“…The DAEM has been used to describe the pyrolysis kinetics of lignocellulosic biomass [36], and Varhegyi et al [37] pointed out that the DAEM is the best method available for mathematically representing the physical and chemical heterogeneity of biomass during a devolatilisation process. The application of this model has also been previously studied for polymers with a fast decomposition [36,[38][39][40][41] and blends of coal with petcoke [42], wastes [43] and biomass [44].…”

“…The area-normalized method was used to qualitatively analyze the GC/MS spectrum of pyrolysis products. 32 The effect of the pyrolysis temperature (200°C-900°C), heating rate (10,000°C/s, 1000°C/s, 500°C/s, 100°C/s, 70°C/s, 50°C/s, 30°C/s, 10°C/s, 1°C/s), and residence time(2, 5, 10, 15 s) on the distribution of pyrolysis products of Miscanthus was studied.…”

This work presents a comprehensive study on the effects of pyrolysis parameters (pyrolysis temperature, residence time, and heating rate) on the distribution of pyrolysis products of Miscanthus. Py-GC/MS (Pyrolysis-gas chromatography/mass) was conducted to identify building blocks of value-added chemical from Miscanthus. The results showed that the main pyrolysis products of Miscanthus were ketone, aldehyde, phenol, heterocycles, and aromatic compounds. The representative compounds of ketone and aldehyde compounds produced at different pyrolysis temperatures changed obviously, while the representative compounds of phenolic, heterocyclic, and aromatic compounds had no obvious change. Large-scale pyrolysis of Miscanthus had begun at 400°C, and the relative content of pyrolysis products from Miscanthus reached the maximum of 98.34% at 700°C. The relative peak area ratio of phenol and aromatic compounds reached the maximum and minimum at the residence time of 5 and 10 s, while the relative peak area ratio of ketone compounds showed the opposite trend. The relative peak area ratio of aldehyde compounds was higher under shorter or longer residence time. For heterocyclic compounds, the relative peak area ratio reached the maximum of 27.0% at residence time of 10 s. The faster or slower heating rate was beneficial to the production of aldehyde and phenol compounds. The relative peak area ratio of ketone compounds reached the maximum at 10,000°C/s, 70°C/s, and 10°C/s, and the relative peak area ratio tendency of heterocyclic compounds was similar to ketone. For aromatic compounds, the overall fluctuations were large, and the relative peak area ratio was the highest at the heating rate of 100°C/s.

“…Adding Al2O3 increased the carbon and hydrogen content in the pyrolysis oil, improving the higher heating value (HHV) of the pyrolysis oil [31]. Furthermore, MgO catalysts have been used in the catalytic pyrolysis of MSW, because adding MgO to a pyrolysis reactor improves the deoxygenation rate and the oil quality, as reported by Fang et al [32]. The MSW included food, wood, paper, and plastic [32].…”

Burning municipal solid waste (MSW) increases CO2, CH4, and SO2 emissions, leading to an increase in global warming, encouraging governments and researchers to search for alternatives. The pyrolysis process converts MSW to oil, gas, and char. This study investigated catalytic and noncatalytic pyrolysis of MSW to produce oil using MgO-based catalysts. The reaction temperature, catalyst loading, and catalyst support were evaluated. Magnesium oxide was supported on active carbon (AC) and Al2O3 to assess the role of support in MgO catalyst activity. The liquid yields varied from 30 to 54 wt% based on the experimental conditions. For the noncatalytic pyrolysis experiment, the highest liquid yield was 54 wt% at 500 °C. The results revealed that adding MgO, MgO/Al2O3, and MgO/AC declines the liquid yield and increases the gas yield. The catalysts exhibited significant deoxygenation activity, which enhances the quality of the pyrolysis oil and increases the heating value of the bio-oil. Of the catalysts that had high deoxygenation activity, MgO/AC had the highest relative yield. The loading of MgO/AC varied from 5 to 30 wt% of feed to the pyrolysis reactor. As the catalyst load increases, the liquid yield declines, while the gas and char yields increase. Copyright © 2021 by Authors, Published by BCREC Group.
