      Burning coal emits large amounts of carbon dioxide into the atmosphere. Coal is composed almost entirely of carbon, so burning coal unleashes large amounts of carbon dioxide (CO 2) into the atmosphere. These emissions have been shown to increase the greenhouse effect in the atmosphere and lead to global warming. Subsurface coal mining is :// /what-is-the-environmental-impact-of-mining-and-burning-coal. Coal has been mined and used as a source of energy for centuries. The first recorded use of coal was in China, with indications that the Chinese began using coal for heating and smelting about years ago, and most historians believe that coal was used in various parts of the world – years ago during the Bronze Age [].A system for mining coal was present in England by [].

of The direct liquefaction process (Fig. 3) employs a coal ground to a fine powder, solvent, hydrogen, and catalyst employed at elevated pressures (– psig) and temperatures (–°C).The solvent mixed with the coal forms a pumpable paste.

Intimate contact between solid coal and solvent is easier to achieve than that between coal and gaseous hydrogen; therefore, in addition to   Both conventional coal technology and the newer coal-conversion processes have a considerable potential for environmental and health-related impacts.

This chapter discusses a number of precise and sensitive techniques for both sampling and analysis of coal-conversion plant feedstocks, effluents, products, and by-products for these elements   This chapter reviews the potential health problems that the adoption of coal conversion technologies may engender.

In spite of the limited experience and information available in this field, it is prudent to explore this topic to gain insights into the factors that need to be monitored, the control technologies that may require incorporation into plant design, and the environmental standards Factors related to an even distribution and good mixing may limit practical diameter Environmental factors in coal liquefaction plant design book in scale-up of the reaction vessel to commercial size.

The system converts about 90 percent of the carbon con- tained in coal to a liquid.

The NG liquefaction process is the heart of the LNG value chain however it suffers from being a very energy intensive process.

Lim et al. () reviewed the current NG liquefaction technologies and optimization studies for performance improvement. The efficient design and operation of liquefaction plants   As the cost of production is a key determinant of long-term viability, developing methods that reduce the cost of direct coal liquefaction has posed a challenge to scientists and industrial organizations worldwide.

This paper summarizes recent developments in technology and processes and explores the overall economic competitiveness of direct coal liquefaction using the China Shenhua Group Technical Report: Assessment of materials selection and performance for direct-coal- liquefaction plants in the United States An industrial coal blend was carbonized at the ENSIDESA industrial coking plants at and °C (T1 and T2) and at the INCAR coking test plant atand °C (T3, T4 and T5), respectively.

The same coal blend was also preheated at °C and then carbonized at °C (T6). Liquefaction process is one of the well-known oldest methods among the thermochemical biomass conversion routes and there is an increasing interest in biomass :// The growing demand for petroleum, accompanied by the declining petroleum reserves and the concerns over energy security, has intensified the interest in direct coal liquefaction (DCL), particularly in countries such as China which is rich in coal resources, but short of petroleum.

In addition to a general introduction on the mechanisms and processes of DCL, this paper overviews some recent Process selection and recent design innovations for LNG plants—Part 2. Al-Mutaz, I. Wazeer and R. Khan, King Saud University, Riyadh, Saudi Arabia; and A.

Stasisław; Conversion. In general, coal can be considered a hydrogen-deficient hydrocarbon with a hydrogen-to-carbon ratio nearas compared with a liquid hydrocarbons ratio near 2 (for propane, ethane, butane, and other forms of natural gas) and a gaseous hydrocarbons ratio near 4 (for gasoline).

The United States Department of Energy’s Office of Fossil Energy, through the Gasification Systems Program, is developing flexible, innovative, resilient, and transformative modular designs for converting diverse types of US domestic coal and coal blends with biomass, municipal solid waste (MSW), and waste plastics into clean synthesis gas to enable the low-cost production of electricity Robinson and Tatterson [4] est imated an indirect coal liquefaction plant producing 9, barrels per day of diesel would cost $ b illion or $,/daily barrel.

LNG exhibits comparative economic advantages to pipeline supplies of natural gas over long distances and comparative environmental advantages relative to competing powerThe outlook for coal use in the United States is governed by two major factors, namely, the desirability of using an abundant, low-cost, and secure domestic energy resource and the need to comply with increasingly stringent environmental control ://In the Shenhua DCL project, middle coal, oil residue, and tail gas that are produced in coal liquefaction are burned in the combustor of a captive power plant to create electricity that meets on
