Guide On Mechanism Of High-Pressure Autoclave Reactor

High-Pressure Autoclave Reactor An autoclave is a pressure vessel with exact temperature and pressure controls. In it, various materials can be processed by managing the intricate curing reactions according to time, temperature, and pressure profiles.

Reactors called hydrothermal autoclaves which carry out hydrothermal reactions at higher temperatures and pressures. Two kinds of hydrothermal reactors are used, one of which is the PPL lines autoclave and the other of which is Teflon or PTFE. The autoclave reactors position both of them parallel to one another. 

What are High-Pressure Autoclave Reactors?

The autoclave reactor is a compact cylindrical reactor designed to resist extreme pressures used to study the kinetics of high-temperature, high-pressure processes and produce small quantities of specialized compounds.

In terms of construction, it differs from an autoclave due to its size. High-pressure autoclaves are built to withstand pressures much more than 100 bar. Therefore, the material’s characteristics made it strong enough to support such a load. Every connection, including valves, measurement tools, and closures, is carefully made for use in high-pressure and temperature applications.

How does the Autoclave Reactor perform?

The kinetics of high-temperature, high-pressure reactions are monitored as well as the manufacture of small amounts of specialized chemicals in the autoclave reactor, a small cylindrical reactor designed to endure high pressure. The reactant is often added via injection, and the reactor is usually filled with a supported catalyst. 

The autoclave’s temperature is raised, which raises pressure within the system. Gaseous reactant or an inert can then be injected to create additional pressure, if necessary. 

This reactor makes it simple to collect data from high-temperature, high-pressure reaction systems with complex flow characteristics. Solid reactants or combinations of solids and liquids fall within this category at room temperature. Coal liquefaction, petroleum residuals, and coal liquids upgrading, and large molecular weight hydrogenation studies are typical autoclave reactions. 

How to operate Hydrothermal Autoclave Reactors?

  • Place the autoclaving or sterilizing equipment on the table.
  • The primary screw-type threaded SS cap (SS Alloy 304) should be turned anti-clockwise until it opens.
  • The white milky-coloured PTFE/Teflon reaction chamber should be removed by lifting the lid or top SS gasket.
  • Before sealing the reaction chamber, the solvent should be poured into the liner based on its capacity.
  • The Teflon cap must be airtight to avoid pressure leaking.

It is crucial to ensure the Teflon-lined vessel is correctly positioned in the Stainless Steel chamber and to maintain the top gasket over the container.

The primary SS cap should be turned clockwise when it can no longer turn any further.

A secondary SS cap has been provided at the top of the primary cap for extra tightening to avoid pressure leaks.

The primary SS cap can be turned clockwise with locking rods to tighten it even more.

  • The hydrothermal autoclave should be placed in the furnace or oven and heated until the reactor reaches a safe temperature.
  • The oven’s temperature should be raised, and the heating pace should be limited to 5° C per minute.
  • The researcher can heat the hydrothermal autoclave to 200 C for safe use.
  • After the hydrothermal synthesis reaction, the autoclave will cool at a rate of 5 C/minute.
  • After the operation, the Teflon liner or PTFE should be saturated.
