Abstract
A lack of highquality carbon adsorbents CA with a uniform microporous structure is the main impediment to the development of new and the improvement of existing adsorption methods for purifying and separating gases The sorbent structure ie the size volume and ratio of principal pore types is determined by the nature of the precursor and its processing into activated carbonAs a rule the porosity of carbonized carbons from wood and plant material is known to be disorganized Structure formation in a particular direction is difficult to regulate accurately The sizes and distribution of pores in CA could possibly be controlled by modifying the porosity of finished activated carbon with an organic binder and/or a poreformer or by applying a layer of organic polymer or hydrocarbon thermal decomposition products to the carbon substrate 1
