The catalytic cracking of a gas oil charge. A, to form C,+ (B) and to form coke and dry gas (C) is to be carried out in a screw-type conveyor moving-bed reactor at 900F: kB Cs Gas oil kc Dry gas, Coke The reaction can also be written as A Products The reaction follows 2nd order rate law with the following specific reaction rate: -r=0.6- dm g cat.mol.min C The catalytic deactivation is independent of gas-phase concentration and follows a 1st-order decay rate law, with a decay constant of 0.72 min. The reactor contains 22kg of catalyst that moves through the reactor rate of 10 kg/min. the gas is fed at a rate of 30 mol/min at a concentration of 0.075 mol/dm. Given the decay rate law; a = e-(ka/U)w Determine the conversion that can be achieved in this reactor.
