Pt Based Propane Dehydrogenation Catalyst

Preparation method of Pt based propane dehydrogenation catalyst

Impregnation: Impregnation is the most common method for loading precious metals onto supports

Ion exchange method: The principle of this method is to use the interaction of noble metal precursors with hydroxyl groups on the surface of the support

Sol-gel method: The sol-gel method is a common method for preparing catalysts.It is generally used to prepare metal oxide catalysts and supported non-precious metal catalysts. The preparation of the noble metal catalyst by the method can prevent the sintering of the noble metal particles to a certain extent.

Sedimentation precipitation method: The precipitation precipitation method is a method in which the carrier is placed in the Pt precursor solution, and different means are used in the stirring process to make the Pt precipitate and deposit on the surface of the carrier.

Product Features of Pt based propane dehydrogenation catalyst

① The catalyst has high activity and low carbon deposition rate. The actual unit consumption of producing propylene reaches 1.17 tons.The catalyst carbon deposition rate is reduced to ensure the benign operation of the regenerator and the performance of the catalyst

② Excellent catalyst chlorine holding performance and catalyst regeneration performance.Low chlorine injection, excellent chlorine holding performance ensures high Pt dispersion.The lower chlorine injection amount reduces the corrosion to the equipment and prolongs the service life of the dechlorination agent

Unique catalyst design enables suitable scorch behavior and ensures good regeneration performance

③ Pt based propane dehydrogenation catalyst has excellent fluidity, strength and anti-wear performance.The catalyst has good sphericity, excellent fluidity, and is not prone to flow stagnation.Good catalyst strength and less dust

Less dust volume can slow down the clogging of the screen and delay the increase of pressure drop, which is beneficial to the long-term operation of the device
