The monolith reactor - a novel reactor concept for biological gas purification

摘要

Biological gas treatment has been shown to be an effective and inexpensive technique for the removal of low concentrations of contaminants from waste gas streams. A number of multiphase contacting devices have been developed to improve the contacting efficiency in gas liquid systems. The most widely used technologies are: biofilters, biotrickling filters, and bioscrubbers. This work suggests a novel reactor technology for biological gas treatment; the monolith reactor. The monolith offers some clear advantages over conventional bioreactors such as high mass transfer and a low pressure drop, making it a competitive alternative for conventional biological gas treatment bioreactors. The main potential problem of monoliths is clogging due to biofilm formation. This was experimentally investigated, in a pilot-scale monolith reactor.
