Porous carbonaceous materials from pine sawdust modified with FeCl3, ZnCl2 and H3PO4 have been synthesized. A comparative analysis of their structure and properties at different temperatures of carbonization and subsequent a treatment water has been carried out using thermal adsorption of nitrogen for determine of specific surface, electron microscopy and X-ray analysis.It was revealed that homogeneous amorphous-crystalline structure of product is formed in heating of samples with H3PO4; carbonization of samples with FeCl3 leads to formation of crystalline phases including magnetite, but carbonization of samples with addition of ZnCl2  creates basic two phases – amorphous-crystalline and hexagonal crystallites of zinc oxide that impart special properties of the products.It has been shown that the addition of ferric chloride allows to obtain magnetite/carbon composite having a specific surface area of 470 m2 g-1; the addition of zinc chloride in biomass leads to the formation of a zinc oxide/carbon composite having a specific surface of 1900 m2 g-1; and the addition of phosphoric acid results polyphosphate-carbon structure with a specific surface area up to 1300 m2 g-1. It has been revealed that the porosity of the product is associated mainly with the formation of the water-insoluble of crystal-like fragments for carbonization.
