The irreversible hydrogenation of ethylene to produce ethane takes place in a PBR over a Ni/support catalyst at 400 K. Treat this second order reaction as elementary (although in real life it is not). The rate constant at 400K is k = 0.2 L( a) If a stream containing equimolar amounts of ethylene and ethane enters the PBR at 400 K and5 atm, with a total volumetric flow of 8 L/sec, apply the algorithm to determine what mass of catalyst is required for a conversion of 70%? (Ignore pressure drop).
