Taylor‐vortex membrane reactor for continuous gas‐liquid reactions

چکیده
A unique Taylor-vortex membrane reactor (TVMR) design for continuous gas-liquid reactions is presented in this work. The consists of a cylindrical rotor inside stationary concentric vessel, and flexible system equispaced baffle rings surrounding the rotor. This restricts annular cross section to small gap between baffles rotor, divides annulus into 18 mixing zones. support 6 m long PFA tubular that woven around At 4 mL/min inlet flow rate, TVMR showed plug-flow behavior outperformed unbaffled reactor, having 5–12 times lower axial dispersion. aerobic oxidation benzyl alcohol was performed 7 h using Pd(OAc)2/pyridine catalyst toluene at 100 °C 1.1 MPa oxygen pressure. stable conversion 30% achieved with 85% benzaldehyde selectivity, no pervaporation organics gas phase.

High-Temperature Membrane Reactor for Catalytic Gas-Solid Reactions
A mathematical model, based on the dusty-gas model extended with surface diffusion, is presented that describes mass transport owing to molecular diffusion and viscous flow, as well as an instantaneous reversible reaction inside a membrane reactor. The reactants are fed to opposite sides of the membrane, considering masstransfer resistances in the gas phase outside the membrane. The Claus react...
متن کاملReactor modeling and kinetic parameters estimation for diethylbenzene (DEB) dehydrogenation reactions
Divinylbenzene (DVB) is produced by catalytic dehydrogenation of DEB at high temperature and atmospheric pressure. Ethylvinylbenzene (EVB) is produced as a useful chemical during dehydrogenation of DEB. Also some other liquid and gaseous by products is produced during dehydrogenation. A set-up has been developed to conduct the DEB dehydrogenation reactions experiments to prepare DVB at differen...
متن کاملMATLAB Simulation for Continuous Stirred Tank Reactor
This paper presents control of the nonlinear system represented by a Continuous Stirred Tank Reactor (CSTR) using MATLAB’s Graphical User Interface (GUI). This simulation provides computation for various values of the input variables, which made this program universal for the wide range of the users without theoretical knowledge about modeling, simulation, and control.
