Abstract

Desulphurization of crude oil has lately become one of the most important processes in crude oil refining. Increasingly stringent environmental protection regulations mean that motor fuel producers must improve their existing technology and to start considering alternative means of isolating sulphur from crude oil. Adsorption is a process that can be applied for crude oil desulphurization. The idea is to selectively separate less than 1 wt.% of fuel mass by selective adsorption for removing sulphur, and leave the 99 wt.% of non sulphur-containing crude oil mass untouched. A comparative study was made of the desulphurization potentials of two metal oxides-activated manganese dioxide, AM and activated zinc oxide, AZ. Kinetic and equilibrium analysis of the adsorption process was done. The analysis of residual sulphur indicated that significant sulphur depletion occurred with activated manganese dioxide in the five-hour and six-hour reaction times. Kinetic analysis was best described by pseudo-second-order model. Both Langmuir and Freundlich models were well fitted for the balance analysis of the adsorptive desulphurization.
