Diesel fuel is the common term for the distillate fuel oil sold for use in motor vehicles that use the compression ignition engine named for its inventor, German engineer Rudolf Diesel. He patented his original design in 1892. Diesel fuel is refined from crude oil and from biomass materials. One of the fuels that Rudolf Diesel originally ...

Biomass-, coal-, gas- and waste-to-liquids (XTL) processes are slowly making inroads, but the global contribution from these sources to liquid transport fuel production is still <5 %. The current global demand for crude oil is around 5.2×10 9 m 3 ·a −1, which is equivalent to 90 million barrels per day (bpd) [1] .

of liquid fuels will be required. Coal liquefaction is one source, and is backed by large recoverable coal reserves globally. These reserves are indeed significantly greater than for other fossil fuels. Development History The production of coal-derived liquids as a by-product of coke-making commenced in Germany and the UK in the 1840s. These ...

The process of coal liquefaction creates synthetic liquid fuels from solid coalas substitutes for various petroleum products. There are two types of liquefaction – direct and indirect1. Direct liquefaction converts solid coal directly into liquid form with no intermediate step, which results in only the partial dismantling of the coal structure.

For the same kind of coal-derived fuel production technology using a different mining–transport–production pathway, there is no significant difference in the equivalent CO 2 emissions (Fig. 7.10). This is because CO 2 emissions are mainly concentrated in coal mining and liquid fuel production links.
