Promoted catalyst carrier get more and more application. In here, we will introduce the industrial application of promoted catalyst carrier.

The catalyst carrier-alumina has its excellent properties after modification, its acidity is low, the thermal stability is good, the selectivity of the catalyst is obviously improved, and the dispersion of the active group on the catalyst has also been improved, the catalyst is a good repeat of the small test results, selectivity also increased by 10% or more. The catalyst carrier dozens of industrial amplification production can be required to obtain a stable physical properties.
By the use of the plant’s praise, its performance over foreign products. The pre-propane pre-hydrogenation catalyst prepared using the modified catalyst carrier was used in domestic industrial plants in April 2001. The catalyst was operating normally and showed good selectivity.

To verify the effect of the catalyst carrier on the catalyst life, a set of regeneration tests were designed as follows:
The green oil was collected at the outlet of the industrial hydrogenation reactor and the catalyst prepared by the method of 1.2 was immersed in the process of repeated soaking and regeneration. The properties of the sample were listed in the following table:

It can be seen from the above data, the use of modified catalyst carrier made of hydrogenation catalyst, after repeated regeneration remains stable, the surface catalyst carrier modification can greatly extend the catalyst life cycle and life. The industrial application of promoted catalyst carrier is very good welcomed.
