Fix bed reactor
WebOne of the commonest applications of fixed bed pgm catalysts in the non-petrochemical Industries is to produce high purity gases. This uses pelleted catalysts generally comprising ≤ 0.5% by weight of pgm, supported on either ceramic extrudates, compressed tablets or spheres. With such a catalyst, traces of oxygen (O 2) can be removed from ... WebJan 1, 1991 · Abstract. A two-zone grain-pellet model has been used to simulate catalyst regeneration in fixed bed reactors. Changes in coke composition during reaction and non-uniform coke distributions in the reactor have been accounted for, as well as inter- and intraparticle heat and mass transfer resistances. The model calculates the temperature …
