In conventional hydrogen and ammonia plants, the final conversion of CO to H2 occurs across the low-temperature shift (LTS) catalyst. This makes the LTS catalyst one of the most important catalysts in the plant — even small changes in its performance will have a significant impact on operating costs, says Kristina Svennerberg, marketing manager, shift and synthesis catalysts at Haldor Topsøe...
