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.

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

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).

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....
