“…Pyrolysis is one of the most important and best processes for converting wood and organic compounds into useful products. In the absence of oxygen, using pyrolysis, biomass is converted to vapor and lighter compounds, and some of it remains in the form of char . Generally, in pyrolysis of biomass, many process and structural parameters, such as biomass type, temperature, heating rate, catalyst, carrier gas, particle size, and reactor type, can affect the pyrolysis mechanisms and products.…”

Pyrolysis of Iranian oak has been investigated under different temperatures, heating rates, particle sizes, carrier gases, and zeolite-based catalysts. A semi-batch fixed bed reactor and thermogravimetric analyzer (TGA) were used to carry out the pyrolysis experiments simultaneously. The varied components of the produced organic liquids were measured using gas chromatograph mass spectrometry, and the results showed that phenols, furans, aldehydes, ketones, and hydrocarbons had significant shares of the liquid products. The obtained results from the GC/MS instrument showed that the studied process parameters could affect the type and share of pyrolysis products obviously. Also, the catalysts such as HZSM-5 and Ga/USY, as novel catalysts, had significant impact on the manufactured products, especially hydrocarbons. As a novel method, to make the pyrolysis more effective, the produced liquids were re-pyrolyzed under a pressure of hydrogen and nitrogen (15 bar) with the related catalyst to complete the initial pyrolysis. Also, the pressurized pyrolysis using the HZSM-5 catalyst in the presence of nitrogen was effective in the production of light and aromatic hydrocarbon compounds, while the USY catalyst in the presence of hydrogen had a key role in the production of aliphatics in the gasoline range. Meanwhile, at different heating rates, the nonisothermal mass losses of oak were measured using a TGA instrument. The TGA study showed that the heating rate could affect the degradation trends and that the activation energy decreased moderately with the increase in the heating rate in the studied range (58.80−50.18 kJ mol −1 ).

In this study, waste polyethylene terephthalate (wPET) was converted to liquid fuel by the pyrolysis method. It was also investigated both effects of microwave pre‐treatment and catalyst (sodium borohydride) on total conversion and oil + gas yield. The reaction temperature of 375–425°C and the reaction time of 30 min are sufficient for the pyrolysis of waste plastic samples in a batch reactor. In the pyrolysis of wPETs, the highest oil + gas yield of 45% was obtained under the conditions of reaction temperature of 425°C and reaction time of 30 min. The highest total conversion was 62% of microwave pre‐treated wPETs under catalytic conditions. It can be argued that microwave pre‐treatment and NaBH4 influence the oil + gas yield in pyrolysis experiments. According to the gas chromatography–mass spectrometry (GC–MS) analysis results of the oil products, they consist of aromatic, mono and multi‐ring aromatic compounds and polyaromatic compounds. Higher heating values of the solid products obtained in pyrolysis are approximately 4000–6000 cal/g. According to X‐ray diffraction analysis (XRD) of the solid products, they consist largely of crystalline terephthalic acid (C8H6O4).

Microbial fuel cells—A preferred technology to prevail energy crisis

With ever increasing waste production worldwide, the development of newly emerging technologies is rising and advancing proportionately. Entailed instalment of sophisticated energy-producing plants is constantly expanding to meet the socio-economic demands of communities and industries. Innumerable superior technologies have been introduced to minimise waste pollution while reducing emissions of greenhouse gases hence, combatting the impact of global warming. This review shows energy conversion technologies including gasification, pyrolysis, incineration, landfill, and bioelectrochemical technologies mainly microbial fuel cell (MFC), microbial electrolysis cells (MECs) and microbial electrosynthesis (MES). Traditionally, incineration and landfill are the main mean of waste conversion but not favourable because of their side effects, economic viability, secondary pollution and difficulty in mechanical compression. Recently, biological processes including anaerobic digestion have gained huge interest but possess some inherent drawbacks and cannot provide a comprehensive solution for future waste management. Among energy converting technologies, bio-electrochemical MFC system is highly preferred as an elementary, clean, safe, economically viable and environmentally beneficial technology. MFC a renewable energy technology possesses multidimensional applications of producing electric power and treat wastewater. In addition, the MFCs can be modified into MEC to generate hydrogen energy from various organic matters. Prospective modification recommendations for scale-up application of this technology are also presented.
