Aug 14, 2013· Currently there are two proven ways to convert coal into clean fuels. One is the Direct coal liquefaction process, which converts coal to liquids by dissolving coal in a solvent at high temperature and pressure. This process is highly efficient, but the liquid products require further refining ('hydrocracking' or adding hydrogen over a ...

Erdos CTL (sometimes also referred as Shenhua CTL) is a coal liquefaction plant at Ejin Horo Banner in Inner Mongolia, China.It is the biggest coal-to-liquids complex outside South Africa with a capacity of 20,000 barrels per day (3,200 m 3 /d).. The plant is owned by Shenhua Coal Liquefaction, a subsidiary of Shenhua Group.It uses direct coal liquefaction technology developed by Shenhua Group.
Direct Coal Liquefaction The process of direct coal liquefaction was developed in the 1920's in Germany. Until the mid 1950's the process was operated at several sites in Germany to derive liquid hydrocarbons from coal as a substitute to standard crude oils. In the 80's and 90's the Kohleoel-Anlage in Bottrop plant was

First CTL commercial plant in China. The Shenhua Group Corporation, which is one of the world's largest coal companies, began to construct the world's first commercial direct coal liquefaction plant, located in Inner Mongolia (80 miles south of Baotau at Majata) in 2003, at a cost of $3.2bn (this is an area with huge coal fields).
A number of companies are looking at is the use of small-scale LNG to meet small generation needs, such as island grids and distributed generation.

A direct coal liquefaction method and apparatus in which the feed coal is mixed with a recycled 600° F+ non-donor stream in which the ratio of coal to said stream is at least 1.5:1 on a moisture free basis to form an input slurry to a DCL reactor. Hydrogen containing treat gas is supplied to the reactor. 1000° F- bottoms from the reactor are recycled as part of the 600° F+ non-donor stream ...
Coal Liquefaction is the process of converting coal to liquid fuels. Coal Liquefaction Definition. The process of coal liquefaction creates synthetic liquid fuels from solid coal as substitutes for various petroleum products. There are two types of liquefaction - direct and indirect Williams R.

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:
liquefaction of Illinois No. 6 bituminous coal concluded that commercial CTL plants using the US Midwestern bituminous coal offer good economic opportunities. The investment cost of a CTL plant with a production capacity of 50,000 bbl/d of diesel and gasoline is around $ 4.1 billion (US$ 2006).
Keywords: Direct coal liquefaction, indirect coal liquefaction, EDS process, H-coal process 2.5 Coal liquefaction Coal liquefaction is a process where coal is converted into liquid fuels, mainly to provide substitutes for petroleum products, which may be either used directly as fuel or converted into chemicals or other liquid fuels.
Coal liquefaction is a process that has been around for a long time. Although relatively unfamiliar in the American energy vocabulary, it dates back to 1923 when German scientists developed the Fisher-Tropsch process for converting coal into the liquid fuels of gasoline and diesel.
Risk associated with soil and water contamination in the process of coal liquefaction is high. High capital investment in setting up liquefaction plants and technology implementation are also hampering the coal liquefaction market. In terms of region, owing to technological advancements and geological characteristics of North America, surplus ...
