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...

Modeling is regarded as a suitable tool to improve biomass pyrolysis in terms of efficiency, product yield, and controllability. However, it crucial develop advanced models estimate products' yield composition functions type/characteristics process conditions. Despite many developed models, most them suffer from insufficient validation due the complexity determining chemical compounds their qua...

Activated charcoal can be obtained in many ways. The most promising terms of resource saving and economic benefits is the method obtaining activated carbon from organic waste by slow conductive pyrolysis. As a result such thermochemical conversion, biochar volatile products - condensable non-condensable are formed, which used as fuel for operation pyrolysis reactors. Modeling thermal decomposit...

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...

In this study, the pyrolysis of sugarcane bagasse in a CO2 atmosphere under conventional and microwave-assisted heating is investigated to achieve CO2 utilizat...

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...

A detailed biomass pyrolysis kinetic scheme was assessed in the multiscale simulations of a single-particle pyrolyzer with slow and pilot-scale entrained flow fast pyrolysis. The developed by CRECK group consists 32 reactions 58 species. simulation model developed, where kinetics employed to simulate reactions, one-dimensional particle utilized intraparticle transport phenomena, particle-in-cel...

A thermogravimetric analyzer was used to conduct a kinetic investigation of rice husk pyrolysis. The major goal is investigate the reaction kinetics at various heating rates in an inert 99.5 percent nitrogen atmosphere. Kinetics’ importance can be explained by fact that it provides evidence for chemical process mechanisms. Understanding mechanisms help you figure out best way get happen. Furthe...
