Catalytic reaction. The catalytic performance was determined at atmospheric pressure for 300 mg of catalyst in a tubular fixed‐bed reactor (8.1 mm diameter, 100 mm length) at a reaction temperature of 275 °C. The reaction setup is shown in Figure 7. This invention is generally directed toward a supported catalyst system useful for polymerizing olefins. The method for supporting the catalyst of the invention provides for a supported metallocene catalyst which when utilized in a polymerization process substantially reduces reactor fouling and sheeting in a gas or slurry polymerization process.

The conventional commercial gas-phase process carries out the conversion in fixed-bed reactors at high pressure. Depending on the catalyst supplier, the synthesis reaction is normally carried out at about 600 to 1,700 psig and 400 to 600°F. Substantial process gas recycle of H 2 rich gas moderates the temperature rise across the adiabatic reactor.  · For this, catalytic mathematical models based on mass and energy balances should be formulated to predict reactor performance and to allow optimum design of catalyst and reactor. This paper deals with a number of issues, which influence the design of packed beds, and on the basis of that significance matters such as selection of particle shape, loading and scaling are addressed here.

 · The incipient point at which the fluid, or gas, flow causes the bed of particles to expand and lift into the vertical column is marked by a conceptually simple balance. At U mf, the hydrodynamic drag force on the particles F d, due to the flow of gas through the packed bed of particles, matches (or just exceeds), the net gravitational forces ... The aim of this study was to design a packed bed reactor incorporating a nanocrystalline foam photocatalyst for VOC remediation in the gas-phase. The reactor has many advantages over existing reactors in that the catalyst can be formed in situ in the reactor; the catalyst is contaminant non-specific and hence can be used for a wide range of ...
