Environmental regulations all over the world are becoming more restrictive concerning the release of atmospheric pollutants associated with the flue gases of combustion systems, particularly the emission of sulphur dioxide SO2. Hence, the need for producers to improve their existing technology and to start considering alternative means of isolating sulphur from fuels has become incumbent. Adsorptive desulphurization of crude oil was investigated using activated manganese dioxide, AM in batch reactor. Results showed that desulphurization efficiency was increased on increasing contact time and sorbent dose. There was 49% reduction of crude oil sulphur content after the process. The respective R2 value of pseudo-first order and pseudo-second order reaction model were 0.8162 and 0.9951 when the experimental data were fitted into them. Thus, pseudo-second-order reaction model better described the desulphurization process with chemisorptions being the rate limiting step. However, there is need to improve on methods and adsorbents that will result in complete removal of sulphur from crude oil. Also, the effects of desulphurization on other physico-chemical properties of crude oil should be examined for future research work.
