Abstract

See full text

A method for treating a synthesis gas from a gasification step. The synthesis gas is cooled to condense heavy organic impurities and water. At the end of the cooling step, light organic impurities and inorganic impurities are adsorped by at least one adsorption bed. The water and heavy tars are separated by decantation from the step of cooling the synthesis gas. At least one adsorption bed is regenerated by temperature-modulated or pressure-modulated desorption.
