TK-41
TK-41 has very high affinity for arsenic trapping in VGO and gas oil services, where it is also ...
Originating in processed crude oil, arsenic has long been recognized as a severe catalyst poison. Compared to other contaminants, arsenic is a genuine poison, since it actively titrates the working catalytic sites by forming NiAs or CoAs.
Topsoe offers a number of highly efficient arsenic-trap catalysts that catch and accumulate arsenic many times more effectively than conventional hydrotreating catalysts. These arsenic guards can also be used effectively as part of a tailored hydrodemetallization (HDM) solution.
