ABSTRACT
Hydrocracking has great importance in present day refining due to strict environmental and norms ofquality of fuel. In recent years the demand for middle distillate and gasoline has increased tremendously whilethat of heavy gas has decreased. In the present work we have modeled and then applied five lump schemeto hydrocracker reactor. The first order kinetics was assumed for the conversion in the model developedand Pseudo components were used to simulate the model. The system is modeled as an isothermal tubularreactor with an axial dispersion, where the hydrogen flows upward concurrently with the oil while the solidcatalyst particles stay inside the reactor in an expanded bed regime. MATLAB 7 was used to solve the modelfor a five lump scheme for different values of liquid superficial velocity, reactor length and temperature
