Carbon monoxide high temperature conversion catalyst

It should have the main technical characteristics of high activity, high strength, low water vapor ratio, high inhibition capacity of iron carbide generation, high water resistance, low heap density, low sulfur content and so on:

1. High activity; High CO conversion rate.

2, high use strength can ensure long operation cycle, bed resistance is not increased.

3. Under the condition of low water vapor ratio, it can inhibit the formation ability of iron carbide.

4, high water resistance can save time for customers, save catalyst procurement costs.

5. Low heap density.

6, low sulfur content.

7. The heating reduction time should be as short as possible.

At present, the domestic heap density of this kind of catalyst is high, about 1.6kg /L. By improving the manufacturing process, the catalyst with the bulk density of 1.25Kg/L can be produced to ensure the performance of the catalyst. In addition, these catalysts are seldom suitable for low water vapor ratio. It is very rare for the manufacturers to have a good performance in large fertilizer plants under low water vapor ratio conditions. It is ideal to ensure that the catalyst can operate at a minimum water vapor ratio of 0.35.

Changing catalyst

Carbon monoxide low temperature conversion catalyst

It should have advanced production technology, low temperature and high activity, low reactor density, high operating intensity after reduction, high selectivity and effective inhibition of alcohol generation, and the final product does not contain physical water and other technical characteristics.

1. At present, this kind of catalyst is a copper-zinc-aluminum series product produced by the world's most advanced copper-ammonia complex process.

2. At present, most manufacturers use wet materials to dry in the oven, and then crush them, add water and graphite to make sheets. By changing the manufacturing process, the catalyst has a low bulk density of about 1.2Kg/L.

3, good selectivity, can effectively inhibit the generation of alcohols.

In short, a new round of large-scale chemical fertilizer projects in China has provided a broad market for carbon monoxide conversion catalysts. Catalyst manufacturers should seize this favorable opportunity, introduce advanced technology, use advanced manufacturing materials, and better improve the performance of catalysts is a feasible way to expand the market.
