Used as a catalyst support in refining and petrochemical processes due to its high surface area and thermal stability. Common in hydrocracking and hydrotreating units where it helps disperse active metal components like nickel, molybdenum, or cobalt. Also serves as a binder in catalyst formulations, improving mechanical strength and attrition resistance. Applied in adsorbents for gas purification and in ceramics for producing alumina-based materials with controlled porosity. Used in coatings and refractory products for enhanced durability and heat resistance.
