Abstract

A new Biodesulfurization method has been considered using Pseudomonas aeruginosa supported on Polyethylene (PE) for Biodesulfurization (BDS) of Dibenzothiophene (DBT) as heavy fuel oil sulphur compound model. The obtained results according to Spectrophotometric analysis at 325 nm showed that 90. 54 % of DBT at the primary concentration about 5 (mg. L ), pH=7, biocatalyst dosage of 0. 1 g, in 37 ° C and after 90 min of contact time has been removed. These optimum conditions have been applied for heavy fuel oil (mazut) samples and the biodegradation of their total sulphur content (TSC) has been investigated by X-ray fluorescence spectrometer (XRF). The obtained results revealed that 33. 075 % of total sulphur content from mazut sample has been removed. Kinetic study predicted the chemisorption process as the rate determining step, as it followed the pseudo-second-order rate equation. The data for DBT adsorption on biocatalyst fitted to the Freundlich isotherm model. Morphology and surface functional groups of the biocatalyst have been investigated by SEM and FTIR, respectively.
