NOVELTY - A coke is added in gasification stove fall winding to carry out the gasification reaction, to obtain gas. The composition is added, dust and tar from the stored water gas are removed, pressurized at 0.059 MPa, and sulfurated hydrogen and organic sulfur are removed. The cobalt molybdenum catalyst is added into the inorganic sulfur, and rectification of methanol is carried out by removing the low boiling component in the pre-distillation, and removing the high boiling component in the atmospheric distillation, to obtain alcohol ether fuel.    USE - Synthesis of alcohol ether fuel.    ADVANTAGE - The alcohol ether fuel is synthesized economically.    DETAILED DESCRIPTION - A coke is added in gasification stove fall winding to carry out the gasification reaction by blowing, blowing off steam, up-winding to prepare gas, fall winding to prepare gas, secondary steam up-winding and blowing off air, after winding and dusting, reclaiming heat quantity, after the prepared water gas dusting, reclaiming remaining heat, after re-dusting, reducing temperature to 40 degrees C or lower for storage. The composition comprising (in vol%) hydrogen (48-53), carbon monoxide (34-40), carbon dioxide (5-10), methane (0.5-1.1), mixture of nitrogen and argon (1-5), oxygen (0.2-0.5), and sulfur (2-6 g/Nm) is added, dust and tar from the stored water gas are removed, pressurized at 0.059 MPa, and sulfurated hydrogen and organic sulfur are removed. The cobalt molybdenum catalyst is added into the inorganic sulfur, re-desulfurized, absorbed and the micro-sulfur is removed. The reaction mixture is subjected to hydrogen distillation at 0.2 MPa, naphthalene, sulfur, benzene, hydrogen cyanide, ammonia and tar are removed, and the components of nitrogen, methane, carbon monoxide, and carbon-dioxide are absorbed. The synthesis of methanol is reacted with carbon monoxide and carbon-dioxide, at 5.4 MPa and 190-290 degrees C. The rectification of methanol is carried out by removing the low boiling component in the pre-distillation, and removing the high boiling component in the atmospheric distillation, to obtain alcohol ether fuel.
