Product introduction

The solid phosphoric acid catalyst is mainly used for the oligomerization of propylene to produce nonene and dodecene, and the superposition of carbon tetraolefins to produce high-octane gasoline, and it can also be used for the alkenization of benzene and propylene to produce cumene, etc.

Solid phosphoric acid catalyst has the characteristics of good catalytic activity, high oligomer selectivity and strength, strong mud resistance, long service life and wide application range.

It's performance has reached the advanced level of similar catalysts at home and abroad. The solid phosphoric acid catalyst produced by AVANT is currently mainly exported to foreign countries, and has been successfully applied in many sets of industrial devices around the world.

Product Basic Info

Solid phosphoric acid catalysts are widely used in catalysis, propylene oligomerization and benzene alkylation reactions. It is generally believed that the active component of the solid phosphoric acid catalyst is the free phosphoric acid on the surface of the catalyst, which belongs to the protonic acid catalyst.

The activity of solid phosphoric acid catalyst is not only related to the total amount of free acid, but also related to the acid strength distribution of the catalyst.
