Coal Plants Utilize Fisher® Regulators for Precise Pressure Control

Clean Coal Technology Industry Overview

Coal is an abundant, reliable, and inexpensive source of energy, but
it does have some technical limitations. Coal is not suitable for use
in some applications such as transportation and it produces a range
of environmental pollutants when burned. In recent years, several
clean coal technologies have been developed to help reduce the
environmental pollution caused by burning coal and make coal
more energy-efficient. Among these, coal gasification and coal
liquefaction are the most popular technologies to date.

Common Clean Coal Technologies

Coal gasification is considered one of the most versatile and
cleanest ways to convert coal into an alternative and cleaner form

of energy. In gasication, coal is broken down to its basic chemical

constituents rather than directly burned. The resulting syngas (a gas
mixture made up of carbon monoxide, hydrogen, and other gaseous
compounds) can be used as a fuel source or as an intermediate for
the production of other chemicals.

Coal liquefaction converts solid coal to synthetic oil to supplement
natural sources of petroleum. This well-developed technology

requires coal to be in contact with hydrogen in the presence of a
catalyst at high temperatures. Coal liquefaction can either be direct
as described previously or indirect. Indirect coal liquefaction consists
of two stages: gasification to produce coal gas and subsequent
conversion of the gas to liquid via the Fischer-Tropsch process.

Products derived from coal through these clean coal technologies can
be used as fuel for transportation vehicles and electricity generation,
and as raw materials to other valuable products. These recent
developments in the clean coal industry can also help ease the burden
of oil production and import.
