Such hot spots can cause the onset of undesired reactions or catalyst degradation. Moving-bed catalytic reactors If a solid catalyst degrades in performance, the rate of degradation in a fixed bed might be unacceptable. In this case, a moving-bed reactor can be used. Here, the catalyst is kept in motion by the feed to the reactor and the product.

A trickle-bed reactor is a type of three-phase reactors in which a gas and a liquid phase cocurrently flow downward over a packed bed of catalyst particles. Most commercial trickle-bed reactors operate adiabatically at high temperatures and high pressures and generally involve hydrogenations, oxidations and desulfurizations. Trickle-bed reactors may be operated in several flow regimes.
