| Summary: | 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.
