Coagulation in a Continuously Stirred Tank Reactor
Smoluchowski 's coagulation equation with coagulation rates K 0 oc (ij) ~ describing the temporal evaluation of the size distribution ck (concentration of k-mers) is studied in the presence of a source term ark, and a sink term --bCk. With a' a/b 2 one finds that a steady state is reached, exhibiting gelation when w > 1⁄2 and a ' > ao(w), where a0(o~) depends on w (ao(w) = ~ for ~o < 1⁄2, ao(1)...
متن کاملMechanisms of increased methane production through re-circulation of magnetic biomass carriers in an experimental continuously stirred tank reactor
Magnetite particles were used in a semi-continuous process as magnetic biomass carriers to separate and reintroduce microorganisms in a CSTR reactor. In comparison to a control reactor the methane content during the semi-continuous process was elevated when magnetite particles were used. The difference was most apparent during the fermentative step directly after feeding and upon direct spiking...
متن کاملBifurcation Phenomena for an Oxidation Reaction in a Continuously Stirred Tank Reactor. Ii Diabatic Operation
We extend an investigation into the bifurcation phenomena exhibited by an oxidation reaction in an adiabatic reactor to the case of a diabatic reactor. The primary bifurcation parameter is the fuel fraction; the inflow pressure and inflow temperature are the secondary bifurcation parameters. The inclusion of heat loss in the model does not change the static steady-state bifurcation diagram; the...
متن کاملBiogas production from different substrates in an experimental Continuously Stirred Tank Reactor anaerobic digester.
Different mixtures were digested in a single-stage, batch, mixed, laboratory scale mesophilic anaerobic digester at the Biomass Research Centre Laboratory (University of Perugia). The yield and the composition of biogas from the different substrates were evaluated and the cumulative curves were estimated. Two experimental campaigns were carried out, the first on three mixtures (chicken, pig and...
متن کاملDetermination of Methane and Carbon Dioxide Formation Rate Constants for Semi-Continuously Fed Anaerobic Digesters
To optimize commercial-scale biogas production, it is important to evaluate the performance of each microbial step in the anaerobic process. Hydrolysis and methanogenesis are usually the rate-limiting steps during digestion of organic waste and by-products. By measuring biogas production and methane concentrations on-line in a semi-continuously fed reactor, gas kinetics can be evaluated. In thi...
