Pseudoboehmite, hailed as the pillar of the catalyst industry, plays a crucial role in numerous fields. From petrochemicals to environmental catalysis and energy conversion, this important catalyst support material exhibits unique physical and chemical properties, making it an indispensable component of modern industrial catalysis.

Applications in the Petrochemical Industry

Pseudoboehmite is often used as a catalyst support in refining processes such as hydrodesulfurization and denitrification. Its unique properties optimize pore size distribution and enhance the dispersion of active components. It is also used in the preparation of liquefied tin-based catalysts and precious metal-supported catalysts, such as hydrogenation catalysts. Its high surface area and acidic sites significantly improve reaction efficiency. In the catalytic cracking (FCC) process, pseudoboehmite acts as a binder, enhancing catalyst strength and regulating pore size distribution.

Applications in Environmental Catalysis

Pseudoboehmite also performs well in environmental catalysis. It is often used as a coating support for automotive exhaust treatment catalysts (such as three-way catalysts), effectively improving the conversion efficiency of harmful gases such as CO and NOx. It is also suitable for industrial waste gas purification, playing a significant role as an adsorbent for removing VOCs (volatile organic compounds).

Applications in Molecular Sieve Synthesis

In molecular sieve synthesis, pseudoboehmite not only serves as an aluminum source and binder but also improves the mechanical strength and thermal stability of the molecular sieve catalyst. Furthermore, it can even be used directly as a catalyst in reactions such as ethylene oxide synthesis and alcohol dehydration to ethylene, further broadening its application range.
