Features
1. High- performance product modified with promoters, taking iron oxide as active component, chromic oxide as structure modifier.
2. Suitable for high velocity and lower steam/ dry gas ratio operating conditions, excellent low- temperature activity, enable increasing of production capability and energy saving.
3. Excellent selectivity, suppressing the generation of by-products, such as hydrocarbons and alcohols.
4. Excellent mechanical strength to avoid breaking during operation. Long service life.
5. Low bulk density, reducing catalyst dosage.
6. Excellent sulfur resistance performance.
7. Strong adaptability and good operating flexibility.
8. It has low bulk density, low weight of catalyst that can be filled for the same charge volume, can reduce costs.
9. It has low-temperature activity for increased production and energy savings.
