Substance ' A ' is important raw material in the fragrance and perfume industry. Recent work has focused on gasphase catalyzed hydrogenation of ' A ' to ' C '. The reaction on a nickel-silica catalyst was found to be zero-order in ' A ' and first order in hydrogen (B) with a specific reaction rate at 170C of 1.74molA/(kg cat min atm). The reaction mixture enters the packed-bed reactor at a total pressure of 5atm. The molar feed consists of 67%B and 33%A at a total molar flow rate of 40mol/min. A+2B3C a) Neglecting pressure drop, calculate the catalyst weight necessary to achieve 75% conversion. b) Accounting for pressure drop in the packed bed using a value of =0.027kg1, redo part (a). c) One engineer suggests that instead of changing catalyst size it would be better to pack the catalyst in a shorter reactor with twice the pipe diameter. If all other conditions remain the same, is this suggestion better
