REF system (a), NBK model consisting of perpendicular channels (b)—both with channel number of . In contrast to the REF case, where we allow both types of particles ( and particles) to enter any channel, in the MTC system particles are carried through the channels whereas the particles diffuse along the channels. Black squares indicate catalytic sites where a catalytic transition takes place.
