The HHZ03Y heat resistant reforming catalyst is a new type of calcined thermal protection catalyst in the shape of Raschig ring, and its major active component is nickel oxide. The carrier is fabricated through calcination at elevated temperature of over 1500℃, thereby offering good resistance to deformation. Moreover, the large overall dimension ensures excellent heat storage property and heat shock resistance, while the nickel oxide realizes pre-reforming to some extent.
Advantage
As mentioned above, our nickel based reforming catalyst is in the form of Raschig ring, so it is not likely to change its position even under the impact of high speed gas flow. But, alumina spheres and porous spheres tend to move easily when high speed gas stream is fed, and this is a result of their mobility.
It has already been field-proven that catalyst beds will sink downward in the middle of their surface when using spherical reforming catalyst, and this is observed in most manufacturing plants, if not all of them. However, if our chemical fertilizer catalyst is adopted, most parts of the catalyst bed will be flat as ever when unloading catalyst.
