The dynamic modeling of an adiabatic hydrocracking reactor was carried out by using the continuous lumping approach. Vacuum gas oil with 30.6 degrees API and normal boiling temperature range from similar to 285 degrees C to about 329 degrees C was used as feedstock Kinetic model parameters were derived from experimental information at three different reactor temperatures: 360, 370, and 380 degrees C; 1-3 h(-1) LSHV; 356 m(3)/m(3) hydrogen-to-oil ratio, and reactor pressure of 53 MPa. Thermal correlations were chosen to be reliable and dependent on reactivity index. The simulations allowed predicting the dynamic behavior of the reactor regarding temperature and cumulative weight fraction profiles. At the reaction conditions of simulations an increase of almost 10 degrees C was observed in the bed regarding inlet temperature while the reactor position of such maximum was moved to outlet reactor as time on-stream increased.
