Process for producing an active carbon matrix impregnated with an inorganic acid for use as a chemical adsorbent from a carbonaceous lignocellulosic biomass material, comprising the step of applying an inorganic acid to the carbonaceous biomass material while mixing both components, comprising inorganic acid hydrochloric acid, nitric acid, phosphoric acid or sulfuric acid with a strength of 75% to 100% concentrated inorganic acid and applied in a ratio between 1: 1 and 10: 1 by weight of the biomass material carbonaceous, characterized in that the conversion of the carbonaceous material into active carbon and the impregnation of acid are carried out in one step, without further processing of the matrix of active carbon impregnated with acid by heat treatment, washing, neutralization or a subsequent sulfonation step Of gas. |
