Diaz R., et.al. (2001), methyl tertiary butyl ether (MTBE) is an alternative zeolite

They investigated the production kinetics with catalysis and found the velocity model as r k (P / P2 ) IIM

demonstrated by experimental studies. A fixed bed reactor will be used for the production of MTBE (C5H12O) from isobutylene (C4H8) and methanol (CH3OH) with a capacity of 80 000 tons/year. The conversion is required to be 98% over I. Assuming that the reaction enthalpy is constant in the range of 0-100 oC and using the following data;

a B C)

Construct the stoichiometric table and write the reaction rate in terms of conversion. Draw iso-velocity curves for rI 0.005 and rI 0.01 (mol/g cat.h).

Write down the PPE and EKD that describe the system, and express the change in bed volume and conversion and temperature (dx/dV, dT/dV). Place the fixed bed reactor, which will be operated adiabatically, with a feed temperature of 303 K, on iso-velocity curves. Determine the output current temperature when 60% conversion is reached.
