Biodesulfurization
Biodesulfurization (BDS) is that the process of sulphur removal from fuels by means of living organisms. It’s a non-invasive approach which will specifically remove sulfur from refractory hydrocarbons under mild conditions and it are often potentially utilized in industrial desulfurization. The removal of sulphur or sulphur compounds (as from coal or flue gas) using biological agents is named as bio desulfurization. One vertical rotating immobilized cell reactor (VRICR) with the bacterium R. erythropolis, as a biocatalyst, was developed and used for investigation of
biodesulfurization process with its two successive stages of
cell growth and desulfurization activity. With a rotation speed of 15 rpm and oxygen transfer rate of 90 mM O2.l-1.h-1, immobilized cell concentration of up to 70.0 g.l-1 was achieved during the primary stage and further used, within the second, to hold out a stable continuous desulfurization of
model oil (dibenzothiophene in hexadecane). a gentle state with specific desulfurization rate as high as 167 mM 2HBP.Kg-1.h-1 and sulfur removal efficiency of 100% were maintained for quite 120 h. The proposed integrated
biodesulfurization process utilizing the VRICR has the potential to lower operating costs and support possibilities of economic application at the expense of Hydrodesulphurization process currently employed. Sulphur emission through
fuel combustion may be a major explanation for acid precipitation and
pollution . so as to compete successfully with Hydrodesulphurization, bio desulfurization process with an appropriate biocatalytic design has been developed.
