Abstract
In the secondary reformer, high density, high alumina (99% & more) refractory used in hot face from the burner down to the diffuser cone and to the catalyst dome support. High Alumina hexagonal target tiles are commonly used in the secondary reformer as bed topping media. Refractories are subjected to severe reducing atmosphere, Corrosion, Thermal Gradient and Load Deformation. Therefore the refractory has to be made specially with high purity & careful selection of raw materials & adequate process control. The high alumina content, low impurity such as silica and high strength of high alumina refractory is ideal for high temperature and steam applications. Processing of high alumina refractories discussed here with various high purity raw material aggregates. Effect of Sintering temperatures vis-à-vis mechanical strength properties studied. Characterisation of microstructural properties and thermo-mechanical properties of developed high alumina refractory shared in this paper. |
