower heat transfer gas flow path, and
• wherein the gas supply plate, the metal catalyst plate, the gas transfer unit, and the endothermic plate include first reaction through holes communicated with the upper product gas flow path, second reaction through holes communicated with the upper heat transfer gas flow path, third reaction through holes communicated with the lower reactant gas flow path, fourth reaction through holes communicated with the lower heat transfer gas flow path, respectively.
