Crude naphtha consists of variable hydrocarbons and undesirable compound such as sulphur which must be removed to prevent corrosion and environmental problems. Existence of sulphur compound also results in deactivating the catalysts, disrupting the catalysts performance, lowering the conversion and selectivity and increasing the temperature that need to be applied for a particular amount of conversion. Therefore this research is doneto developa modelling for a trickle bed reactorofthe processof removal the organic sulphurfrom a crude naphtha. Deep desulfurization is necessary because sulphur content in crude oil is getting higher and higher while the regulated sulphur limits are becoming lower and lower. The essentials of the chemistry and catalysis are well established. There is a great need for reactor development to improveefficiencyand economics. Modelling can be great help in this direction. A dynamic plug flow heterogeneous one dimensional (ID) model was developed to simulate the temperature, concentration profile change alongthe reactorand change a few parameters suchas LHSV and H2/CH ratio to observe the effecton decreasing the sulphurcontent. The modellingis based on the mass and enthalpybalance ofthe reactions. IV
