Abstract
The mass transfer performance of a string film reactor (SFR)-a bioreactor design for the aerobic bioconversion of methane-was investigated. The results showed that the SFR could achieve high mass transfer performance of gases, and the highest values of the mass transfer coefficients for oxygen and methane were 877.1 h(-1) and 408.0 h(-1), respectively. There were similar mass transfer coefficients for oxygen and methane in absorption experiments using air, methane, and air-methane mixed gas under the same liquid flow rate conditions, implying that each gas is delivered into the liquid without mutual interaction. The mass transfer performance of the SFR was significantly influenced by the liquid flow rate and the hydrophilicity of the string material, whereas the magnitude of the gas flow rate effect on the mass transfer performance depended on both the tested liquid flow rate and the gas flow rate. Furthermore, the mass transfer performance of the SFR was compared with those of other types of bioreactors.
