The following first-order gas-phase reaction occurs in an isothermal, isobaric PFR reactor: A->2B. There is 60% A and 40% inert in the initial feed. If the volumetric flow rate at the outlet of the reactor is 1.3 times of the one at entrance, calculate the conversion rate of the reactor. Assume ideal gas law (PQ = NRT)
Continuously operated stirred tank reactor has been design on the assumption of perfect mixing to achieve 90% conversion of the first order reaction. Subsequent flow patterns study (flow visualization and RTD measurements) indicate that: (i) 65% of the volume is well mixed, (ii) 20%, of the volume locally exhibits plug flow (ii) 15% volume is inactive and 25% of the feed bypass the reactor.
