Evaluation of power density on the bioethanol production using mesoscale oscillatory baffled reactor and stirred tank reactor

A recent development in oscillatory baffled reactor technology is down-scaling the reactor, so that it can be used for production of small-scale bioproduct. In the present study, a mesoscale oscillatory baffled reactor (MOBR) with central baffle system was developed. The reactor performance of the M...
