It is critical for the sustainable development of China to use geothermal energy as a renewable resource, as China is the largest country in energy consumption and the second largest economy in the world [19, 20].To ensure China's security in the field of energy and environment, the Chinese government proposed to improve the level of …
This chapter addresses key issues associated with the utilization of coal in the United States.As noted in Chapter 1, although the committee's task is broad and encompasses the entire coal fuel cycle, the congressional framers of this study requested that it focus primarily on the "upstream" aspects of the coal fuel cycle, recognizing that the research …
As the focus of coal mining in China shifts to the northwest (Fan et al., 2020; Wang et al., 2018a, 2018b, 2018c), Xinjiang has become an important force in China's coal production and supply chain (Yu et al., 2021).Xinjiang has 138 different types of identified mineral resources and 1803,773 million tons of coal reserves (Li et al., 2019).Due to the …
As a consequence, deep exploration and development, as well as the clean and efficient utilization of coal and coal-related resources (e.g., toxic elements in coal, strategic …

Coal is a major source of energy in China. Quantifying China's coal supply sustainability is essential to track China's efforts towards sustainable development and achieve carbon neutrality goals. In this research, in addition to availability, economic sustainability, environmental sustainability and technological sustainability, we specially …
The advancement of green coal conversion technologies is of great importance to global sustainable development. Two novel coal utilization methods are introduced in the current dissertation, underground coal thermal treatment (UCTT) and photoelectrochemical (PEC) coal gasification. UCTT is a proposed method for producing light hydrocarbon …
On the other hand, high quality coals such as good quality bituminous coals are required for producing metallurgical coke. Fig. 1 shows the coal band and the expansion target of coal resources for ...
Knowing the physical properties of coal is important in the preparation and use of coal. For example, coal density ranges from about 1.1 to about 1.5 megagrams per cubic metre, or grams per cubic centimeter. Coal is slightly denser than water and significantly less dense than most rocks and mineral matter.
Coal utilization and coal downstream development12.7.1. Clean coal technology. The Ministry of Energy and Mineral Resources (ESDM) released a National Coal Policy in January 2004. The aim of the policy is to provide guidance in the management, exploitation, utilization and development of coal from 2005 to 2020.

Abstract. Geothermal energy has been used for centuries for bathing, cooking and space heating. More recently district heating and industrial processing along with geothermal heat pumps has become part of the direct-use mix. Geothermal electric power generation was started in Italy in 1904, with the first commercial plant on line in 1913.
1. Introduction. Traditional coal chemical production is characterized by low energy efficiency and high CO 2 emission. The hydrogen-to-carbon (H/C) ratio of coal is about 4:5, while those of methanol, olefins, liquid fuels, and natural gas, which are chemical products of coal, are about 2:1, 2:1, 2:1, and 3:1, respectively [1, 2].The mismatch …
