Example 11-3 Adiabatic Liquid-Phase Isomerization of Normal Butane Normal butane, C4H10, is to be isomerized to isobutane in a plug-flow reactor. Isobutane is a valuable product that is used in the manufacture of gasoline additives. For example, isobutane can be further reacted to form iso-octane. The 2014 selling price of n-butane was $1.5/gal, while the trading price of isobutane was $1.75/gal This elementary reversible reaction is to be carried out adiabatically in the liquid phase under high pressure using essentially trace amounts of a liquid catalyst that gives a specific reaction rate of 31.1h1 at 360K. The feed enters at 330K. (a) Calculate the PFR volume necessary to process 100,000gal/day(163kmol/h) at 70% conversion of a mixture 90mol%n-butane and 10mol%i-pentane. which is considered an inert. (b) Plot and analyze X,Xe,T, and rA down the length of the reactor. (c) Calculate the CSTR volume for 40% conversion
