Approaches for controlling air pollutants and their environmental impacts generated from coal-based electricity generation in China

Abstract

This study aims at qualifying air pollutants and environmental impacts generated from coal-based power plants and providing useful information for decision makers on the management of coal-based power plants in China. Results showed that approximately 9.03, 54.95, 62.08, and 12.12% of the national carbon dioxide, sulfur dioxide, nitrogen oxides, and particulate matter emissions, respectively, in 2011were generated from coal-based electricity generation. The air pollutants were mainly generated from east China because of the well-developed economy and energy-intensive industries in the region. Coal-washing technology can simply and significantly reduce the environmental burden because of the relativity low content of coal gangue and sulfur in washed coal. Optimizing the efficiency of raw materials and energy consumption is additional key factor to reduce the potential environmental impacts. In addition, improving the efficiency of air pollutants (e.g., dust, mercury, sulfur dioxide, nitrogen oxides) control system and implementing the strict requirements on air pollutants for power plants are important ways for reducing the potential environmental impacts of coal-based electricity generation in China.

Do Higher Education Research and Development Expenditures affect Environmental Sustainability? New Evidence from Thirty-One Chinese Provinces

“…As some tech companies have started using solar and wind for power generation, other sectors will also follow this campaign to reduce their carbon footprint. This result validates the previous studies conducted for China (Akadiri et al, 2020;Munir & Riaz, 2020;Xu et al, 2015;Zhang, 2019); Spain (Zarco-Soto et al, 2020); South Asian economies (Munir & Riaz, 2019); Bangladesh (Shahbaz et al, 2014); ASEAN countries (Lean & Smyth, 2010); Pakistan (Rehman et al, 2019) and BRICS (Haseeb et al, 2019).…”

“…Yorucu and Varoglu (2020) studied the nexus among industrial production, electricity consumption, economic growth, and CO 2 e in selected small island states. Based on the FMOLS and DOLS estimations, the authors found that a one percent increase in electricity consumption predicted an upsurge of 0.79 percent in CO 2 e. In the same way, others studies have also reported a positive connection between electricity consumption and CO 2 e for China (Akadiri et al, 2020;Munir & Riaz, 2020;Ou, Xiaoyu, & Zhang, 2011;Xu, Hong, Ren, Wang, & Yuan, 2015;Zhang, 2019); Spain (Zarco-Soto, Zarco-Periñán, & Sánchez-Durán, 2020); South Asian economies (Munir & Riaz, 2019); Bangladesh (Shahbaz, Salah Uddin, Ur Rehman, & Imran, 2014); ASEAN countries (Lean & Smyth, 2010); Pakistan (Rehman et al, 2019) BRICS (Cowan, Chang, Inglesi-Lotz, & Gupta, 2014;Haseeb, Xia, Saud, Ahmad, & Khurshid, 2019); and Kuwait (Salahuddin, Alam, Ozturk, & Sohag, 2018).…”

Ultrasonication-Assisted Preparation of a Mn-Based Blast Furnace Slag Catalyst: Effects on the Low-Temperature Selective Catalytic Reduction Denitration Process

“…Most of the NO x are mainly produced by human activities, including stationary source (coal) combustion 8 , 9 and mobile source (motor vehicle) combustion. 10 In recent years, due to the popularization of high-efficiency three-way catalysts and denitration devices in coal-fired power plants, NO x has been controlled to a certain extent. 11 However, in industries such as steel, coking, cement, glass, and ceramics, 12 − 16 NO x pollution is still serious.…”
