“…Furfural, D-allose and phenolic compounds are the main chemical compounds in the bio-oil for the three kinds of biomass. Similar results were reported in our previous research [23,32] and the work of Mahinpey [5]. Properties and chemical composition of bio-oil are distinct from petroleum fuel because of its relatively high content of water and solids, acidity and instability when heated [26].…”

“…Up to date, the existing literature has only focused on the characterizations of biochar or bio-oil. With respect to studies of two or more energy carriers, Mahinpey et al [23] examined the influence of pyrolysis pressure on product yield from wheat straw pyrolysis. Uzun et al [21] studied the characteristic and quantities of bio-oil and biochar from the pyrolysis of tea waste.…”

a b s t r a c t a r t i c l e i n f oThe pyrolysis of three representative sources of biomass, namely, white ash, switchgrass and corn stover were investigated using a fixed-bed reactor to observe and compare the characterizations of three energy carriers, biochar, syngas and bio-oil. The characteristics of biochar were determined by Fourier Transform Infrared Spectroscopy (FT-IR), X-ray diffractometer (XRD) and Scanning Electron Microscopy Energy Dispersive Spectroscopy (SEM-EDS), Gas Chromatography (GC) and Gas Chromatography Mass Spectrometry (GC-MS).The results showed that the carbon content of biochar increased with the increase of pyrolysis temperature. More than 52 wt.% of the carbon was captured in the biochar. The infrared spectra of char samples illustrated that various bands in the spectra were identified, corresponding to stretches -NH-, aliphatic stretches -CH-, stretches conjugate -C_C-, -CH 3 and stretches -C\ \O-. The surface morphology of biomass sample changed after pyrolysis and carbon fiber can be formed at the temperature of 500°C. The content of combustible gas CH 4 , H 2 and CO was changed from 50% to 70%. The GC-MS analysis of bio-oil showed that most of the chemical compounds detected were phenolic ones. This study provides a useful reference for energy carriers from the pyrolysis of biomass.

“…Li et al (2013b) extracted 12.7 wt% levoglucosan from bio-oil using water. However, the macromolecular oligomer of coniferyl, synapyl, and p-coumaryl alcohols hindered further separation and application of bio-oil (Kim et al 2010). The use of the other techniques also has been limited as a result of the presence of large amounts of medium molecular weight compounds (500 < Mn < 3000) in pyrolysis oil (Mahfud et al 2008).…”

“…Decomposition of lignin took place over a broad temperature range (200 °C to 500 °C), because of the various oxygen functional groups in its structure that result in different thermal stabilities (Brebu and Vasile 2010). Nevertheless, the decomposition of hemicellulose, cellulose, and lignin was difficult to differentiate distinctively (Kim et al 2010). From DTG (Fig.…”

An attempt was made to chemically modify palm kernel shell (MPKS) to increase adsorption affinity towards Reactive Black 5 (RB5). Granulated palm kernel shell (PKS) was quaternized successfully by treating with N-(3-chloro-2-hydroxypropyl)trimethylammonium chloride under alkaline conditions and was characterized. Surface characterization by Scanning Electron Microscopy (SEM) and BET analysis confirmed the surface pore enlargement from mesospores to macropores after modification. Fourier Transform-Infrared (FTIR) Spectrometer and CHN analysis revealed that the quaternary ammonia group (NR 4 + ) was successfully reacted on MPKS fiber. pH 4 is the optimum for removal of RB5 on MPKS. Equilibrium isotherms were analyzed by the Langmuir, Freundlich, and Redlich-Peterson models. The Redlich-Peterson model was found to fit well with the data. The maximum adsorption capacity of MPKS was 207.5 mg/g for adsorption of RB5.
