    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-2 catalyst for RNG methanation

    MCR-8 catalyst

    Nickel-based methanation catalyst for medium to high-temperature applications in RNG plants.
    MCR-2 catalyst for RNG methanation

    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 catalyst

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

    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.
