“…They then investigated the catalytic oxidation of toluene using NTP synergistic MCD x . [81] In comparison to a solitary NTP, the addition of MCD x drastically reduced the emission concentration of the by-product O 3 and significantly improved the toluene catalytic efficiency, energy efficiency, and 2 selectivity. The MCD 6 has the best toluene catalytic efficiency (95.2 %) and CO 2 selectivity (81 %) at a power of 17 W. This is explained by the superior toluene adsorption capabilities of MOFs, which can trap toluene in their porous structures, extending toluene's residence time in the reaction system and raising the likelihood of intermolecular collisions, which boosts the rate of degradation.…”

Volatile organic compounds (VOCs) emissions are a factor in a number of environmental issues. To reduce the associated negative consequences, it is crucial to develop efficient VOCs removal systems. Non‐thermal plasma (NTP) co‐catalytic technology has become a popular research topic in this field as a result of its ability to reduce the activation energy of the reaction while simultaneously improving product selectivity. Despite the huge number of studies synthesising the use of metals and their oxide catalysts in the degradation of VOCs, metal‐organic frameworks (MOFs) and MOF derivatives are the subject of comparatively few studies in this area. This paper reviews the basic principles and technological progress of NTP co‐catalytic VOCs degradation, with a focus on the use of MOFs and their derivatives in plasma VOCs degradation, as well as the use of other non‐metallic carbon materials in plasma VOCs degradation. It highlights the potential future development direction of NTP catalytic synergistic treatment of VOCs by focusing on the optimization of catalytic synergism on the treatment impact. In the end, the challenges faced, the prospects, and our personal perspective on future research directions are also estimated and elucidated.

The high-pressure feedwater (HPFW) heater is one of the main auxiliary equipment in thermal power plants, and the configuration of the bypass for the HPFW heater has a significant impact on the safety and economy of the power generation unit. In this study, with a focus on an ultra-supercritical double reheat unit with parameters of 35.5MPa/616℃/631℃/631℃ and a back pressure extraction steam turbine (BEST) cycle reheating system, various aspects of the HPFW heater bypass, including the bypass configuration, bypass operation mode, heater removal conditions, and economic comparison, were analyzed based on the variable operating conditions theory. After the cutoff of the HPFW heaters, there was a noticeable increase in the heat consumption of the unit, leading to a rise in coal consumption for power generation. In the case of a complete cutoff of the HPFW heaters, the unit load needed to be restricted to 40% or lower to ensure the safe and stable operation of the unit. For the three-three grouping cutoff scheme of the HPFW heaters, the unit load must be restricted to 75% or lower for stable operation. The two-two grouping cutoff scheme for the HPFW heaters could guarantee the safe and stable operation of the heater cutoff conditions while maintaining full load operation. The BEST cycle reheating system was characterized by its complex configuration and numerous equipment. The start-up, operation adjustment, and control of HPFW heater cutoff conditions, as well as the operation under special conditions, involve a multivariable coordinated control process.

“…Common recovery techniques include adsorption, absorption, condensation, and membrane separation. Decomposition techniques, on the other hand, chemically destroy the molecular structure of VOCs through combustion, catalysis, oxidation, and other methods to eliminate the impact of VOCs [6]. Major decomposition techniques include combustion, photocatalysis, plasma treatment, catalytic oxidation, thermal catalysis, and biodegradation [7].…”

Volatile Organic Compounds (VOCs) are significant contributors to air pollution and play a crucial role as precursors for secondary pollutants such as O3, thereby posing severe health risks and attracting global attention. ZIF-67, a metal-organic framework (MOFs), possesses a porous microstructure and high specific surface area, offering exceptional adsorption performance, catalytic activity, and structural stability. In this investigation, a solvent-thermal method was employed to synthesize a series of Fe-modified ZIF-67 denoted as FCMx. The impact of Fe doping and temperature on the dynamic adsorption performance of toluene was examined. The results revealed satisfactory adsorption performance of FCMx when the Fe doping was 14 mol%. FCM14 achieved saturation adsorption of toluene in approximately 5000 s, exhibiting a saturated adsorption capacity of 1769.80 mg/g at 25 °C. This represented a 25% improvement in adsorption time and a 30% increase in saturated adsorption capacity compared to undoped ZIF-67. Furthermore, at a reaction temperature of 150 °C, FCM14 exhibited saturation time of approximately 4300 s and a saturated adsorption amount of 1471.43 mg/g, indicating a combined effect of chemical and physical adsorption. The findings of this research provide valuable experimental data and theoretical support for the potential industrial application of MOFs in VOC adsorption.
