“…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]. These disadvantages limit the use of bio-oil.…”

“…These results indicated that there were some mineral crystals such as MgO and CaCO 3 in the biochar [22]. The existence of alkali metals (Na, K, Ca and Mg) in the biochar was reported in our previous work [26,27].…”

“…These results indicate that biochar has potential as an amendment to neutralize soil acidity [22]. The alkali metals of Na, K, Ca and Mg were detected in biochar in our previous study [26]. Although more volatiles were released with the increase of pyrolysis temperature, the alkali metals were difficult to volatile in the biomass pyrolysis process.…”

“…In previous research, the kinetic analysis of biomass pyrolysis [24,25] and the characterizations of biochar, syngas and bio-oil were investigated [26,27]. The main objective of this research was to investigate the characteristics of biochar, syngas and bio-oil from slow pyrolysis of white ash wood, switchgrass and corn stover at the temperature range from 300°°C to 500°°C.…”

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.

“…In the previous research, the liquid production from the pyrolysis of biomass [15,16] and sewage sludge [17,18] were investigated. The present contribution reports a non-isothermal TGA study of the pyrolysis in N 2 and CO 2 -gasification of six representative CSW samples, aiming to identify the key thermal events during the CSW gasification process.…”
