Production of oil by pyrolysis of coal

A method of producing oil from coal by pyrolysis;

• said method comprising the steps of:
• (a) cleaning the surface of one or more metallic substrate particles, wherein each metallic substrate particle has a longest dimension between about 100 μm and about 5 mm;
• (b) oxidizing or nitriding the surfaces of the metallic substrate particles, to covalently attach oxide or nitride groups to the surfaces of the metallic substrate particles;
• (c) covalently bonding one or more linker groups to the oxide, to the nitride, or to the metal surface;
• (d) covalently bonding one or more seed layers to the one or more linker groups, wherein the one or more seed layers comprise ruthenium, rhodium, palladium, silver, osmium, iridium, platinum, gold, copper, rhenium, mercury, aluminum oxide, or nickel(II) oxide;
• (e) covalently bonding a catalyst layer to the one or more seed layers, wherein the catalyst layer comprises a metal, a metal oxide, a doped metal, or a zeolite;
• wherein the resulting catalyst/support composition is adapted to directly absorb electromagnetic energy from microwave irradiation, or electromagnetic induction, or both, and thereby to be rapidly heated to a temperature between about 250° C. and about 1000° C.;
• (f) heating the catalyst/support composition to a temperature between about 250° C. and about 1000° C. by microwave irradiation, or by electromagnetic induction, or both, in an inert atmosphere inside a reactor;
• (g) contacting coal with the heated catalyst/support composition for a time sufficient to transform at least a portion of the coal into oil vapors;
• wherein the catalyst/support composition is hotter than the coal;
• and
• (h) condensing the oil vapors, and collecting the resulting liquid oil.
