The catalytic performance in n-hexadecane hydrocracking of a set bifunctional catalysts composed acidic mesoporous silicas, i.e., SBA-15, MCM-41, MCM-48, and amorphous silica-alumina (ASA), Pd as acid (de)hydrogenation components, respectively, was investigated. selectivity to cracked products the occurrence secondary cracking depended on pore topology, acidity, dispersion. Si/Al ratio mesopore...

Introduction Nopol is an unsaturated alcohol useful for the synthesis of fragrances, pesticides and household products [1]. It has been traditionally obtained by condensation of β-pinene and paraformaldehyde at high temperatures or using homogeneous Lewis acid catalysts [2]. Recently, heterogeneous catalysts: FePO4, Sn-MCM-41 and Zn-Al-MCM-41, have been reported for nopol synthesis under mild c...

The production of conjugated C4–C5 dienes from biomass can enable the sustainable synthesis many important polymers and liquid fuels. Here, we report first example bimetallic (Nb, Al)-atomically doped mesoporous silica, denoted as AlNb-MCM-41, which affords quantitative conversion 2-methyltetrahydrofuran (2-MTHF) to pentadienes with a high selectivity 91 %. incorporation AlIII NbV sites into fr...

The effect of the surfactant template cetyltrimethylammonium bromide (CTAB) in MCM-41 on the adsorption of aniline was investigated. Various MCM-41 samples were prepared by controlling template removal using an extraction method. The samples were then used as adsorbents for the removal of aniline from aqueous solution. The results showed that the MCM-41 samples with the template partially remov...

Tandem catalysis for the hydrogenation rearrangement of furfural (FA) provides an attractive solution manufacturing cyclopentanone (CPO) from renewable biomass resources. The CuNi/Al-MCM-41 catalyst was synthesized and afforded excellent catalytic performance with 99.0% conversion 97.7% selectivity to CPO in a near-neutral under 2.0 MPa H2 at 160 °C 5 h, much higher than those on other molecula...
