NOVELTY - Coke-oven gas using involves purifying a material by removing naphthalene, benzene and tar to obtain purified coke-oven gas. The purified coke-oven gas is processed in presence of catalyst through pre-heater, intermediate heat exchanger, shift converter, converter and humidifier. Carbon monoxide of coke-oven gas is converted into hydrogen. Oxygen and other impurities are removed from coke-oven gas. Organic sulfur of coke-oven gas is converted into inorganic sulfur to obtain a converted gas. The pre-heating process involves compressing the purified coke-oven gas at 0.6-2.5 MPa.    USE - Method for using coke-oven gas and coal as materials for producing synthesis gas for producing methanol and compressed natural gas (claimed).    ADVANTAGE - The coke-oven gas using method is cost-effective and enables to prepare methanol and compressed natural gas.    DETAILED DESCRIPTION - The coke-oven gas using involves purifying a material by removing naphthalene, benzene and tar to obtain purified coke-oven gas. The purified coke-oven gas is processed in presence of catalyst through pre-heater, intermediate heat exchanger, shift converter, converter and humidifier. Carbon monoxide of coke-oven gas is converted into hydrogen. Oxygen and other impurities are removed from coke-oven gas. Organic sulfur of coke-oven gas is converted into inorganic sulfur to obtain a converted gas. The pre-heating process involves compressing the purified coke-oven gas at 0.6-2.5 MPa. The converted gas is pre-heated in the pre-heater at 115-165 degrees C. The heat is exchanged between pre-heated coke-oven gas and converted gas in the intermediate heat exchanger at 200-260o?C. Vapor is added to the heat-exchanged coke-oven gas. The shift converter is equipped with purificant, deoxygenation protecting agent, hydrogenation catalyst and shift catalyst. A process gas is processed by purificant and deoxygenation protecting agent. Naphthalene, benzene, oil stain and oxygen are removed from the coke-oven gas. Hydrogenation catalyst and shift catalyst layer are entered into the coke-oven gas at 340-420 degrees C. The humidifying and cooling process involves introducing gas from the shift converter into the humidifier. Cold shocking water is injected into the humidifier for humidifying and cooling at 210-280 degrees C. The heat exchanging and cooling process involves introducing converted gas from shift converter into the intermediate heat exchanger. The pre-heating coke-oven gas is purified and cooled at 190-240 degrees C. The pre-heating coke-oven gas is further cooled at 40 degrees C. Desulfurizing and decarbonising processes are used, which involves utilizing low temperature methanol washing process or domestic mature technology or other wet desulfurizing and decarbonising processes. Sulfur is reduced in the converted gas after transformation process. The mixed gas is separated after desulfurizing and decarbonising through pressure varying adsorption to obtain methanol enriched gas containing 90% of methanol and hydrogen enriched gas containing 98% of hydrogen. The methane enriched gas is pressurized at 25-30 MPa to obtain compressed natural gas. The material coal is gasified by an existing technology to obtain water gas. The water gas comprises carbon monoxide, hydrogen and carbon dioxide. The water gas is purified to obtain purified water gas. The purified water gas is mixed with hydrogen enriched gas. A mixture of water gas and hydrogen gas are desulfurized in presence of hydrolytic agent and dry desulfurizing agent at 0.6-2.5 MPa and normal temperature to obtain virgin gas.
