Alkali promoted tubular reforming catalyst
Low alkali pre-reduced catalyst for steam reforming.
RK-400R is used in tubular reformers for steam reforming of feedstocks ranging from natural gas to LPG. RK-400R is pre-reduced and installed on top of RK-400 and a non-alkali catalyst like R-67-7H.
Latest generation of low alkali catalysts
The RK-400R catalyst is the latest generation of Topsoe’s low alkali catalysts and offers remarkable improvements in both catalyst activity and resistance to carbon formation compared to conventional alkali-promoted products.
RK-400R is delivered pre-reduced and in addition to potassium, are also promoted with a noble metal. This feature of the catalyst makes it especially suited for the inlet conditions in a steam reforming furnace, where low temperatures are prevailing. The superior ability of RK-400R to operate at the low temperatures in the top of the catalyst tube is the result of a special manufacturing technique and the addition of a noble metal promoter. An additional advantage is that the catalysts have been reduced in Topsoe’s production facilities in dry hydrogen at an optimal temperature, which results in higher activity than what could be obtained by in-situ reduction.
