Light gasoline was produced from kerosene at industrial vapor phase hydrocracking plants. The system analysis of the plants was made from the engineering point of view.
The reactor was approximated by a multitubular reactor with internal three-way counter flow heat exchanger and an analytical model for temperature distribution in the reactor was proposed. The calculated values were in good agreement with the experimental results.
Considering the characteristic of this reaction system, there seems to be following several reasons to get this good agreement: (1) rather small heat of reaction, (2) the slow reaction rate, (3) moderate longitudinal temperature distribution in the reactor and (4) using the reasonable physical properties.
