“…The amount of oxygen in the final products is consequently higher than what is observed with “normal cigarettes” and favors the formation of oxygenated MSS compounds. As the composition of the biomass content of the cigarette is different, the investigation of MSS by LDI and ESI FTICR‐MS in negative detection mode may give relevant information as we demonstrated on the study of bio‐oil generated from biomass pyrolysis . The investigation of Indonesian and Kretek MSS by (−) LDI gives additional insights into the contribution of cloves to the final products observed in the MSS particle phases.…”

“…Compounds with up to eight oxygen atoms are observed and the center of the Gaussian distribution is shifted to O5–O6 species. Such C x H y O w distributions have still been evidenced in the study of bio‐oil produced by pyrolysis of lignin or biomass and are relevant to the thermal degradation of the lignin, cellulose and hemicellulose of the biomass . The C x H y O w species observed in the study of Kretek MSS correspond to the superposition of the pyrolysis products of tobacco (O2 to O5), which typically contains 10% of cellulose, 12.5% of sugars and 3.5% of lignin and the pyrolysis of the cloves (O4 to O8), which is a ligno‐cellulosic material and contains close to 60% of cellulose and sugar .…”

“…The increase in the laser fluence generally leads to a recombination phenomenon which may be associated with the clustering phenomenon . To increase the knowledge of the composition of the cigarette smoke particle fraction, electrospray ionization (ESI) may be regarded as a complementary ionization technique as recently demonstrated for bio‐oil analysis . Indeed, the ability of ESI to efficiently ionize polar compounds, which are poorly detected by LDI, may be helpful to obtain a more complete description of such complex samples.…”

Rationale:The chemical composition of the particulate phase of cigarette smoke inhaled by the active smoker is still poorly known in spite of its importance from a health point of view. A non-targeted approach is applied to cigarette smoke particles collected on a quartz filter to obtain an as complete as possible description of this complex mixture.Methods: A home-made smoking machine including devices for volatile organic compounds (VOCs) and particle sampling was used. The validation of the cigarette smoking and cigarette smoke collection procedures was conducted by the quantification of some compounds by gas chromatography/mass spectrometry (GC/MS). The particles were investigated by Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS) directly after their collection on quartz filters by laser/desorption ionization (LDI) or after extraction with CH 2 Cl 2 by electrospray ionization (ESI). Results: The determination of the benzene, toluene, ethylbenzene and xylenes (from 2 to 35 μg/cigarette) and nicotine (0.68 ± 0.05 mg/cigarette) validated the used sampling method. The complementarity of the LDI and ESI sources for the cigarette smoke analysis was established. The ESI analyses evidenced polar compounds and components with a pyridine group and LDI ensured the detection of polycondensed heteroaromatic species. Finally, this methodology was employed to characterize particles from cigarettes with or without flavoring additives. Conclusions: Some insights into the composition of cigarette smoke inhaled by active smokers have been obtained. The~1750 observed features revealed the huge complexity of cigarette smoke particles and the diversity of the possible associated health issues. Both heteroaromatic and highly oxygenated compounds produced by combustion and pyrolysis have been highlighted.

“…Textural properties are often optimized by using nano-sized particles and introducing mesoporous structure to increase specific surface area and enhance reactant diffusion [16,18,19]. For example, hierarchical zeolites (HZ) have been widely used recently [20,21]. Due to the intercrystalline mesopores in bulk particles and large openings on the particle surface, the diffusion performance is optimized.…”

The industrial utilization of lignocellulosic biomass is often accompanied by lots of lignin residues. Catalytic fast pyrolysis (CFP) is a high-throughput method to convert lignin to aromatics and phenolics. In order to optimize catalytic performance, conventional zeolite catalysts often need to have mesostructural modification. Here, based on hierarchical zeolite (HZ), a novel micro-mesoporous composite zeolite was obtained by redeposition under mild conditions. The conversion of two industrial lignin residues, Kraft Lignin (KL) and Pyrolytic Lignin (PL), was investigated. Interestingly, the hierarchical sample was more suitable for the case of higher concentration of primary pyrolysis products such as CFP of PL, with aromatics yield of 12.7 wt % and a monocyclic aromatic hydrocarbons (MAHs) to polycyclic aromatic hydrocarbons (PAHs) mass ratio of 4.86. The mesoporous composite zeolite possessed a better PAHs suppression capability as M/P reached 6.06, and was suitable for low reactants’ concentration and high oxygen content, such as KL CFP, with a higher aromatics yield of 3.3 wt % and M/P of 5.12. These results were compared with poplar sawdust as actual biomass, and mesoporous samples were both highly efficient catalysts with MAHs yield over 10 wt % and M/P around 5.

“…A more recent type of zeolitic catalysts, the so-called hierarchical zeolites, which exhibit both the improved diffusion properties of mesoporous materials and the strong acidity and stability of zeolites [72][73][74], has also been investigated in biomass CFP [75][76][77][78][79][80][81]. However, few studies have been reported so far on lignin CFP.…”

Catalytic Fast Pyrolysis of Lignin Isolated by Hybrid Organosolv—Steam Explosion Pretreatment of Hardwood and Softwood Biomass for the Production of Phenolics and Aromatics

Lignin, one of the three main structural biopolymers of lignocellulosic biomass, is the most abundant natural source of aromatics with a great valorization potential towards the production of fuels, chemicals, and polymers. Although kraft lignin and lignosulphonates, as byproducts of the pulp/paper industry, are available in vast amounts, other types of lignins, such as the organosolv or the hydrolysis lignin, are becoming increasingly important, as they are side-streams of new biorefinery processes aiming at the (bio)catalytic valorization of biomass sugars. Within this context, in this work, we studied the thermal (non-catalytic) and catalytic fast pyrolysis of softwood (spruce) and hardwood (birch) lignins, isolated by a hybrid organosolv–steam explosion biomass pretreatment method in order to investigate the effect of lignin origin/composition on product yields and lignin bio-oil composition. The catalysts studied were conventional microporous ZSM-5 (Zeolite Socony Mobil–5) zeolites and hierarchical ZSM-5 zeolites with intracrystal mesopores (i.e., 9 and 45 nm) or nano-sized ZSM-5 with a high external surface. All ZSM-5 zeolites were active in converting the initially produced via thermal pyrolysis alkoxy-phenols (i.e., of guaiacyl and syringyl/guaiacyl type for spruce and birch lignin, respectively) towards BTX (benzene, toluene, xylene) aromatics, alkyl-phenols and polycyclic aromatic hydrocarbons (PAHs, mainly naphthalenes), with the mesoporous ZSM-5 exhibiting higher dealkoxylation reactivity and being significantly more selective towards mono-aromatics compared to the conventional ZSM-5, for both spruce and birch lignin.
