CFD Analysis for Evaluation of Concentration Profile Across of A Fixed Bed Hydrocracking Reactor Abdolali Tousi am toosi@ce iut ac ir Date of Submission 2010 05 22 Chemical Engineering Department Isfahan University of Technology Isfahan 84156 83111 Iran Degree M Sc Language Farsi Supervisor Arjomand Mehrabani arjomand@cc iut ac ir Mohammad Mehdi Akbarnejad m akbarnejad@ripi ir Abstract This thesis presents simulation results of a pilot scale cracking reactor The reactor converts a mixture of aromatic and non aromatic compounds to middle distillate products diesel and kerosine By progressing of reactions undesired products of naphtha and gas are produced Velocity distribution of the feed pressure and temperature have a great impact on concentrations of diesel and kerosine as desirable products Modeling and simulation of flow field in combination with kinetic model can provides more detailed information on the system in comparison with a simple kinetic model Computational Fluid Dynamics simulation method as a new method for estimation of the components concentration distribution in hydrocarbon hydrocracking reactor studied Application software of Gambit 2 3 and CFX 11 are used and model of the packed bed reactor in order to have information on flow lines and velocity vectors and the distribution of concentration for various liquid space velocities and different operating temperatures along the reactor Dimensions operating conditions and the reaction s kinetic model were based on a pilot scale reactor in RIPI Tehran Simulation were done in various space velocities of 0 5 1 0 1 5 and 2 0 cubic meter per hour per cubic meter of catalyst and temperatures of 380 400 420 and 440 C The results show that by increasing the space velocity from 0 5 to 2 0 cubic meter per hour per cubic meter of catalyst at operating temperature of 380 C efficiencies of diesel and kerosine production are decreased from 32 5 to 26 3 percent and from 8 1 to 2 3 percent and in the operating
