The second plant at Louisiana, MO, was completed in 1950 and began full operation in 1951. Almost from day one, however, the 80barrel per day test facility was plagued by disintegration of the chemical catalysts used to convert the coal gas into liquid fuels. Only 40,000 gallons of liquid products were produced by the 5 million plant.

Gasification is a technological process that can convert any carbonaceous (carbonbased) raw material such as coal into fuel gas, also known as synthesis gas (syngas for short). Gasification occurs in a gasifier, generally a high temperature/pressure vessel where oxygen (or air) and steam are directly contacted with the coal or other feed material causing a series of chemical reactions to ...

Answer Explanation. All tutors are evaluated by Course Hero as an expert in their subject area. Liquefaction is the process of converting solid coal into liquid fuels. The main difference between naturally occurring petroleum fuels and coal is the deficiency of hydrogen in the latter: coal contains only about half the amount found in petroleum.
