Question

The irreversible elementary gas-phase reaction A + B ) C + D is carried out isothermally at 305K in a packed bed reactor with 100 kg catalyst of particle size 8 mm. The entering pressure is 20 atm and the exit pressure is 2 atm. The feed rate is equal molar in A and B and the flow is in the turbulent flow regime, with FA0-10 mol/min and CA 0.4 mol/dm3. Currently 80% conversion is achieved. a) What would be the conversion if the catalyst particle size is doubled and everything else b) What would be the conversion if the catalyst particle size is halved and everything else remains c) Qualitatively what will be the effect on conversion if the flow is adjusted to laminar flow regime d) What will be the conversion if the exit pressure is adjusted at 4 atm and everything else remains the same? the same? and everything else remains the same including the original catalyst particle size? remains the same including the original catalyst particle size? State any assumption you make.
