The two-phase reactor water/silicon-oil: prospects in the off-gas treatment

A research was carried out to develop a biphasic biological reactor able to cleanse the gas effluents polluted by volatile organic compounds. Initially, Rhodococcus erythropolis T 902.1 had been selected on the basis of its good capacity to degrade a compound selected as model (isopropyl-benzene). The “Doehlert” statistical model was selected to estimate the effect of gas flow and the IPB concentration on the biodegradation of IPB. The two factors chosen in this first step are the gas flow and the concentration in IPB of this one. The results shows that the use of silicon-oil makes it possible to absorb large quantities of IPB within the medium of biological abatement. On the other hand, the rate of biodegradation is directly related to the inlet flow of IPB. Thus, the reactor is able to degrade more than https://www.w3.org/1998/Math/MathML" display="inline"> 7 m g / m i n .
