4A1. Coal Liquefaction Technology Development in Japan

indirect coal liquefaction method to study coal liquefaction technology and to produce synthetic oil. The Fischer-Tropsch Process was introduced into Japan upon its announcement in Germany in 1935 and, in 1937, the construction of a plant commenced in Miike. This oil synthesis plant was completed in 1940, with an annual production capacity of 30,000 tons of coal oil. Under the backdrop of war ...

Coal Liquefaction | The Canadian Encyclopedia

Coal liquefaction is a process that converts coal from a solid state into liquid fuels, usually to provide substitutes for petroleum products. Coal liquefaction processes were first developed in the early part of the 20th century but later application was hindered by the relatively low price and wide availability of crude oil and natural gas. Large scale applications have existed in only a few ...

Mechanical properties were studied by tensile test of Ti-15V-3Cr-3Sn-3A1 alloy obtained by duplexaging after cold-swaging, i.e. aging at higher temperatures followed by reaging at a lower temperature. Combinations of short-time aging at 823 K, 873 K and 923 K and reaging at 673 K have improved strength-ductility balance of this alloy greatly, realizing high strength of about 1.8 GPa with ...

Coal liquefaction - Energy Education

Coal liquefaction is a process in which coal is converted into liquid fuels or petrochemicals. There are several processes used to accomplish this task, the two most common being the "indirect route" and the "direct route". The indirect route is composed of 2 steps: First, coal is gasified with steam and oxygen to produce a synthesis gas (syngas), which is then cleaned to rid of dust, tar, and ...

Coal Liquefaction - an overview | ScienceDirect .

Coal liquefaction is the process of making a liquid fuel from coal. The fundamental difference between coal, a solid, and liquid fuels is that the liquid fuels have a higher hydrogen:carbon ratio. Liquid fuels have lower ash contents and are easier to upgrade (i.e., to remove unwanted impurities such as nitrogen and sulfur). There are three major methods of producing liquid fuels from coal ...

COAL: LIQUID FUELS

Direct coal liquefaction converts coal to a liquid by dissolving coal in a solvent at high temperature and pressure. This process is highly efficient, but the liquid products require further refining ('hydrocracking' or adding hydrogen over a catalyst) to achieve high grade fuel characteristics. Indirect coal liquefaction first gasifies the ...
