    Catalytic fast pyrolysis of biomass with mesoporous ZSM-5

    This study investigated the effects of desilication of ZSM-5 zeolite on its catalytic properties in catalytic fast pyrolysis (CFP) of lignocellulosic biomass. A series of mesoporous ZSM-5 zeolites were prepared by desilication of a conventional microporous ZSM-5 zeolite with NaOH solutions of varying concentrations (0.1–0.5 M).

    The pathway of biomass catalytic pyrolysis process using the ZSM-5(con.), ZSM-5, and ZSM-ST catalysts. The results presented herein therefore show that the ZSM-5(con.) catalyst contains a limited number of mesopores, which results in the polymerization of bulky oxygenates to form coke on the surface, thereby preventing the reactants from

    MCM-41/ZSM-5 composite particles for the catalytic fast

    ZSM-5 is a promising catalyst for the catalytic fast pyrolysis (CFP) of biomass due to its high selectivity to light hydrocarbons. However, rapid deactivation of catalyst has been a major challenge towards the commercialization of CFP. The objective of our study is to evaluate the performance of MCM-41/ZSM-5 composites during the CFP of biomass.

    Ga/ZSM-5 catalyst improves hydrocarbon yields and increases

    Catalytic fast pyrolysis using the zeolite ZSM-5 is an attractive process for converting lignocellulosic biomass into fuels and chemicals. Ga-modified ZSM-5 has demonstrated improved hydrocarbon yields compared to ZSM-5 due to additional functionality imparted by Ga; however, there is little knowledge of the 2020 Green Chemistry Hot Articles

    Biomass catalytic fast pyrolysis over hierarchical ZSM-5

    Hierarchical ZSM-5 and Beta zeolites, loaded with MgO and ZnO, have been explored for the catalytic fast-pyrolysis of eucalyptus woodchips. These materials exhibit a high dispersion of the MgO or ZnO phases, which is probably due to the presence of a hierarchical porosity with both micro- and mesopores in the zeolitic supports.

    Therefore, the performance of mesoporous aluminosilicate materials was inferior to ZSM-5 zeolites when previously tested for the catalytic fast pyrolysis of biomass waste. A range of high acidity Al-SBA-15 catalysts have been synthesised using a novel synthesis method which achieved acidities comparable to ZSM-5.
