Abstract

Different SBA-15 (SBA, Santa Barbara Amorphous) materials were synthetized at different temperature and time during of the hydrothermal treatment. The obtained SBA-15 were characterized by N2 adsorption isotherms, scanning electron microscopy (SEM), X-ray diffraction (DRX), and density in order to establish the influence of these variables on their properties. Mixtures of the obtained catalysts with 3R4F tobacco were prepared and smoked under the ISO 3308 conditions. Temperature of the hydrothermal treatment slightly affects the tars that evolved in the smoking process of the corresponding catalyst tobacco mixtures. Contrarily, the time of the hydrothermal treatment has a marked effect on the reductions of toxic compounds in the smoke. Developed porosity has a positive correlation with the observed tar reduction, whereas the apparent density has a negative correlation with the reduction in toxicity. Moreover, the removal of the supernatant liquors during the hydrothermal treatment does not strongly modify the properties of the materials and may represent an interesting simplification of the process.

Highlights

A large amount of studies focused on determining the effect of tobacco on human health.Since before the 1980s, it has been known that the habit of consuming tobacco is the main cause of lung and oral cancer [1,2]
The main objective of this study is to determine the effect of the variables of synthesis of the SBA-15 and the textural properties developed on the reduction of toxic compounds of tobacco smoke
SBA-15 synthesized in this study show good developed behavior as catalysts collected the of thethe hydrothermal treatment temperature

Summary

Introduction

Since before the 1980s, it has been known that the habit of consuming tobacco is the main cause of lung and oral cancer [1,2]. Until the last few decades, no great efforts had been made to reduce the consumption of tobacco through campaigns of awareness about the effects of smoking on health, increasing costs, or prohibiting consumption in certain places [5,6,7]. In this respect, the percentage of the smoking population has been reduced, many people still consume tobacco
