Application of the Chemical-Looping Concept for Azoetrope Separation
The need for the separation of azeotropic mixtures for the production of high-end chemicals and resource recovery has spurred significant research into the development of new separation methods in the chemical industry. In this paper, a green and sustainable method for azeotrope separation is proposed based on a chemical-looping concept with the help of reversible-reaction-assisted distillation. The central concept in the chemical-looping separation (CLS) method is the selection of a reactant that can react with the azeotrope components and can also be recycled by the reverse reaction to close the loop and achieve cyclic azeotrope separation. This paper aims to provide an informative perspective on the fundamental theory and applications of the CLS method based on the separation principle, reactant selection, and case analysis, for example, the separation of alkenes, alkane, aromatics, and polyol products. In summary, we provide guidance and references for chemical separation process intensification in product refining and separation from azeotropic systems for the development of a more sustainable chemical industry.

Recently, urbanization, economic development, and industrial structure adjustment are decreasing the number of permanent residents in rural areas in China on a yearly basis; the rural population is aging and the natural villages are gradually declining or even dying out. Considering the overall situation of rural natural villages in China, we selected a typical village in Shandong province as the object for field research. This study analyzes the idle situation of rural houses and the population distribution in the rural areas and summarizes the specific characteristics that indicate the decline of natural villages. Subsequently, it also analyzes the underlying reasons for the decline using the dissipative structure theory, and proposes that a new dissipative structure should be established by opening and activating conventional villages, protecting featured villages, and integrating declined villages. Furthermore, the internal management of the updated villages should be improved to increase the cohesion and self-organizing ability of the new system.

Strategic Path for Energy Revolution in Northwest China in the New Era
Both energy security and climate change are key challenges for China in the New Era. Northwest China, especially the Energy Golden Triangle area and Xinjiang, is playing a significant role in China’s energy supply owing to its rich energy resources. However, protecting the vulnerable ecosystems in this region becomes increasingly challenging; therefore, developing a performance improvement plan for energy revolution becomes urgent in this region. In this article, we first analyze the unique competencies and challenges regarding resource, industry, and location; considering the requirements of energy revolution, we propose that the Northwest China should be established as a national multi-energy integration technology demonstration base, a national coal-to-fuel strategic reserve base, and a national comprehensive energy supply base. As a strategic path for promoting energy revolution in Northwest China, multi-energy integration consists of three main themes and six demonstration measures. The three main themes are the clean and efficient use of fossil resources and coupling substitution, multi-energy complementarity and large-scale application of renewable energy, and the low-carbon and intelligent multi-energy integration. Adopting these measures, a Northwest China approach to energy revolution can be formed that is characterized by multi-power integration and led by energy technology revolution.

Based on the strategic background, positioning, and objectives of the planning and construction of the Xiongan New Area, an analysis model framework is established for the requirements for energy revolution during the planning and construction of this area. We conclude that energy revolution can actively promote the construction of the Xiongan New Area. Specifically, energy technology revolution can aid the Xiongan New Area to become a global energy innovation center; the energy operation mode of this area can be reformed through energy system revolution; the planning and construction requirements of the Xiongan New Area can be satisfied through energy consumption revolution; and a safe and efficient energy supply system can be ensured through energy supply revolution. Furthermore, an urban energy supply system that is green, safe, efficient, smart-friendly, and future-leading can be created in the Xiongan New Area through the energy revolution, particularly through key projects regarding energy integrated operation systems, energy Internet, green and smart transportation systems, ultra-low-energy buildings, and energy saving and emission reduction.

Thoughts and Countermeasures on Promoting Energy Revolution in the Beijing–Tianjin–Hebei Region
Beijing–Tianjin–Hebei coordinated development is a major national strategy of China. This study first analyzes the evolution process of energy production, consumption, and structure proportion in Beijing, Tianjin, and Hebei, indicating that the overall energy supply in this region is less than consumption; although the region is rich in renewable energy resources, its energy consumption is mainly fossil energies and the overall energy efficiency requires further improvement. Since the Beijing–Tianjin–Hebei coordinated development strategy was proposed six years ago, the ecological environment in this region has continuously improved, but the situation remains grim. As energy is the power source and blood of economic and social development and it is also closely related to the environment, the promotion of energy revolution becomes imperative. To promote energy revolution within the Beijing–Tianjin–Hebei region, energy efficiency should be further improved to control the total amount of energy consumption; the energy supply structure should be optimized to provide a solid material foundation for the coordinated development; the energy technology revolution should be promoted to create a new driving force for economic growth; the existing energy system should be revolutionized to improve the market environment for economic and social development; and the rural energy revolution should be accelerated to strengthen the prevention of point source pollution in rural areas.
