CharFuel® Coal Refining Process Carbon Fuels

Coal and crude oil are both hydrocarbons. They can be refined in the same manner. Like crude oil, coal produces transportation, heating fuels, electricity generation feedstock (char), and petrochemicals. Refining coal using the CharFuel ® Coal Refining Process removes pollutants from char prior to combustion or gasification.

The U.S. coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity. Despite the industry’s importance, industry financial data for 2005—the strongest year for the coal industry in recent years—shows that it is a relatively small industry with revenues totaling $20 billion to $25 billion and net income between $1 billion and $2

Refining of petroleum Class 8, Coal and Petroleum

Sep 26, 2016 Refining of petroleum. The crude petroleum oil is a complex mixture of solid,liquid and gaseous hydrocarbons. So before petroleum can be used for specific purpose,it has to be refined or purified. The process of separating crude petroleum oil into more useful fractions is called refining.

How Coal Works Union of Concerned Scientists

Dec 15, 2017 If coal is high in sulfur or other impurities, it is washed with a water or chemical bath, removing up to 40 percent of inorganic sulfur in the coal. Not all coal is prepared using the same process. High-sulfur coal commonly undergoes washing to meet environmental regulations, while low-sulfur coal is often crushed and resized without being washed.

The formation of petroleum Pennsylvania State University

There are two different methods for converting coal into liquid fuels, direct and indirect liquefaction. The direct liquefaction method dissolves the coal in a solvent at high temperature and pressure. While highly efficient, the liquid products generated this way require further refining to achieve a high fuel grade.
