The US Department of Energy DOE had a very active coal liquefaction research program in 1970 into the 1980s in response to the Organization of the Petroleum Exporting Countries OPEC oil embargo of 1973 but the funding has been greatly reduced since the 1990s when the DOE development for direct coal liquefaction ended... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
Coal briquetting machine is also called coal briquette press machine, which can press powdered or granular coal slime, raw coal and lignite coal into spherical shape, oval shape and flat shape with strong pressure.
Coal mill is a kind of ball mill, which is often used to crush and grind coal bricks into powder, so it is also called coal grinding mill. Coal mill is the main equipment in cement plant, which is used for drying and grinding of coal.
Coal dryer is available for drying all kinds of coal, such as anthracite, lean coal, Mongolian coal, clean coal, nickel coal, coking coal,
Tracked jaw crusher is mainly used for hard rock crushing, aggregate production, open pit mining, waste crushing and recycling, cement production, tunnel broken, etc.
Powder grinding plant is also called powder making plant, which is widely used for the powder making in mining, power, chemical industry, building materials, metallurgy, refractory materials,
As a pure natural stone with high usage value, river gravel is formed in the long-term impact, squeeze and friction function. River gravel generally shows the color of black, white, yellow, red, green gray, etc.

In the direct route coal is pulverized and reacted with a catalyst then hydrogen is added under high pressures and temperatures in the presence of a solvent to produce a raw liquid fuel This raw fuel requires refining in order to yield acceptable transportation fuels Check out the video below for a visual explanation of the liquefactionFurther Details
One of the advantages of direct liquefaction is that this process can convert coal to liquid without the need for producing syngas H 2 and CO as in indirect process and also has higher efficiency than indirect liquefactionFurther Details
economically attractive coal conversion technology Key advantages economically competitive 3045bbl low capital requirements 15Kbpd virtually zero CO 2 emissions no water consumption very high feed and product ﬂexibility direct conversion of domestic coalFurther Details
Jan 13 2014 · ii Direct coal liquefaction The Bergius process reaction 21 forms the chemical basis of DCL Thermal energy is used to induce homolytic bond scissions in coal molecules to produce free radicals that can subsequently isomerize decompose or be used in other chemical reactions normally performed at high temperature and pressures 24 28Further Details
Coal liquefaction has historically been used in countries without a secure supply of petroleum such as Germany during World War II and South Africa since the early 1970s The technology used in coal liquefaction is quite old and was first implemented during the nineteenth century to provide gas for indoor lighting Speight 2013aFurther Details
Nov 01 2008 · The CLR sample used in the present study was obtained from a pilot setup for direct liquefaction of Shenhua coal in China of which the proximate and ultimate analysis data and mineral analysis data are shown in Table 1 Table 2 CLR sample without any pretreatment was packed into a container that was placed under the nozzle of plasma jet in the reactorFurther Details
When tar is collected to be used as a fuel the process is the called liquefaction of the coal into tar oil You need also to know about the technology known as coaltoliquid CTL is where coalFurther Details
