Primary Reforming Catalyst
The HHZ01 primary reforming catalyst is used in primary reformers to synthesize hydrogen or ammonia by steam or methane-containing gases, such as natural gas, refinery gas, associated petroleum gas, coke oven gas and so on.
Feature
This steam reforming catalyst takes aluminum oxide, calcium oxide, magnesium oxide and other oxides as its carrier, while nickel oxide works as the major active component, thus imparting some excellent properties, such as high mechanical strength, simple reduction and loading, good low temperature activity, good resistance to carbon forming, etc.
Conforming to HG2273.1-2004 standard, our natural gas reforming catalyst contains different models, and these catalysts differ from each other in technical performance. As a result, different catalyst combinations could be selected according to specific process flow and tube design, thereby offering optimized catalytic effect.
