    Influence of the time of and stirring rate during the first step of synthesis of SBA-15 on its catalytic effect for reducing toxicants concentration in tobacco smoke

    JUÁREZ-SERRANO N.; ASENSIO-MORANT J.; MARTÍNEZ-CASTELLANOS I.; BERENGUER D.; BLASCO I.; BELTRÁN M.I.; MARCILLA A.
    University of Alicante, Alicante, Spain
    Certain mesoporous materials can modify notably the composition of smoke tobacco, since they can act as catalysts and/or adsorbents allowing to reduce the toxic and carcinogenic compounds of the smoke. However, the properties of the catalysts strongly ...

    Effect of SBA-15 morphology in the composition of the mainstream tobacco smoke

    MARTÍNEZ-CASTELLANOS I.; MARCILLA A.; BELTRÁN M.I.; BERENGUER D.; BLASCO I.; JUAREZ N.; ASENSIO J.; CALABUIG E.
    University of Alicante, Alicante, Spain
    Mesoporous silica materials, such as SBA-15, are attracting increasing interest in the last years. Our research group has focused in their capability for reducing the toxic compounds generated in the smoking process when mixed with tobacco. By tuning the ...

    Effect of the addition of SBA-15 in the pyrolysis of a reference tobacco under inert and oxidizing atmosphere

    CALABUIG E.; MARCILLA A.; BELTRÁN M.I.
    University of Alicante, San Vicente del Raspeig, Spain
    The composition of evolved products from slow pyrolysis under inert and oxidizing atmospheres of a reference tobacco 3R4F from the Reference Cigarette Program of the College of Agriculture of the University of Kentucky and a mixture of the reference ...

    Influence of the time of synthesis of SBA-15 on its effect as a catalyst reducing toxicant concentration in tobacco smoke

    JUÁREZ-SERRANO N.; MARCILLA A.; BELTRÁN M.I.
    University of Alicante, San Vicente del Raspeig, Spain
    In recent years, SBA-15 has been suggested as an additive for reduction of toxic compounds in tobacco smoke. The structure of this type of materials is strongly dependent on the synthesis conditions. The objective of the present work is to analyze the ...

    A CFD model for the smouldering combustion of the cellulosic substrate during the ignition propensity test

    GUINDOS P.(1); PATEL A.(1,2); KOLB T.(1)
    (1) Fraunhofer Institute for Molecular Biology and Applied Ecology IME, Aachen, Germany; (2) TU Braunschweig, Braunschweig, Germany
    An experimental and numerical investigation was conducted to characterise the influence of the cellulosic substrate used to assess the ignition propensity (IP) of cigarettes. The objective was to better understand the poor repeatability of the test and ...
