“…This process could achieve a cyanide decomposition rate of 99.12% and a fluoride leaching rate of 96.63%. Zhang et al (2021) proposed a method of mixing SCCs in burning lean coal to utilize SCCs. Below 1000 C, the release of hydrogen fluoride (HF) was relatively low, with a combustion activation energy of 59.87 kJ·mol −1 at a blending ratio of 5%.…”

Aluminium is produced by electrolysis using alumina (Al2O3) as raw material and cryolite (Na3AlF6) as electrolyte. In this Hall–Héroult process, the energy consumption is relatively large, and solid wastes such as spent anodes and spent pot liner, flue gas and waste heat are generated. Therefore, this article discusses from the perspective of high energy consumption and high pollution and summarizes the methods to reduce energy consumption and solve pollution problems. The functions of carbon anode, carbon cathode, refractory material and sidewall in aluminium electrolysis cells are discussed in detail. The process of aluminium electrolysis and the ways to improve the current efficiency of aluminium electrolysis cells and reduce their energy consumption are outlined. The causes and treatment methods of spent anodes, spent cathodes, spent refractories and spent spot liner are reviewed. The research progress of waste heat recovery and aluminium electrolysis flue gas purification are analysed. And the future research directions of aluminium electrolysis flue gas are provided.

“…The cyanides were effectively decomposed at high temperatures and Ar–O 2 atmosphere, with around three-quarters of the cyanides being converted to the N 2 and nearly a quarter being to the NO. Finally, analysis of the flue gas composition indicated that it had a more complicated composition [ 273 , 274 ].…”

On-Line Thermally Induced Evolved Gas Analysis: An Update—Part 1: EGA-MS

et al. 2022

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.
