“…The chemical structures of the pyrolysis products of lignins have been evaluated by gas chromatography/mass spectrometry (GC/MS) [10][11][12], nuclear magnetic resonance (NMR) [12][13][14][15][16][17][18] and infrared (IR) spectroscopic [15,[19][20][21] analyses, along with pyrolysis directly coupled with GC/MS [22][23][24][25][26][27][28][29][30][31][32][33][34][35] and IR [19,[36][37][38][39] (Py-GC/MS, Py-IR). Aromatic methoxy groups are stable during the primary pyrolysis stage and become very reactive in the temperature range of 400-450 °C.…”

“…Fast pyrolysis of the lignin produced monomeric phenolic compounds and oligomers with different degrees of polymerization [32][33][34][35]. It is believed that the lignin-derived products are mainly responsible for the high molecular weight and viscosity of bio-oils, and thus, one of the aims of using catalysts in the pyrolysis process is to crack these products into lighter ones.…”

Catalytic Upgrading of Biomass Fast Pyrolysis Vapors with Nano Metal Oxides: An Analytical Py-GC/MS Study

Fast pyrolysis of poplar wood followed with catalytic cracking of the pyrolysis vapors was performed using analytical pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS). The catalysts applied in this study were nano MgO, CaO, TiO 2 , Fe 2 O 3 , NiO and ZnO. These catalysts displayed different catalytic capabilities towards the pyrolytic products. The catalysis by CaO significantly reduced the levels of phenols and anhydrosugars, and eliminated the acids, while it increased the formation of cyclopentanones, hydrocarbons and several light compounds. ZnO was a mild catalyst, as it only slightly altered the pyrolytic products. The other four catalysts all decreased the linear aldehydes dramatically, while the increased the ketones and cyclopentanones. They also reduced the anhydrosugars, except for NiO. Moreover, the catalysis by Fe 2 O 3 resulted in the formation of various hydrocarbons. However, none of these catalysts except CaO were able to greatly reduce the acids.

The composition used for model calculations here is therefore a representative one based on typical information from a number of researchers, and does not pretend to be an accurate model of a particular product.…”

“…The main components are organic acids, aldehydes, ketones, phenols, anhydrosugars such as levoglucosan, pyrolytic lignin (comprising guaiacyl-and syringylbased fragments of the original lignin polymer) and substantial quantities of water, typically 25% [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Usually only trace amounts of hydrocarbons are present, the vast majority of the components being oxygenates.…”

This paper presents a numerical model for the evaporation and pyrolysis of a single droplet of pyrolysis oil derived from biomass. Continuous thermodynamics theory for multicomponent droplet evaporation is used, with the fuel being represented by four fractions: organic acids, aldehydes/ketones, water, and pyrolytic lignin, each of which is described by a separate distribution function. Pyrolysis of the lignin fraction is included, and detailed properties for all fractions are presented. The model is compared with the results of suspended droplet experiments, and is shown to give good predictions of the times of the major events in the lifetime of a droplet.
