Applications:

Pseudoboehmite features high phase purity, excellent peptization properties, strong binding ability, high specific surface area, large pore volume, and improved stability capable of withstanding higher processing temperatures. It possesses unique chemical characteristics of an aluminum oxide hydrate with a special spatial network structure that undergoes thixotropic peptization under acidic conditions. In the petroleum industry, it is used as a catalyst carrier and binder. The catalyst carrier acts as the skeleton for the active components of a catalyst, supporting and dispersing them while also enhancing the catalyst's mechanical strength. The carrier itself lacks catalytic activity. It is used for loading chemicals, heavy metals, rare metals, precious metals, etc., primarily embodied in products such as oxidation catalysts, hydrogenation catalysts, dehydrogenation catalysts, hydroformylation catalysts, polymerization catalysts, hydration catalysts, dehydration catalysts, alkylation catalysts, isomerization catalysts, disproportionation catalysts, etc. This product is manufactured using various pseudoboehmite raw materials with different indices (low sulfur, sulfur-free, high silicon, low silicon, high purity, low sodium, small pores, large pores, etc.) via a rolling granulation process.
