    Physicochemical properties and catalytic performance of galloaluminosilicate in aromatization of lower alkanes: a comparative study with Ga/HZSM-5

    A series of gallium-containing HZSM-5 zeolites with different Ga contents (Ga/(Al+Ga) = 0.1–0.6) were prepared by hydrothermal in situ synthesis and post synthesis. Their catalytic performance were compared in...

    Silica nanoboxes from alumina rich zeolites: thermal and chemical stability of the monomodal and bimodal materials

    Silica nanoboxes synthesized from alumina-rich zeolites, showed two distinct categories of nano-structured materials. Entirely mesoporous nanoboxes (monomodal Al-nanoboxes) were highly thermally and chemically...

    New method for the study of surface acidity of zeolites by NH3-TPD, using a pH-meter equipped with an ion selective electrode

    Desorbed ammonia is captured by an acetic acid solution whose concentration of ammonium ions formed by neutralization, is continuously recorded by a pH-meter equipped with an ion-selective electrode (ISE). Thi...

    The Thermocatalytic Cracking Process for the Production of Light Olefins and Transportation Fuels from Gas Oils

    The thermocatalytic cracking (TCC) process, which can selectively produce light olefins (mostly, ethylene and propylene for the petrochemical industry) and transportation fuels (gasoline and diesel fuel), comb...

    Silica Nanoboxes as New Nano-structured Materials: Their Secondary Synthesis from Alumina-Rich Zeolites

    Novel silica nanoboxes were prepared by controlled dealumination of Na-X and Ca-A type zeolites using ammonium hexafluorosilicate (AHFS). The silica-richer the parent zeolite, the smaller the average pore size pr...
