ABSTRACT:
A liquefaction process for coal or lignite is set forth. In the preferred and illustrated embodiment, coal or lignite is ground to a suitable particle size and placed in a reactor vessel. The reactor vessel is located within a pressure vessel. Pressure in the vessel is reduced to about 10.sup.-2 torr.
Heat is applied. One procedure is to convert the carbon (in the coal or lignite) at an elevated temperature (600.degree.-900.degree. F.) in the presence of hydrogen (at pressures as high as 2,000 psi) into a hydrocarbon mix; depressurization avoids making various oxides and nitrides, and also can be optionally carried out in the presence of iron or iron ore in particulate form acting as a catalyst.
