description The invention provides a method for extracting high purity hydrogen from coke oven gas reformed gas; an ultra-highly hydrogen-permeation-selective metal palladium composite membrane hydrogen purification device is used, the high purity hydrogen is obtained from the coke oven gas reformed gas under the conditions guaranteeing high hydrogen recovery rate. The coke oven gas reformed gas first enters a buffer tank, then enters a compressor for pressure rise, then successively passes through a filter and an electric heater to enter into the metal palladium composite membrane hydrogen purification device, and is cooled by a cooler to obtain the high purity hydrogen with the purity greater than 99.999%, the CO content is less than 1.0ppm, and at the same time, because of high hydrogen permeation rate of the metal palladium composite membrane, a higher raw gas treatment amount can be obtained under the conditions of the recovery rate being more than 90%, and full utilization of the coke oven gas can be achieved.
