Question

Coke (solid) at 25°C and carbon dioxide (CO$_2$) at 200°C are fed to a continuous reactor. The reaction that occurs in the reactor is as follows: C (solid) + CO$_2$ (gas) $\rightarrow$ 2CO (gas): $\Delta H^\circ$ = 172.47 kJ/mol The solid coke contains 100 wt% carbon. The feed rate of coke is 14 kmol/s, and the feed rate of carbon dioxide is 20 kmol/s. The percentage conversion of carbon in the reactor is 75%. The gaseous products and the unreacted solid carbon leave the reactor at 900°C. Calculate the heat supplied to the reactor. Carbon (C), 14 kmols/s. 25°C CO$_2$(g), 20 kmols/s, 200°C 75% conversion Reactor Q, kJ/s Product gas mixture, 900°C, ?

          Coke (solid) at 25°C and carbon dioxide (CO$_2$) at 200°C are fed to a continuous reactor.
The reaction that occurs in the reactor is as follows:
C (solid) + CO$_2$ (gas) $\rightarrow$ 2CO (gas):
$\Delta H^\circ$ = 172.47 kJ/mol
The solid coke contains 100 wt% carbon. The feed rate of coke is 14 kmol/s, and the
feed rate of carbon dioxide is 20 kmol/s. The percentage conversion of carbon in the
reactor is 75%. The gaseous products and the unreacted solid carbon leave the reactor
at 900°C.
Calculate the heat supplied to the reactor.
