Styrene Maleic Anhydride Copolymerization in a Recycle Tubular Reactor: Reactor Stability and Product Quality
Ahstrct-Styrene maleic anhydride copolymers (SMACs) are of particular commercial and academic interest. The bulk copolymer&&ion reaction is characterized by a very fast reaction rate and an important gel effect. The copolymer has a strong tendency to be alternate when maleic anhydride is in excess. In order to obtain a copolymer with less than 50% of incorporated MA, a good quality of mixing mu...
متن کاملV2O5-MoO3 Catalysts Preparation and Performance Testing on the Oxidation of Benzene to Maleic Anhydride in a Fixed Bed Reactor
In this research, the selective oxidation of benzene to maleic anhydride (MAN) in a fixed-bed reactor was studied. The gas phase catalytic oxidation of benzene was carried outin a laboratory scale fixed bed reactor on the catalysts, which were prepared having two different compositions on silica gel. The effects of temperature, flow rates of benzene and air, and catalyst type on the reactio...
متن کاملSimulation, Optimization & Control of Styrene Bulk Polymerization in a Tubular Reactor
In this paper, optimization and control of a tubular reactor for thermal bulk post-polymerization of styrene have been investigated. By using the reactor mathematical model, static and dynamic simulations are carried out. Based on an objective function including polymer conversion and polydispersity, reactor optimal temperature profile has been obtained. In the absence of model mismatch, de...
متن کاملStyrene Biofiltration in a Trickle-Bed Reactor
The biological treatment of styrene waste gas in a trickle–bed filter (TBF) was investigated. The bioreactor consisted of a two-part glass cylinder (ID 150 mm) filled with 25 mm polypropylene Pall rings serving as packing material. The bed height was 1m. Although the laboratory temperature was maintained at 22 °C, the water temperature in the trickle–bed filter was slightly lower (about 18 °C)....
متن کاملSolution Polymeriza Tion of Methyl-methacrylate at High Conversion in a Recycle Tubular Reactor
The kinetics of the solution polymerization of methyl-methacrylate is characterized by a strong increase of viscosity up to 6 orders of magnitude and auto-acceleration of the reaction rate due to the gel-effect. This can lead to thermal and kinetic reactor instabilities. The kinetics were determined separately using a differential scanning calorimeter and described with a modified published mod...
