The utility model relates to a device of production H2CO feed gas, in particular to process units by the feed gas of coke oven gas, blast furnace gas, the synthetic ethylene glycol of converter coal gas preparation belongs to the chemical engineering technology field. Include: pressure swing adsorption separator for separation CO and N2, diverging device connects in pressure swing adsorption separator to be equipped with CO export and the export of the 2nd CO, be used for the CO who obtains the separation to divide into two strands, shift reactor connects the export in separator's a CO for carry out the transformationreation and make H2 obtaining CO. Can accord with the preparation of blast furnace gas warp the purpose of required ethylene glycol feed gas from this, simultaneously also canby -product nitrogen gas. The utility model has the advantages of energy saving and emission reduction, environmental protection, process flow is simple, the equipment investment is few and the products that yield a high add
