ADSORBENT FOR HIGH-BOILING POINT HYDROCARBONS AND METHOD FOR CONTINUOUS REMOVAL OF HYDROCARBONS USING THE SAME ADSORBENT

摘要

Purpose: an adsorbent adsorbs and is removed from an ironworks the high boiling hydrocarbon movement for being contained in a coke-stove gas, is arranged to improve absorption property for high boiling hydrocarbon movement. Construction: the adsorbent for the movement of high boiling hydrocarbon includes one or more transition metal, is carried by an activated carbon fibre or an activated carbon. A kind of method, for including the following steps: to introduce gas in the continuous removal for containing the higher boiling point hydrocarbon compound movement in a kind of identical gas to the first adsorption column, high boiling hydrocarbon movement is adsorbed containing adsorbent and discharges purification gas; Gas is introduced in constant temperature simultaneously to arrange to second adsorption, is decomposed and is moved by adsorbent absorption at high boiling hydrocarbon of water and CO2 and discharge them to recycle adsorbent. Optionally first and after-fractionating tower execute adsorption step and recycling step.
