A Laboratory reactor is designed for the optimization and reproduction of various chemical reactions, dispersal, mixing, and homogenizing processes. Applications of laboratory reactors include mixing and drying powders, developing lotions and creams, fuel research, and fiber processing in liquids and polymers. Key considerations for laboratory reactors are primarily dependent on the types of reactions taking place (polymerization, hydrocracking, etc). Other considerations include flow rate, temperature range, volume, and pressure range.

| Description | Single-phase flow in a tubular reactor can be upward or downward. Two-phase flow can be co-current up-flow, counter-current (liquid down, gas up) or, most commonly, co-current down-flow.
Tubular reactors can have a single wall and be heated with an external furnace or they can be jacketed for Single-phase flow in a tubular reactor can be upward or downward. Two-phase flow can be co-current up-flow, counter-current (liquid down, gas up) or, most commonly, co-current down-flow.
Tubular reactors can have a single wall and be heated with an external furnace or they can be jacketed for heating or cooling with a circulating heat transfer fluid. External furnaces can be rigid, split-tube heaters or be flexible mantle heaters. Tubular reactors are used in a variety of industries: - Petroleum
- Petrochemical
- Polymer
- Pharmaceutical
- Waste Treatment
- Specialty Chemical
- Alternative Energy

The distinguishing feature of a fluidized bed reactor is that the solids bed or catalytic particles are supported by an up flow of gas. This reactor provides easy loading and removing of catalyst. This is Parr Fluidized Bed Reactors are used extensively in the chemical process industries. The distinguishing feature of a fluidized bed reactor is that the solids bed or catalytic particles are supported by an up flow of gas. This reactor provides easy loading and removing of catalyst. This is advantageous when the solids bed must be removed and replaced frequently. A high conversion with a large throughput is possible with this style of reactor. Such reactors inherently possess excellent heat transfer and mixing characteristics.
Fluidized beds have been significantly utilized in chemical processes, in which parameters such as diffusion or heat transfer are the major design parameters. Compared to packed bed, a fluidized bed has notable advantages such as better control of temperature, no hot spot in the bed, uniform catalyst distribution and longer life of the catalyst. The desirability of using fluidized beds is dependent on achieving good mixing between the solids and the suspending fluid.
Features - A gas handling and mixing sub-system used to blend and regulate the flow of reactant gas to the bottom of the reactor.
- The reactor is roughly one meter long with a 2.5 cm ID. The lower portion of the reactor incorporates an easily replaced porous metal gas diffusion plate and the top of the reactor widens abruptly to form a disengaging zone for the fluidized bed.
- Separate heaters are provided for both the main reactor and disengaging zone. A multipoint thermocouple is provided for monitoring the internal reactor temperature distribution.
- A heated cyclone separator or filter is provided immediately downstream of the reactor to capture the fines resulting from particle attrition.
- The reaction products are then cooled by a condenser and collected in a 600 mL product receiver.
- The system pressure is maintained by a dome loaded back pressure regulator.
- All system functions and parameters are monitored and maintained by a Parr 4871 Process Controller (not shown).

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....
