Alkali promoted tubular reforming catalyst
High alkali catalyst for steam reforming of naphtha feedstocks.
RK-202 is used in tubular reformers for steam reforming of naphtha feedstocks. RK-202 is installed below the prereduced version RK-212 and above a low alkali catalyst like RK-201.
The alkali content on the RK-202 and RK-212 catalysts has been optimized and is generally lower than seen for other alkali-promoted catalysts on the market. Since the alkali has a negative impact on the catalyst activity, the relatively low alkali content is preferable to ensure a high activity of the catalyst. Still, the alkali content on the RK-202 and RK-212 catalysts is sufficiently high to ensure carbon free operation in a steam reformer. The alkali content is so low that fouling of waste heat boilers basically can be excluded.
