    摘要: An apparatus for producing high surface area active carbons in a safe and commercially advantageous manner by the alkali metal hydroxide-based activation method is provided. Using pushers (9a-k), the apparatus circulates containers (C) along a container travel line (8) connecting the elements: material feeding section (1).fwdarw.inlet side gas replacement chamber (2).fwdarw.tunnel kiln (3).fwdarw.cooling zone (4).fwdarw.water injection chamber (5).fwdarw.outlet side gas replacement chamber (6).fwdarw.reaction mixture discharge port (7) to form a closed circuit. During the travel of the containers, a series of steps is performed, namely the steps of charging of the containers with raw materials (carbonaceous material and alkali metal hydroxide-water mixture), dehydration, activation of the carbonaceous material with the alkali metal hydroxide, cooling, water injection and discharge of the reaction mixture. The gas exhaustion system for the tunnel kiln (3) and water injection chamber (5) is provided with a water seal (10).

    摘要: In a gas refining method using a PSA method, a cleaning step is divided into a preparatory cleaning step and a substantial cleaning step, and an exhaust gas (particularly a high concentration gas obtained in the latter half is effective) obtained in the substantial cleaning step is used as a gas to be admitted into an adsorption column in the preparatory cleaning step. This method is employed, for example, to refine carbon monoxide from a material gas containing carbon monoxide. Accordingly, the gas refining method using the PSA method can ensure a specified amount of collected gas product without resulting in an increase in the amount of adsorbent even if a low concentration material gas is used.
