Depending on the Stock Quality, one or several of Hycon MB Reactors such reactors are used before the conventional Catalytic Fixed-Bed Reactor.

The Catalyst and Stock enter the Reactor Top and move in parallel Flow. Catalyst Particles move down under the force of gravity much slower as compared with the linear Stock velocity and leave the Reactor Bottom. Catalyst motion provides for its continuous On-Stream Addition and Removal from the System through the special Hatches at the Reactor Top and Bottom. Catalyst Replacement allows maintaining of the required activity level, and its frequency depends on the Catalyst Deactivation Rate. Metals and Stock Salts removed in the Upper Catalyst Beds are withdrawn together with the Catalyst from the Reactor Bottom.

The pressure can exceed 200 atm, and temperature can be in the range of 400–427°C.
