Abstract:
1. A micro-channel reactor for producing synthetic natural gas containing methane gas from synthetic gas, the micro-channel reactor comprising: an upper plate including a reactant introduction pipe and a cooling fluid discharge pipe formed at different positions on an upper surface thereof, the reactant introduction pipe introducing synthetic gas containing hydrogen and carbon monoxide therethrough; a lower plate including a cooling fluid introduction pipe and a product discharge pipe formed at different positions on a lower surface thereof, the product discharge pipe discharging a product containing methane gas produced after reaction; an upper heat exchanger disposed under the upper plate and including a reactant introduction through-hole, a cooling fluid introduction through-hole and a cooling fluid discharge through-hole, which are formed at positions corresponding to the reactant introduction pipe, the cooling fluid introduction pipe and the cooling fluid discharge pipe, respectively, the cooling fluid introduction through-hole being fluid-communicated with the cooling fluid discharge through-hole; a lower heat exchanger disposed on the lower plate and including a product discharge through-hole, a cooling fluid introduction through-hole and a cooling fluid discharge through-hole, which are formed at positions corresponding to the product discharge pipe, the cooling fluid introduction pipe and the cooling fluid discharge pipe, respectively, the cooling fluid introduction through-hole being fluid-communicated with the cooling fluid discharge through-hole; an upper gas distributor disposed under the upper heat exchanger and including a reactant introduction through-hole, a cooling fluid introduction through-hole and a cooling fluid discharge through-hole, which are formed at positions corresponding to the reactant introduction pipe, the cooling fluid introduction pipe and the cooling fluid discharge pipe, respectively, the upper gas distributor including a first porous channel fluid-communicated with the reactant introduction through-hole; a lower gas distributor disposed on the lower heat exchanger and including a product discharge through-hole, a cooling fluid introduction through-hole and a cooling fluid discharge through-hole, which are formed at positions corresponding to the product discharge pipe, the cooling fluid introduction pipe and the cooling fluid discharge pipe, respectively, the lower gas distributor including a second porous channel fluid-communicated with the product discharge through-hole; and a porous nickel plate catalyst part disposed between the upper and lower gas distributors and including a cooling fluid discharge through-hole and a cooling fluid introduction through-hole, which are formed at positions corresponding to the cooling fluid discharge pipe and the cooling fluid introduction pipe, respectively, the porous nickel plate catalyst part including a porous nickel plate being fluid-communicated with the first porous channel and the second porous channel, wherein the upper plate, the upper heat exchanger, the upper gas distributor, the porous nickel plate catalyst part, the lower gas distributor, the lower heat exchanger and the lower plate are stacked in the described order; and wherein the first porous channel or the second porous channel has a three-dimensional (3D) channel, and the 3D channel has a mesh and lattice structure.
