Reactors with moving solid phase Moving-bed reactor: There are various installations of
moving-bed reactors. In the combustion of large coal, the solid phase is in cross-flow to the
air supply by means of a moving strip. In another type of moving-bed reactor, the solid par-
ticles are fed at the top and continuously moe doard to be discharged at the bottom. wnw v
Catalytic reforming and coal combustion are typical applications of this type of reactor.
