    Abstract: Disclosure is made of an apparatus for reacting carbonaceous material with heated hydrogen to form hydrocarbon gases and liquids suitable for conversion to fuels wherein the reaction involves injection of carbonaceous material such as pulverized coal entrained in a minimum amount of gas and mixing the entrained coal at near ambient temperature with a separate source of heated hydrogen. The hydrogen is heated in a coil having an increasing inside diameter. The heated hydrogen and entrained coal are injected through a rocket engine type injector device. The coal particles are reacted with hydrogen in a reaction chamber downstream of the injector. The products of reaction are rapidly quenched as they exit the reaction chamber and are subsequently collected.
