Desulphurization of Model Oil using Immobilized [BMIM]FeCL. onto Polysulfone (PSF)

Final Dissertation of the experiment "Desulphurization of Model Oil using
Immobilized [BMIM]FeCl4 onto Polysulfone (PSF)" is the requirement of
complementation of Final Year Project 2. Desulphurization has become one the
important criteria that need to be concentrated especially in oil industries. Other than
the conventional Hydrodesulphurization, many methods and alternatives have been
discovered and yet to be discovered on order to cater the advance technology of
Chemical Engineering, as well as the quality of the existing crude oil throughout the
world One of the major methods is desulphurization using ionic liquids. Ionic liquid
is a new technology that can help to improve the quality of desulphurization due to its
nature and jUnction. [BMIM}FeCl4 has been found out that it is the most suitable
ionic liquid to desulphurize model oil. However, a limitation occurs as the ionic liquid
exists in liquid form which later will cause a problem in doing the Liquid-Liquid
Extraction. Thus, a new method is required to overcome this problem, which is the
immobilization technique, Spraying Suspension Dispersion (SSD). SSD can
immobilize any ionic liquid onto a solid structure, such as [BMIM]FeC14 onto
Polysulfone (PSF). It works by dissolving the [BMIM]FeCl4 together with PSF using
dichloromethane and later they are sprayed into water solution. The water will wash
away dichloromethane and as a result, droplets of PSF with [BMIM]FeCl4 onto it are
produced These droplets will solidifY and become a solid compound. The results from
characterization has proven that [BMIM]FeCl4 has been successfitlly hooked onto
PSF. The desulphurization results also have shown that the immobilized
[BMIM]FeCl4 can still remove sulphur from model oil. Thus, this is a new method of
desulphurization that engineers can go into and study into details.
