This video explains the components and operation modes of the Frontier Tandem Micro-Reactor for the rapid and accurate evaluation of various catalysts.

What is the Tandem Micro-Reactor?
The reactor is designed to evaluate the effects of various operational parameters on a catalyst's lifetime and performance, which is important for industries involved in waste plastic recycling, energy, and biomass feedstock.

It consists of two main parts, both individually temperature-controlled:

Pyrolysis Furnace (First Reactor): Pyrolyzes feedstock (gases, liquids, or solids like plastics or biomass) to generate gaseous products.

Catalyst Reactor (Second Reactor): Volatiles from the first reactor flow into the second reactor via carrier gas, where they react with the catalyst.

The final reaction products flow into a Gas Chromatograph (GC) for analysis, and the catalyst is evaluated based on the compounds formed.

Demonstrated Operation Modes
The video demonstrates two main modes of operation:

Real-Time Monitoring (Example: Ethanol to Ethylene)

As the reaction temperature is raised, the amount of ethanol sharply drops when the temperature reaches 280°C.

Above 300°C, the desired product, ethylene, is produced.

Stepwise Temperature Mode (Example: Ethanol to Ethylene)

This mode uses a separation column in the GC oven.

By heating the second reactor in steps (e.g., 100, 250, 300, and 400°C), chromatograms are obtained that clearly indicate how the distribution of ethanol, ethylene, and other species changes as the temperature increases.

Isothermal Temperature Mode (Example: Jatropha press cake to BTX)

This mode uses a single set temperature (e.g., 550°C) for the first and second reactors.

The sample is pyrolyzed, the pyrolyzates undergo catalytic reaction, and the products are trapped and then analyzed by a mass spectrometer.
