An immobilized cell reactor with simultaneous product separation. I. Reactor design and analysis

Abstract: A four-phase reactor-separator (gas, liquid, solid, and immobilized catalyst) is proposed for fermentations characterized by a volatile product and nonvolatile substrate.In this reactor, the biological catalyst is immobilized onto a solid column packing and contacted by the liquid containing the substrate.A gas phase is also moved through the column to strip the volatile product into the gas phase. The Immobilized Cell Reactor-Separator (ICRS) consists of two basic gas-liquid flow sections: a cocurrent "enrich… Show more

“…The data show that the capacity of P. stipitis for xylose fermentation is clearly inhibited by ethanol. Some strategies have been developed to remove ethanol from the fermentation broth, such as vacuum fermentation (Cen and Tsao, 1993) or condensation of the recycle gas stream (Dale et al, 1985).…”

“…In this case, ethanol was recovered from the carrier gas stream by adsorbing the volatile components onto activated carbon. In another study Dale et al (1985) recovered the ethanol by condensation of the recycle gas stream. When CO 2 stripping was combined with a gas-lift fermentor, it had both functions of stripping and agitation to control the mixing and mass transfer.…”

“…In recent years, several research groups have studied ethanol fermentation with stripping (4)(5)(6). Stripping can be done in an airlift fermentor, where the CO 2 gas provides mixing as well as stripping.…”
