“…The water insoluble fraction is viscous and denser than the water-soluble, and is usually named bio-oil. 4 Bio-oil is a complex mixture of organic compounds with many oxygen-containing functional groups which include acids, aldehydes, ketones, phenols, furans, and sugars. 5 The watersoluble phase predominately consists of low-molecular-weight acids and aldehydes, ketones with high reactivity, as well as phenolic compounds that provide smoky flavors.…”

“…9 Many publications involving one-dimensional and comprehensive gas chromatography (GC × GC) analysis have been reported, with the most varied types of bio-oils. 2,4,6,10,11 Obviously, such approaches required an extraction step due to the unsuitability of water samples in GC. This step, generally operated with dichloromethane, can greatly affect the qualitative and quantitative composition of the sample extracted from the water phase due to the different solvent affinity for each chemical family of the sample.…”

Complementary Analytical Liquid Chromatography Methods for the Characterization of Aqueous Phase from Pyrolysis of Lignocellulosic Biomasses

et al. 2014

In this work, two analytical liquid chromatography methods were developed and compared for the characterization of aqueous phases from pyrolysis of lignocellulosic biomasses. NanoLC electron ionization-mass spectrometry (EI-MS) represents a novel and useful tool for both separation and identification of semi/nonvolatile and thermolabile molecules. The use of nanoscale flow rates, the highly reproducibility, and high detailed information on EI spectra are the principal advantages of this technique. On the other hand, comprehensive 2D-LC, providing a two-dimensional separation, increases the overall peak capacity lowering the occurrence of peak coelutions. Despite the use of reversed phase modes in both dimensions, a satisfactory degree of orthogonality was achieved by the employment of a smart design of gradient elution strategies in the second dimension in combination with photodiode array detection (PDA) and atmospheric pressure chemical ionization-mass spectrometry (APCI-MS). Because of the absence of the preliminary extraction procedure, the fingerprint obtained for these samples results is independent of the extraction yield or contamination contrary to the gas chromatography-mass spectrometry (GC-MS) approach where a liquid-liquid extraction of the water phase is necessary. The main classes of identified compounds were phenols, ketones, furans, and alcohols. The synergistic information on the two powerful analytical approaches, e.g., NanoLC EI-MS and LC × LC, in the identification of such complex samples has never been investigated and fully benefit on the one hand from the superior degree of mass spectral information from EI-MS and on the other hand from enhanced LC × LC compound separation.

“…Huge researchers investigated the influence on temperature on pyrolysis products yield and accomplish the optimal pyrolysis temperature for at higher bio-oil yield extraction. Bertero et al observed that the most favorable temperature of 550 C for pyrolysis of channar and palm yielded up to 35-50% of bio-oil [33]. Jackfruit peel pyrolysis process conducted at 550 C resulted in 32-50% of bio-oil [34].…”

The present investigation emphasis on characteristics of pyrolysis products was obtained by intermediate pyrolysis of Aegle marmelos (AM) deoiled seed cake and appropriateness of engine adaptation. The superior volatile matter (73.69%) contented AM biomass was elected as the feed stock in this study. Pyrolysis experiment was done by a fixed bed reactor at 600°C and obtained 42–55% bio‐oil yield. Investigation of bio‐oil by GC/MS and FTIR established the occurrence of methyl, ester, alkanes, ketones and oxygenated chemicals have been alternates for fossil fuels. SEM and EDX analysis of bio‐char exposes activated carbon and ensured that biochar can be used in the waste water treatment plant, solid fuel, organic fertilizer, and natural mosquito destroyer. According to GC analysis, the presence of CH4, H2, and C2H6 evolved syngas in AM pyrolysis process can be used C.I engines at dual fuel mode operation. An engine test reveals that adding of the pyrolysis oil diminished BTE (%) and increasing BSEC (MJ/kWhr). However, increasing bio‐oil ratio blend with diesel reduces hazardous emissions like CO, HC, NOx, and smoke in the exhaust. Based on engine results, it was proposed that equal to 20% of AM bio‐oil can be used as a fuel substitute for diesel engines. © 2018 American Institute of Chemical Engineers Environ Prog, 38:e13116, 2019

“…Bertero et al conducted the pyrolysis of two palm residues at 550°C in a fixed bed reactor: the pericarp from white palm fruit and the residuals from the extraction of oil from white palm seeds. They reported yields of bio-oil plus tar from 35 to 44 wt% containing 23-35 and 67-77 wt% of phenols, respectively (Bertero et al, 2014). The high amount of phenol, the base of phenols, in the bio-oils of palm oil residues is very interesting because this phenol, if isolated from the bio-oils, may be used to replace the phenol which is currently obtained from petroleum.…”
