The adsorption separation device based on the multi-channel material distribution valve comprises an adsorption tower, a pretreatment tower, a first fractionating tower and a second fractionating tower, the adsorption tower sequentially comprises a desorption area, a refining area, an adsorption area and an isolation area from top to bottom, and the desorption area, the refining area, the adsorption area and the isolation area are all composed of a plurality of bed layers; the bed layer comprises a feed port, an extract port, a raffinate port, a reagent liquid adding port and a cleaning liquid port; and the feed port, the extract liquid port, the raffinate port, the agent liquid adding port and the cleaning liquid port between the bed layers are respectively connected through a multi-channel material distribution valve. By setting each bed layer of the adsorption tower and the connection relationship between the bed layers, low-temperature, low-pressure, non-hydrogen and pure physical adsorption separation an
