ABSTRACT:
A process of catalytic coal gasification characterized by mixing an inexpensive, low rank coal with an aqueous solution of inexpensive, widely existing alkali metal or alkaline earth metal chlorides, such as Nacl, KCl, or the like; adding a pH adjustor such as ammonia to the resulting mixture to adjust pH to 5.about.12, whereby an ion exchange is effected between said metal and hydrogen in the coal, thereby loading only metals as a catalyst on the coal; washing the coal with water to remove chloride by-products; and running steam onto the catalyst-loaded coal at high temperatures and high pressures.
