“…The temperature inside a fixed bed reactor was varied in the range of 600-800 • C. It was established [78] that the layer temperature increase led to a higher production of pyrolysis gas in general, and H 2 in particular. A similar conclusion was made by Li et al [79]. When the temperature of microwave pyrolysis of straw was varied from 500 to 900 • C, the volume of the gaseous pyrolysis product increased by 33%.…”

The development of the world economy goes hand in hand with increased energy consumption and global warming caused by greenhouse gases. These issues can be tackled by implementing promising technologies of power generation. They differ from the known ones in that new energy resources are involved, e.g., mixtures of various types of biomass, provided that hazardous gas emissions during the production process are minimized. The development of high-potential energy-efficient and environmentally friendly technologies which use biofuel in the energy industry requires scientific evidence for the mechanisms, conditions, and characteristics of physical and chemical processes during pyrolysis and gasification of biomass, including its multicomponent types. This article analyzes the world technologies and research findings in the field of biomass pyrolysis and gasification. The effect of a group of factors on the intensity and completeness of gasification and pyrolysis of biofuel compositions has been determined. These factors include the size, shape, and surface structure of biomass particles; component composition and properties of fuel mixtures; mechanism and intensity of heat supply; and the temperature field in the reactor filled with solid and gaseous products. The most effective values of these characteristics have been established.

“…When contrasted with traditional heat operations, the microwave may produce much more gas and help generate less tar. [109] To increase the efficiency of TCMR pyrolysis, reactor linkage technology, and feedstock co-pyrolysis have been extensively applied. [110][111][112][113][114] Indeed, some academics have proposed combining a transport fluidized bed with a fluidized bed for gasifying TCMR.…”

Chinese medicine is widely employed in illness prevention and treatment. In recent years, the increased demand for Chinese medicine resources has resulted in a large quantity of waste created during industrialization. However, traditional methods for treating herbal residues, including burning, stacking, and burying, can cause significant environmental damage and resource waste. Furthermore, these application approaches have a low level of resource utilization and a low degree of utilization. Therefore, developing a classification management system is a necessary precondition for reusing Chinese herb residues for medicinal, feed, fertilizer, and energy resource reuse. This paper reviews the potential applications of Chinese herb residues in the extraction of active resources, composting, feed addition, bioethanol preparation, and pyrolysis to biochar, bio‐oil, and fuel gas. Overall, this work provides a foundation for further investigation into the high‐value usage model and resource reuse pathway of Chinese herb residues.

“…Microwave pyrolysis for integrated with in situ reforming was proposed for clean syngas production from herb residues, a typical industrial biomass waste that has high moisture and nitrogen content. Effects of microwave heating, reaction temperature, and types of catalysts were investigated, and the tar elimination and nitrous oxides controlling performance were evaluated [ 250 ].…”

Advances in on-line thermally induced evolved gas analysis (OLTI-EGA) have been systematically reported by our group to update their applications in several different fields and to provide useful starting references. The importance of an accurate interpretation of the thermally-induced reaction mechanism which involves the formation of gaseous species is necessary to obtain the characterization of the evolved products. In this review, applications of Evolved Gas Analysis (EGA) performed by on-line coupling heating devices to mass spectrometry (EGA-MS), are reported. Reported references clearly demonstrate that the characterization of the nature of volatile products released by a substance subjected to a controlled temperature program allows us to prove a supposed reaction or composition, either under isothermal or under heating conditions. Selected 2019, 2020, and 2021 references are collected and briefly described in this review.
