High-pressure reactors are versatile laboratory reactors that can be used for hydrogenation, organic compound synthesis, polymerization, and additional chemical reactions under pressure.
They can also be utilized in petrochemical research, new material testing, and other fields of research and industry that demand high pressure.
The laboratory pressurized reactor comes in sizes ranging from 25 ml to 5000 ml. Some series of high-pressure reactors are composed of AISI 316Ti / Hastelloy S-276 alloy and AISI 316L stainless steel or. Protective inserts made of PTFE or glass are available.
A high-pressure reactor's maximum working temperature can range from 250 to 500 degrees Celsius. A magnetic stirrer or a laboratory hotplate is used to heat reactors with volumes up to 500 ml; a heating mantle and advanced temperature control systems are utilized for reactors with sizes of 700 ml and higher.
Overhead stirrers equipped with magnetic couplings allow effective (high-viscosity) mixing. Magnetic stirrers are usually sufficient for capacities up to 500 mL.
Because the relevant processes (such as reactions, heat, and/or component transport) normally demand adequate contact and homogeneity of the existing phases, the mixing system of a mixed tank is always a significant design feature.
With the use of appropriate models, practical knowledge may be expanded, leading to a better understanding of reactor behavior and the macro mixing phenomenon.
Local hydrodynamic circumstances influence crystallization events in stirred reactors and these must be considered for scaling up and optimizing the process.
BENEFITS
Gas-phase, solid-phase and heterogeneous catalyst technology all benefit from the use of corrosion-resistant gradient-less reactors, which are standard equipment in the field.
This pressurized reactor apparatus is suitable for a variety of supported and selective catalyst research, such as catalyst screening, characterization, and surface chemical studies.
The leak-proof metal gasket design enables scientific research with bench-scale catalytic synthesis.
What is a stirred reactor's major function?
Stirred reactors are frequently employed for solid/liquid/gas or solid/liquid reactions wherein the solid catalyst is stopped in powder form in a liquid that may be an inert or one of the reactants.
Mechanically stirred reactors are the most frequent reactor type in laboratories for slurry systems, although they have a number of drawbacks in terms of industrialization.
Mechanically stirred reactors, which are commonly utilized in lab investigations, are difficult to scale up. Bubble columns must be operated at a high space velocity to obtain excellent mixing and mass transfer between the gas and slurry phases, resulting in a low one-through conversion of the syngas.
A riser, a down-comer, a gas-liquid separator, a gas distributor, and specifically designed internals for mass transfer and heat removal intensification comprise the reactor.
The slurry phase circulates in the reactor due to the density difference between the riser and the down-comer.
Even at a low superficial gas velocity, a favorable flow structure can be obtained, and heat and mass transmission can be intensified.

So that was everything about pressurized reactors and some useful information.
