NOVELTY - Comprehensive utilization of crushed coal pressure gasification synthetic gas involves crushing coal pressure gasification synthetic gas, adjusting hydrogen-carbon ratio, carrying out low temperature methanol washing, performing methane depth cold separation, taking parts of obtained gas under pressure swing adsorption, stripping gas, carrying out methanol synthesis on gas not subject to pressure swing adsorption to form gasoline, using hydrogen in hydrogenation and cracking of tar, and using heavy oil and naphtha byproducts to prepare gasoline, diesel oil and heavy oil products.    USE - Method for comprehensive utilization of crushed coal pressure gasification synthetic gas used for production of gasoline and liquefied natural gas through methanol synthesis, and tar depth processing (claimed).    ADVANTAGE - The method has high utilization rate, high simplicity, reasonable product structure and small environmental pollution.    DETAILED DESCRIPTION - Comprehensive utilization of crushed coal pressure gasification synthetic gas comprises crushing coal pressure gasification synthetic gas, adjusting hydrogen-carbon ratio, carrying out low temperature methanol washing to remove carbon dioxide and hydrogen sulfide and other acidic gases, performing methane depth cold separation to remove methane gas and produce liquified natural gas as byproduct, taking parts of obtained gas under pressure swing adsorption to remove hydrogen, stripping gas, taking gas not subject to pressure swing adsorption and carrying out methanol synthesis to form gasoline, taking hydrogen and using in hydrogenation and cracking of tar, and using heavy oil and naphtha byproducts of crushed coal pressure gasification to prepare gasoline, diesel oil and heavy oil products.
