Using a nickel-based catalyst placed in tubes, steam reforming of propane (reaction R1) occurs according to the following reaction:

.

Another reaction, the water-gas shift reaction (reaction R2) also takes place in the reactor and produces more hydrogen according to

.

The standard heat of reaction R1 is . Thus, this reaction is endothermic. On the other hand, reaction R2 is mildly exothermic, and its standard heat of reaction is . Thus, heat must be added to the reformer, using burners to heat the tubes. You can set the value of the heat added (in kW) to the reactor , as well as the temperature of the outlet stream. The outlet stream's pressure is equal to 1 atm. Assume that the propane is entirely consumed, so that the extent of reaction R1 is .
