Coal-to-Liquids and Lignite-to-Liquids - An Environmentally-Sound Solution f..
- The possibility of the world facing a "peak oil crisis" is now widely
recognized as a clear and present danger in the fields of fuel and
Unfortunately, many attractive and widely-touted alternate fuel
systems -- such as a safe and practical hydrogen-based transport fuel
system -- will remain a dream until the distant future.
For this reason, many nations have been re-examining other transport
fuel technologies, such as the Coal-to-Liquids (CTL) technology, as a
near future source of transport fuels.
Coal-to-Liquids -- that is, the conversion of coal to liquid
transport fuels -- is in fact not new a technology and has been
practiced for a number of decades in countries such as South Africa
and Germany and will soon be adopted in China.
The most viable Coal-to-Liquids system requires the conversion of
coal into a synthesis gas consisting of hydrogen and carbon monoxide
and then its synthesis into long-chain liquid fuel molecules. These
processes produce excess heat that can be used to generate
electricity. The synthetic petroleum products, and especially
synthetic diesel, have a number of unique environmental advantages.
These advantages include the reduction of particulates, nitrogen
oxides and fugitive aromatic hydrocarbon emissions of those
associated with 'natural crude'....
