RNG methanation

The final step

In the RNG methanation process step, the final conversion of carbon monoxide, carbon dioxide and hydrogen into the RNG product takes place.

In Topsoe’s TREMP™ RNG process, the catalysts MCR-2 and MCR-8 are used for methanation at high temperatures, while the PK-7R catalyst is used for methanation at lower temperatures.

Catalysts and equipment for RNG methanation

MCR-8 catalyst

Nickel-based methanation catalyst for medium to high-temperature applications in RNG plants.

MCR-2 catalyst

MCR-2 is used in combination with the GCC-2 gas conditioning catalyst in the TREMPTM process.

PK-7R catalyst

PK-7R is a pre-reduced ring-shaped methanation catalyst for conversion of carbon oxides to methane.

Boiling water reactor

The boiling water reactor is typically used for methanol synthesis, but it can also be used for other exothermic reactions.

Applications within this area

RNG gas conditioning

In the gas conditioning step, part of the carbon monoxide present in the process gas reacts with steam forming carbon dioxide and hydrogen while releasing heat.

RNG feed purification

In the feed purification process step, the final removal of contaminants takes place.
