    for optimal performance


    Low temperature shift catalyst

    LK-801 is TOPSOE™’s first generation LTS catalyst. Similar to our other LTS catalysts, it is based on oxides of copper, zinc, and aluminum. 


    LK-801 is used in ammonia and hydrogen plants for the conversion of carbon monoxide via the water-gas shift reaction.

    Competitive performance 

    The activity of LK-801, though not as high as that of TOPSOE™’s standard and premium LTS catalysts, has demonstrated its ability to optimize plant performance for decades at numerous plants worldwide.

    High mechanical strength

    LK-801 and its successors (LK-821-2, LK-823 and LK-853 FENCE™) are manufactured to ensure the highest possible crush strength, resulting in a low and stable pressure drop throughout the catalyst lifetime.
