Influence of modifying additives on formation of the porous structure of peat coke

Experimental data on the influence of the additives of some inorganic reagents, having direct effect on the formation process of the porous structure of carbon materials are given in the article. It is shown that inorganic modifiers (zink chloride and orthophosphoric acid) influence on the process of peat thermal destruction, change the output of final products. Semi-coke output increases in comparison to non-modified peat and liquid and gaseous decrease what evidences the conservation of the significant part of carbon and oxygen in the fossil residues of pyrolysis. Thermal analysis data evidence more low temperatures of the course of structure formation in the coke residue of modified peat. Peat modification contributes to the direct formation of the pore structure of the products of peat coking. Intense creation of micro porous take their place as the result of samples thermal destruction containing 50 and 100 % of zink chloride during 600 ºС temperature. Semi-coke samples on sorption activity on iodine are close to commercial activated carbons. Intense creation of micro-porous during peat thermal destruction modified by orthophosphoric acid in the amount of 50 and 100 % take place during 450 ºС temperature when organic substance loss in the form of volatile products is observed.
