A vapor-phase bioreactor has been developed utilizing porous metal membranes in a cylindrical design employing radial flow
as opposed to traditional axial flow for the vapor stream. The system was evaluated for the biodegradation ofp-xylene (p-xylene) from a water-saturated air stream byPseudomonas putida ATCC 23973 immobilized onto sand. The biocatalyst was placed in the annular space between two cylindrical, porous stainless-steel
membranes. Details of the reactor system are presented along with biological data verifying system performance. The feed flow
rate andp-xylene concentration were varied between 60 and 130 cm3/min and 15–150 ppm, respectively. Continuous reactor operation was maintained for 80–200 h with removal efficiencies (based
onp-xylene disappearance) between 80 and 95%. The effluent concentration histories were compared to determine the operating range
of the bioreactor. 相似文献
