At present, in the world, the production of linear alkylbenzenes widely uses UOP DEH-7 dehydrogenation catalysts in the dehydrogenation stage of paraffins. Due to UOP’s monopoly on these catalysts, the manufacturers have not obtained this catalyst regeneration. technology. The regeneration technology of dehydrogenation catalyst DF-3 in Fushun Chemical Plant is the result of research on the deactivation mechanism and regeneration method of domestic dehydrogenation catalyst.
The success of the rejuvenation experiment will completely solve the difficult problem of poor strength of the domestic dehydrogenation catalyst carrier, and the problems of carrier and active component reuse, high catalyst cost, etc. will be resolved simultaneously, and the production cost of the enterprise product will be greatly reduced.
Fushun Petrochemical's dehydrogenation catalyst regeneration experiment succeeded
On January 18th, the Fushun Petrochemical Company's DF-3 dehydrogenation catalyst in a petrochemical plant was regenerated for 50 days. The data showed that the performance was fully met and the experiment was successful.
