In the fields of industrial waste gas treatment and air purification, H₂S (hydrogen sulfide) and VOCs (volatile organic compounds) rank among the most common and challenging pollutants to treat. While traditional adsorption materials often suffer from issues such as low removal efficiency and short service life, potassium permanganate-impregnated activated alumina has emerged as a core […]

In the modern petrochemical, refining, and environmental protection industries, the performance of a catalyst depends not only on its active components but is also closely linked to the catalyst support material employed. Selecting an appropriate support can significantly enhance catalytic efficiency, extend service life, and reduce operating costs. Among the multitude of available materials, activated […]

I. Core Functions of Inert Support Spheres Inert support spheres are mainly used at the bottom of fixed-bed reactors or below the catalyst bed. Their core functions include: · Supporting the catalyst bed: preventing catalyst particles from collapsing or leaking. · Optimizing gas and liquid distribution: improving the uniformity of the reaction medium. · Protecting […]
