Flow-through reactor system

In addition, a secondary screening HT method is well suited to test the catalytic properties of materials using a parallel flow-through reactor system (i.e. the Multi Fixed Bed Reactor System—MFBR) fitted with parallel detection and quantification techniques by MS and GC [32-35],...

To find the conversion for the reactor, we need the average reaction probability for a great many molecules that have flowed through the system. The averaging is done with respect to residence time since residence time is what determines the individual reaction probabilities ...

Extraction System. The flow-through extraction system used in this study is shown in Figure 1. The system is operable up to 400 bar at 200°C. It consists of solvent delivery systems (Fluid 1, Fluid 2, Fluid 3), a flow-through reactor (FR), a set of separator traps (TP1, TP2), and the temperature and pressure control units. The reactor, traps, micrometering valves, and tubing connections are housed in a heated oven. 

Flow through Reaction System. The feed naphtha was pumped from the oil feed tank, T-1, on scale to the preheater, B-2, and thence to the bottom of the reactor, D-1, which was 45 feet long.

The apparatus consists of a flow through extraction system that can be operated at pressures up to 400 bar and temperatures up to 200°C. This apparatus was described elsewhere (2). Its main piece is a 19 cm3 reactor, where 4-5 g of 40-60 mesh milled cork were placed between two G3 fritted glass discs. The reaction mixture is expanded into a series of three 35 cm3 precipitation traps. A dual-head high pressure liquid pump was used to compress the solvent. One pump head was cooled with ice to pump liquid C02 while the other pump head was used for 1,4-dioxane.

The mechanism of particle formation at submicellar surfactant concentrations was established several years ago. New insight was gained into how the structure of surfactants influences the outcome of the reaction. The gap between suspension and emulsion polymerization was bridged. The mode of popularly used redox catalysts was clarified, and completely novel catalyst systems were developed. For non-styrene-like monomers, such as vinyl chloride and vinyl acetate, the kinetic picture was elucidated. Advances were made in determining the mechanism of copolymerization, in particular the effects of water-soluble monomers and of difunctional monomers. The reaction mechanism in flow-through reactors became as well understood as in batch reactors. Computer techniques clarified complex mechanisms. The study of emulsion polymerization in nonaqueous media opened new vistas. 

The system of beds is entirely similar to that of the stirred tanks shown in Fig. 5.18. A fraction of the initial flow is preheated and passed to the reactor R, and the rest is split between the beds. Kq is the flow through reactor r whose inlet and exit conditions are denoted by c [Pg.121]

To perform a macroscopic species balance, we conduct a species balance over an entire reactor. Consider an arbitrary reactor with one inlet and one outlet and volume shown schematically in Figure 4.1a. Fluid flows through the system, and chemical reactions take place inside the system. We impose no restrictions on the system except the assumption that the chemical reactions are homogeneous (i.e., they take place throughout the system).
