“…A large number of researches have been focused on producing high quality bio-oil, and one of the most attractive methods is catalytic fast pyrolysis (CFP) technology [2][3][4][5]. A range of zeolite catalysts has been researched in the literatures [6][7][8], and previous experimental results have confirmed that ZSM-5 zeolite performs the best to de-oxygenate pyrolysis vapors and favor hydrocarbon production [9][10][11].…”

“…The main thermal decomposition products of cellulose are anhydrosugars, pyranone and furan derivatives and oxo compounds [13,20,21]. Relative peak areas (normalized to unit sample mass) of some volatile pyrolysis products of the cellulose component of beech and pine wood samples and of their mixtures with PVC are presented in Fig.…”

Thermal decomposition of polyvinylchloride (PVC) -wood and wood component mixtures were examined under slow and fast heating by pyrolysis-gas chromatography/mass spectrometry (Py-GC/MS) and thermogravimetry/mass spectrometry(TG/MS) techniques in order to clarify the chemical interaction of biomass materials and PVC during thermal decomposition. A hardwood and a softwood (beech and pine), their lignin and two types of cellulose (Avicel and Whatman) were chosen as natural polymer components. Comparing the gaseous and liquid pyrolysis products of pure samples to those of mixtures it was found that considerably lower amount of several reactive compounds have been produced when the biomass sample was mixed with PVC. On the other hand significant amount of chloromethane appeared in the pyrolysate of wood and lignin samples mixed with PVC under fast and slow pyrolysis conditions as well, but only in traces of chlorinated organic compounds were detected from cellulose mixtures. It was concluded that the methoxy groups at phenolic rings in lignin are the methyl source of chloromethane formation, and this reaction consumed most of the HCl evolved from PVC.

“…Cellulose decomposition consists of two competitive reaction channels: the formation of tars (mainly LG) and char, and the formation of light gases (Capart et al 2004). In an investigation of the mechanism of the cellulose pyrolysis and the formation of the main products, Wang et al (2012) found that LG and other anhydrohexoses are formed directly from cellulose, and that these anhydrosugars can further decompose into furfural and acids. The pyrolysis of cellulose is divided into three stages: 150 to 300 °C, 300 to 390 °C, and 380 to 800 °C.…”

Levoglucosan (LG) obtained from lignocellulosic biomass exhibits great potential as a specific tracer for biomass burning aerosols and as a raw material for synthesizing stereoregular polysaccharides. One potentially viable source of LG is pyroligneous acid (PA). This study investigated the effects of heating temperature on the extraction capability and the chemical composition of distillate and residual fractions. The results demonstrated that vacuum distillation extracted the acids, alcohols, ketones, aldehydes, and other organic matter. When the heating temperature was above 80 °C, the moisture content of the residual fraction was unchanged. The chemical composition of residual fraction was analyzed by gas chromatography-mass spectrometry (GC-MS). The analysis showed that the relative content of the LG, as obtained from the 90 °C distillation temperature, was 75.6%. Thus, it can be used as raw material for subsequent purification.
