Coal-to-oil plants were constructed in a number of other countries, but only one plant in South Africa is still producing liquids from coal. Liquid production from coal by the Bergius hydrogenation process involved the reaction of hydrogen with a mixture of coal and oil (made in the process) at high temperatures and pressures.
