An experimental study on co-pyrolysis of municipal solid waste and corn stalk was performed in a fixed-bed reactor under atmospheric pressure. The effect of different blending ratio on the pyrolysis product yields and compositions of the gaseous products was investigated. The results indicated that there exist synergetic effects in the co-pyrolysis of municipal solid waste and corn stalk. Under the different blending ratio conditions, the char and liquid yields were lower than the theoretical values calculated on pyrolysis of each individual municipal solid waste and corn stalk, and consequently the gas yields were higher. H2 and CH4 obtained co-pyrolysis at 800°C-900°C of 40% blending ratio conditions were higher than those of municipal solid waste and corn stalk alone.

To investigate the effects of gangue on pyrolysis of municipal solid waste (MSW), pyrolysis of MSW with gangue has been conducted by TG and fixed-bed reactor, respectively. The effect of gangue on pyrolysis product yields and compositions of gaseous products was investigated and the obtained results were compared with similar experiments without gangue. It was shown that gangue can improve the pyrolytic reaction of MSW, reduce the char yield, increase the liquid yield. And influences of gangue on yields of H2, CO, CH4 and CO2 were more apparent, the yields of H2, CO and CO2 with gangue were improved 12.5%, 11.8% and 175%, respectively, conversely, the yield of CH4 was reduced 15.4% compared with no gangue.

Purpose The purpose of this paper is to investigate fast pyrolysis of maple fruit as an energy sources. This could serve as a solution to the energy sources problem. Design/methodology/approach Fast pyrolysis of maple fruit (samara) was achieved in a fixed bed reactor. The pyrolysis experiments have been conducted on the sample of maple seeds to particularly determine the effects of pyrolysis temperature, particle size and sweep gas flow rate on the pyrolysis product yields. Findings The oil of maple fruit from fast pyrolysis has good properties to be a potential candidate as a biofuel or as a source of chemicals. In addition to being environmentally desirable, it can reduce the energy cost, e.g. that Turkey imports a majority of its energy. Originality/value The use of maple fruit for fast pyrolysis and pyrolysis conditions impact on the yields of pyrolysis liquid can be considered as novel aspects of this paper.

Surrogate municipal solid waste (MSW) has been prepared to represent high plastic content waste with low fixed carbon in order to be utilized for feedstock for the gasification and pyrolysis. The major components are plastic (PE and PP), food and kitchen waste, and paper, whereas the minor components are textile, rubber, and biomass. Reactions were conducted in small drop tube fixed bed reactor with isothermal reaction temperature at 700, 800, and 900 °C. Steam was supplied as the gasifying agent for the main purpose of producing hydrogen-rich gas. Pyrolysis was also conducted at the same condition to observe the characteristic differences. Producer gas, including H2, CH4, and CO, of both the reactions was a function of the temperature, whereas CO2 showed a reversed trend when the reaction temperature was increased. Simple kinetic models of those gaseous formations were studied for describing the related parameters. It is challenging to determine the kinetics of the individual gas generation while most kinetic studies have focused on mass deterioration. The commonly used kinetic model of nucleation of Avrami–Erofe'ev (A2) could well predict the mechanism of the gas formation of gasification. In parallel, the pyrolysis conformed to the A3 model due to the slower rate of char and tar decomposition when the gasifying agent was absent. The activation energy of each gaseous species and the fitting of experimental data with the selected models are examined in this study.
