| Description | Parr offers a number of different reactors in the 4570 and 4580 Series in a variety of sizes and with different mountings for operating pressures to 5000 psi (345 bar) and temperatures to 500 °C. All of these reactors have been designed with suitable valves, fittings and modifications to the vessel Parr offers a number of different reactors in the 4570 and 4580 Series in a variety of sizes and with different mountings for operating pressures to 5000 psi (345 bar) and temperatures to 500 °C. All of these reactors have been designed with suitable valves, fittings and modifications to the vessel itself to operate at the higher temperature and pressure ratings. Flat, flexible graphite (FG) gaskets are used for temperatures in the higher range to 500 °C. These can be replaced with PTFE gaskets for procedures in which the temperature will not exceed 350 °C. All cart and floor stand models use ceramic fiber heaters to achieve the higher operating temperatures....

This type of system can support reaction schemes including but This system incorporates three tubular reactors that can be configured as required to operate in a strictly parallel fashion or in a cascade arrangement where the products from one reactor are immediately directed to a second reactor. This type of system can support reaction schemes including but not limited to the Fisher-Tropsch process, methanation reactions, steam reforming and other similar processes.
The Fisher-Tropsch process converts carbon monoxide and hydrogen into oils or fuels that can substitute for petroleum products. The reaction uses a catalyst based on iron or cobalt and is fueled by the partial oxidation of coal or wood-based materials such as ethanol, methanol, or syngas. This reaction scheme offers a promising route to producing economical renewable transportation fuels. By carefully controlling the temperature and oxygen content, resulting products can range from syngas to “green diesel”....

ASTM G170 describes the use of a rotating cage (RC) for such testing. Parr can provide a complete high pressure, high temperature RC system (pictured) which typically includes the following components: - Reactor system made of Alloy C276 or other corrosion resistant alloy, with included rotating cage
- Gas feed system to deliver CO2, H2S, or N2
- Liquid feed system to deliver acid or inhibitor
- Reflux condenser and pressure controller
- Automated or manual control and data logging system
Pressure and temperature ratings, reactor volume, material of construction, number of gas and liquid feeds, and control system specifics can be customized to meet individual testing requirements....

They can be furnished with either a self-sealing, O-ring closure for working temperatures up to 225 °C or with a flat, PTFE gasket for higher temperatures to 350 °C. An optional HP (High Pressure) flat gasket version has been added for maximum allowable working pressure of 2900 psi (200 bar) at 350 °C. Both fixed head and moveable vessel designs are available. An optional pneumatic lift is available for the heavier 2 liter cylinder and heater.
With their larger diameter, these mid-size reactors have sufficient space for special modifications, such as: an internal cooling coil, bottom drain valve (not on 2 liter bench top), ball valve for a solids charging port, catalyst addition devices, condensers, electrical feed-throughs and more.
The standard magnetic stirrer drive on these 4520 Models works well for reaction mixtures with viscosities up to 25,000 centipoise. For heavier stirring loads, these reactors can be equipped with larger magnetic drives, more powerful motors, and drive trains capable of delivering additional stirring torque.... Read More |
