Christy's CUSTOM-CRAFTEDTM Hexagonal Target Tiles are now used in over 50 ammonia plant secondary reformers. While being specified by KBR in their process, the tiles are also used in any design such as Haldor Topsoe or Uhde reactors with a central riser.
Made of low silica alumina refractory mix, the hexagonal target tiles lock in to each other to provide very high lateral stability in the face of turbulent gas velocities. The extremely durable 99% alumina formula also provides superb erosion resistance.
A ring of Christy's unique circle brick around the perimeter prevents gas bypass around the outside edges of the hexagonal target tile array.
The most recent improvement is the massive SUPER JUMBO hexagonal target tile, which at 90 mm thick and 22 kg presents the ultimate in stability and in thermal protection of the catalyst underneath.
The concept of a massive tile as reactor topping is not restricted to secondary methane reformers, but is also applicable to other reactors with high temperatures and/or high horizontal velocities.
