Abstract
An apparatus for reactions between different gases, includes a hollow body having a first feeding section that receives a first gas and is made of a porous material having through-pores, and a second feeding section that receives a second gas and surrounds the first feeding section. The first gas diffuses toward the second feeding section from the through-pores to give rise to a contact reaction between the first gas and the second gas through the through-pores. The end openings of the through pores have an sufficient total area to match the amount of the second reactive gas received, and each end opening has a sufficient area to provide a linear velocity of diffusion of the first reactive gas that is larger than the linear velocity of diffusion of the second reactive gas at the through-pore end openings in the direction opposing the diffusion direction of the first gas.
