Coal: liquefaction (Journal Article) OSTI.GOV

One of several direct liquefaction processes currently under advanced stages of development is the Solvent-Refined Coal-I (SRC-I) process. A major SRC-1 product option is a low sulfur, low ash solid (SRC) which could be used as an electric utility boiler fuel much in the same manner that pulverized coal is currently fired in this type of combustion equipment.

REVIEW ON DIFFERENT TECHNOLOGIES FOR COAL

2016-5-22  The oldest method for obtaining liquids from coal is high temperature pyrolysis. Typically, coal is heated to around 950° C in a closed container. The heat causes decomposition and the volatile matter is driven away, increasing carbon content. This is similar to the coke-making process and accompanying tar-like liquid is mostly a side product. The process results in very low liquid yields and upgrading costs are relatively high. Coal tar is not traditionally used as a fuel in the transportation sector. However, it is used worldwide for manufacturing roofing, waterproofing and insulation products and as a raw material for various dyes, drugs and paints. Mild temperature pyrolysis uses temperatures of 450-650 °C. Much of the volatile matter is driven off and other compounds are formed through thermal decomposition. Liquid

Direct Coal Liquefaction - an overview ScienceDirect Topics

This direct coal liquefaction process has been piloted by the American Exxon Company at its Baytown Refinery in Texas (Exxon EDS, 1981). The stages of the process are shown in Fig. 4.66.Coal is slurried with hydrogenated recycle oil. The coal-oil slurry is passed via a preheater to a simple reactor at 410 °C together with high pressure hydrogen (150 bar).
