The reactor can even Stirring biomass such as straw or grasses is not easy to do in a vertical reactor. A line of reactors has been developed by Parr Instrument Company to function horizontally. These new reactors are secured vertically for loading and then safely tilted horizontally for stirring. The reactor can even be designed to tilt upside down for discharge. Horizontal reactors can be designed for capacities ranging from 0.1 liter to 10 liters. The larger systems can be controlled pneumatically to tilt the system upright to open the bottom drain valve. These horizontal rectors can obtain temperatures up to 350 °C and maximum pressures of 1900 psig....

With reactor volumes of 5 mL or 10 mL, independent reactor gas filling, PID temperature control, and a choice of two closure styles, the flexibility of the The Series 2500 Micro Batch Reactor System is the smallest of Parr's family of stirred reactors and is available in a number of configurations. With reactor volumes of 5 mL or 10 mL, independent reactor gas filling, PID temperature control, and a choice of two closure styles, the flexibility of the MBS 2500 is sure to bring value to your small volume, high pressure project. Based on the popular Parr MRS 5000, the MBS 2500 offers even smaller volume options, a smaller footprint, a stand-alone control and data logging system, and a lower per reactor price. Features of the Micro Batch System 2500 include: - Three reactors with 5 mL or 10 mL volume, available in stainless steel, high-nickel alloys, titanium, zirconium, and other exotic materials
- Small 10” x 12” (25 cm x 30.5 cm) footprint, with remotely located 4848-based controller for temperature/stirring control and pressure display.
- Standard 3000 psi (207 bar, 200 bar for CE orders) @ 300 °C rating in T316 Stainless Steel
- Trusted Parr seal geometry employing either a captive PTFE flat gasket and screw cap with compression bolts, or a self-sealing O-ring with tool-free screw cap closure
- Standard head fittings to include safety rupture disc, pressure transducer, inlet/vent valve, and internal thermocouple
- 3-valve inlet manifold for control of gas addition
- Common aluminum block heater with PID control
- Individual reactor temperature monitoring
- Individual reactor pressure monitoring
- Common stirring speed via individual PTFE-or Pyrex-encapsulated stir bars

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”....

Although they are called “Mini” reactors, they offer a range of sizes large enough to work with significant sample sizes, yet small enough to be handled with ease by all operators. They are made in both fixed head and moveable vessel styles, These are the most popular of all Parr Stirred Reactors. Although they are called “Mini” reactors, they offer a range of sizes large enough to work with significant sample sizes, yet small enough to be handled with ease by all operators. They are made in both fixed head and moveable vessel styles, with a choice of either a self sealing O-ring closure with no cap screws for working temperatures up to 225 °C, or with a flat, PTFE gasket for higher temperatures up to 350 °C sealed with six cap screws in a split-ring cover clamp.
Choosing the high temperature option (HT) boosts the maximum temperature to 500 °C, but de-rates the MAWP to 2000 psi (138 bar). Standard Mini reactors can be converted to high temperature reactors (500 °C max temperature and 2000 psi MAWP) by changing the head openings to cone connections, replacing the valves with high temperature valves, replacing the gasket with a graphoil Flat Gasket, replacing the heater with a ceramic fiber heater, and replacing the split ring. Contact Parr for details.
Although internal and external space is limited in these small vessels, gas entrainment impellers, catalyst baskets, condensers and other options are available. All reactors in this series can also be easily converted from one size to another by simply substituting a longer or shorter cylinder with the corresponding internal fittings and heaters....
