Continuous Stirred-Tank Reactor: Comprehensive …

WebContinuous stirred tank reactors (CSTRs) are frequently investigated in continuous hydrogen production [67–69 ]. In comparison with batch reactors, microbial cultures in a CSTR are evenly suspended in the liquor with lower resistance in mass transfer. Attributable to its intrinsic reactor construction and completely mixed operation, a CSTR is ... WebMass transfer coefficients are often, although not routinely, measured by photobioreactor developers [3,4,5,6,7,8,9]. Knowing mass transfer capabilities is essential information for judging the potential of a photobioreactor’s geometry to scale its performance when other bottlenecks are removed. easter celebrations cbbc
