Three representative forms of coal consumption subsidization are identified and measured in this paper: feed coal supply at a preferential price, prior access to coal mining rights, and privilege in coalmine M&A (mergers and acquisitions) cases. Using China's coal-to-liquids (CTL) industry as a case study, we find that the current subsidy helps ...

Synthetic fuel production by indirect coal liquefaction Article in Energy for Sustainable Development 7(4) · December 2003 with 156 Reads How we measure 'reads'

In the People's Republic of China, there is a tremendous amount of accessible coal, but very little availability of other fuel sources such as oil, gas, and kerosene. However, through a thermal chemical process, coal can be liquefied. Once it is in a liquid state, it .

Coal liquefaction is a process of converting coal into liquid hydrocarbons: liquid fuels and petrochemicals.This process is often known as "Coal to X", where X can be many different hydrocarbon-based products. However, the most common process chain is "Coal to Liquid Fuels" (CTL).

The Need for Reaction Engineering in Coal Liquefaction Commercial coal liquefaction plants represent huge investments in capital. For example, the Breckenridge H-Coal plant was sized to produce 80,000 BSD of liquid products and cost estimates were in excess of 2.5 billion dollars in the mid 80's. Small errors in equipment sizing or yield ...

Companies that sell natural gas mainly use LNG liquefaction units to liquefy and transport natural gas. The largest producer of LNG is Qatar, whose liquefaction capacity is roughly one-quarter of global LNG liquefaction capacity as of late 2013 (source: International Energy Agency). Natural gas is a cleaner burning fuel than coal, for example.

Why Coal Liquefaction? Alternate source for liquid fuels: national energy security ♦Germany, Japan, South Africa Production of a clean and reactive solid fuel: SRC ♦Liquids are a secondary product that may improve economics Oil embargos in the 1970's reinforced need for an alternate source of transportation fuel

Reason for Discussion of Direct Liquefaction of Coal in Gasifipedia As the following discussion of Direct Coal Liquefaction (DCL) explains, the fundamental process approach of DCL does not involve gasification at all. Therefore it would seem to be entirely out of scope of Gasifipedia. However, the following considerations require that discussion of DCL be included:

Coal preparation, or beneficiation, is a series of operations that remove mineral matter (i.e., ash) from coal.Preparation relies on different mechanical operations (not discussed in detail here) to perform the separation, such as size reduction, size classification, cleaning, dewatering and drying, waste disposal, and pollution control.

Jun 29, 1999· A coal agglomerate is produced by the combination of coal fines with a binder obtained by the direct liquefaction of biomass material. The direct liquefaction is carried out in the absence of oxygen at typical temperatures between about 450 and 700° F. and typical pressures between 200 and 3,000 psi, according to known liquefaction processes.
