Q5/ n- Butane is converted to isobutene in a continuous isomerization reactor that operates isothermally at (140°C). The feed to the reactor contains (91%) of n-butane, (6%) of isobutene, and (3%) HCL at (140°C) and (45%) conversion of n-butane is achieved. 1- Taking a basis of (100 mol) of feed gas, calculate the moles of each component of the feed and product mixtures and the extent of reaction 3 (mol). 2- Calculate the standard heat of the isomerization reaction ( KJ/mol). Then, taking the feed and product species at (25°C) as reference prepare an inlet- outlet enthalpy table and calculate and fill in the component amounts (mol) and species enthalpies (KJ/mol). 3- Calculate the required rate of heat transfer (KJ) to or from reactor (state which it is). Then determine the required heat transfer rate (KW) for the reactor feed of (375 mol/h). 4- Use your calculated results to determine the heat of isomerization reaction at (140°C) AĤ,(140°C)KJ/mol.

Q5/ n- Butane is converted to isobutene in a continuous isomerization reactor that
operates isothermally at (140°C). The feed to the reactor contains (91%) of n-butane,
(6%) of isobutene, and (3%) HCL at (140°C) and (45%) conversion of n-butane is
achieved.
1- Taking a basis of (100 mol) of feed gas, calculate the moles of each
component of the feed and product mixtures and the extent of reaction 3 (mol).
2- Calculate the standard heat of the isomerization reaction ( KJ/mol). Then,
taking the feed and product species at (25°C) as reference prepare an inlet-
outlet enthalpy table and calculate and fill in the component amounts (mol)
and species enthalpies (KJ/mol).
3- Calculate the required rate of heat transfer (KJ) to or from reactor (state
which it is). Then determine the required heat transfer rate (KW) for the
reactor feed of (375 mol/h).
4- Use your calculated results to determine the heat of isomerization reaction at
(140°C) AĤ,(140°C)KJ/mol.
