| 摘要 |
The invention relates to a method (10) for treating a synthesis gas from a gasification step, which includes: a step (105) of cooling the synthesis gas in order to condense heavy organic impurities and water; a step (110) of adsorption, at the end of the cooling step, of light organic impurities and inorganic impurities by at least one adsorption bed (230); a step (155) of separation, by decantation (135), of the water and heavy tars from the step (105) of cooling the synthesis gas; and a step (120) of regenerating at least one adsorption bed (230) by temperature-modulated or pressure-modulated desorption. |
