Fast pyrolysis is an efficient technique for thermal degradation of lignin to bio-oils containing bio-phenols for the synthesis of adhesives, resins, and polymers. Lignin has a complex structure, and hence a large number of pyrolytic components are generated during the pyrolysis process. The composition of the pyrolytic products depends on the type of lignin, temperature, types of catalyst, and...

Co-pyrolysis of Shenmu coal (SM) and cotton stalk (CS) at different blend ratios were carried out in a tubular furnace. The pyrolysis temperature was up to 600 °C at 5 °C/min and kept for 15 min. The results indicated that there was an interactive effect between SM and CS, which increased the tar yield. Moreover, the content of light components in co-pyrolysis tar from all CS/SM blend ratios wa...

*Correspondence: Wei-Hsin Chen, Department of Aeronautics and Astronautics, National Cheng Kung University, Tainan 701, Taiwan e-mail: [email protected] Pyrolysis is an important thermochemical method to convert biomass into bio-oil. In this study, the pyrolysis of sugarcane bagasse in a CO2 atmosphere under conventional and microwave-assisted heating is investigated to achieve CO2 utilizat...

Pyrolysis is an applicable method that has been widely used to recover hydrocarbons from Used Lubricating Oil (ULO). However, large-scale application of this approach has been limited by its noticeably energy and time consuming nature. In the present research, it has been attempted to modify the energy and time requirements of ULO pyrolysis using the catalytic effects of metal oxide nanoparticl...

In this study, sewage sludge and mycelial waste from antibiotic production were pyrolyzed in a batch scale fixed-bed reactor as examples of two kinds of typical industrial biomass wastes with high nitrogen content. A series of experiments were conducted on the rapid pyrolysis and the slow pyrolysis of these wastes in the temperature range from 500–800 °C to investigate the Fuel-N transformation...

This study was aimed to investigate the effect of mineral matter of Göynük oil shales (GOS) on pyrolysis and product evolution. Organic part was separated from mineral matter before pyrolysis in an isothermal pyrolysis reactor. In the demineralization step, carbonate, pyrite and silicates were removed from kerogen by using HCl, HNO3 and HF, respectively. Thereafter all samples were pyrolized in...

This work aimed to investigate the impact of highest treatment temperature (HTT), heating rate, carrier gas flow rate and feedstock on the composition and energy content of pyrolysis gas to assess whether a self-sustained system could be achieved through the combustion of the gas fraction alone, leaving other co-products available for alternative high-value uses. Calculations based on gas compo...

Studies on the pyrolysis of the synthetic cannabinoid agonist UR-144 ((1-pentyl-1H-indol-3-yl)(2,2,3,3-tetramethylcyclopropyl)methanone) have shown that its major pyrolysis product is a tetramethylcyclopropane ring-opened alkene. Considering that smoking is a common way of ingesting synthetic cannabimimetics, the presence of the metabolites of this pyrolysis product would be expected in biologi...

This paper presents an extensive review of the scientific literature associated with various microwave pyrolysis applications in waste to energy engineering. It was established that microwave-heated pyrolysis processes offer a number of advantages over other processes that use traditional thermal heat sources. In particular, microwave-heated processes show a distinct advantage in providing rapi...

AIEWRACT-The pyrolysis of general biomass materials is modeled via a superposition of cellulose, hcmiccllulosc and lignin kinetics. All three of the primary biomass components arc modeled with multi-slcp kinetics involving both compcte-tivc primary pyrolysis and secondary tar decomposition reactions. Only " typical " (untreated) fccdstocks arc considered at at mosphcric pyrolysis pressures. The...
