“…This maximum aliphatic hydrocarbon value found in this study was higher than those reported in earlier studies [3,30]. In addition, the maximum aliphatic hydrocarbon content found in this study was much higher than the maximum hydrocarbon content in pyrolysis products obtained from other types of biomass [31][32][33]. This might be due to the fact that higher amounts of lipids in Schizochytrium limacinum are converted into aliphatic hydrocarbons during pyrolysis [21].…”

Pyrolysis-gas chromatographic mass spectrometry (Py-GC/MS) was used to determine the yield and chemical composition of the pyrolysis products of Schizochytrium limacinum. The pyrolysis was carried out by varying the temperature from 300 °C to 800 °C. It was found that the main decomposition temperature of Schizochytrium limacinum was 428.16 °C, at which up to 66.5% of the mass was lost. A further 18.7% mass loss then occurred in a relatively slow pace until 760.2 °C due to complete decomposition of the ash content of Schizochytrium limacinum. The pyrolysis of Schizochytrium limacinum at 700 °C produced the maximum yield (67.7%) of pyrolysis products compared to 61.2% at 400 °C. While pollutants released at 700 °C (12.3%) was much higher than that of 400 °C (2.1%). Higher temperature will lead to more pollutant (nitrogen compounds and PAHs) release, OPEN ACCESSEnergies 2013, 6 3340 which is harmful to the environment. Considering the reasonably high yield and minimum release of pollutants, a lower pyrolysis temperature (400 °C) was found to be optimum for producing biofuel from Schizochytrium limacinum.

“…There have been many studies on the pyrolysis of CC (Cao et al 2004;Feng et al 2006;Ates and Isikdag 2009;Ioannidou et al 2009;Zhang et al 2009;Trninic et al 2012;Liu et al 2014). Most of these studies focused on developing kinetics models to predict the weight loss characteristics of CC and the reaction dynamics, and only a few were concentrated on the emission regularities of bio-syngas products (consisting primarily of CO, CO2, CH4, and H2) during the pyrolysis as well as on the key factors affecting the thermal degradation.…”

The influence of heating rate, gas flow, and biomass particle size on the pyrolysis and thermal dynamics of corncobs (CC) was investigated experimentally using the quantitative method of thermogravimetric analysis (TGA) coupled with mass spectrometry (MS), and the obtained results were compared in depth. For the examined heating rates of 5, 10, and 20 °C/min, the CC pyrolysis at higher heating rates resulted in a more complete decomposition. The initial pyrolysis temperature decreased when gas flow was increased from 30 to 90 mL/min, whereas the weight loss increased. Particle sizes (d ≤ 74 μm, 74 μm < d ≤ 154 μm, 154 μm < d ≤ 280 μm, and 280 μm < d ≤ 450 μm) had pronounced effects on the thermal decomposition and bio-syngas compounds (CO, CO2, CH4, and H2) distribution. The emission intensities of most the gaseous products increased at the elevated heating rate, while they decreased with increasing gas flow. In sum, the pyrolysis of CC particles of 154 μm < d ≤ 280 μm under 20 °C/min and in a gas flow of 30 to 60 mL/min was the most appropriate for bio-syngas production in industrial applications.

“…Similar result was also reported for corncob catalytic pyrolysis. By using H-ZSM5, increase of pH from 2.8 (without catalyst) to 5.2 (with catalyst) was achieved [18]. Reduction of acid, ester and alcohol content may contribute to the increase of pH value of bio-oil.…”
