Primary-reforming catalysts

Making the right choice for a primary reforming catalyst is extremely important as it has a significant effect on the reformer performance, impacting on plant rate, tube life and methane slip.

In this, the most critical operating unit in the ammonia production train, Johnson Matthey manufactures KATALCOTM QUADRALOBE reforming catalysts. QUADRALOBE catalysts are unique in their ability to reform efficiently the full range of feedstocks from natural gas up to heavy hydrocarbons such as naphthas.

They are made in alkalised or non-alkalised variants, with four pellet sizes, allowing optimum reformer loading for each individual plant.
