Product Overview

The Micromeritics Flow Reactor series is a highly advanced modular laboratory system for determining the selectivity and activity of catalysts. They are compact, robust and versatile platforms designed to save time and resources at the catalyst development stage and accelerate process scale-up. Benchtop reactors feature a high-temperature furnace, up to six mass flow controllers and patented pressure control valve for stable accurate pressure control of multiphase streams up to 200 bar. The thermostated environmental chamber eliminates cold spots and prevents condensation of vapour streams.

The FR features an innovative and flexible user interface that allows users to easily define catalyst activation, reaction studies and cyclic sequences for determining catalyst lifetime. The intergrated touch screen can be used to define and control process parameters allowing users easy access.

The FR100 reactor is configurable for comprehensive catalyst reaction studies. If your research requires more flexibility for complex processes, the FR200 muti-reactor system provides the capabilities to study muti-step catalytic processes. Safety features include secure door lock, alarms, and automated shut-off valves. The modular design of the FR systems is customisable with options such as additional gas and liquid feeds, bypass and switching valves, interchangeable reactor materials and sizes, gas analysers and sensors and more.

The patented auto high-pressure liquid gas separator can separate gas from liquid at operating pressure with very low dead volumes providing real-time results with reproducibility and accuracy. It is the most advanced separator for reactions containing multi-phase products and allows independent separation of two non-miscible liquids such as hydrocarbons and water.

A wide range of reactions can be accommodated including hydrocracking, hydrotreating, isomerisation, hydrogenation, hydrodesulphurization (HDS), oxidation, hydrodenitrogenation (HDN), reforming (aromatization), GTL (Fischer-Tropsch), and steam reforming. These benchtop reactors are also ideal for research studies on topics such as biofuels, methane activation or sustainable reactions.

  • The latest advancement in studying catalytic reactions is the high-pressure liquid-gas or liquid-liquid gas separator for studying catalytic reactions
  • Small footprint saves expensive lab space and optionally allows installation within a fume hood
  • Automated routines minimise user errors and reduce test time
  • Expandable for future needs, e.g. detectors or optional accessories (e.g. GC/MS, additional gas and liquid feeds, Liquid Liquid Gas (LLG) separator, others upon request) that protects your investment


  • Fischer-Tropsch synthesis – liquid hydrocarbons and wax

Liquid fuels and other chemical products can be produced from syngas (a mixture of hydrogen and carbon monoxide) via the well-known and catalytic chemical process called Fischer-Tropsch (FT) synthesis.

  • Ammonia synthesis/ decomposition

The Haber-Bosch process is an artificial nitrogen fixation process and is the main industrial procedure for the production of ammonia today.

  • Methanol synthesis and higher alcohols

One route to produce methanol is characterisaed by the addition of carbon dioxide to hydrogen.

  • Steam/ Dry reforming 

Steam methane reforming (SMR) is a process in which natural gas is heated with steam to produce a mixture of carbon monoxide and hydrogen used in organic synthesis.

  • Sabatier process – methane production

Sabatier process produces methane and water from a reaction of hydrogen with carbon dioxide at elevated temperatures.

  • Hydrogenation and dehydrogenation

Hydrogenation is a chemical reaction between hydrogen and another compound usually in the presence of a catalyst.
