Activated carbons from co-mingled liquid and solid organic wastes

Data on a synergetic phenomena of the components of the co-mingled solid and liquid wastes occurs during their thermolysis were used for the development of the co-activation approach to wastes recycling. Co-activation was aimed at generation of porous solid valuable secondary products (activated carbons). The development of the design parameters for the activated carbons syntheses was done at valorization of the re-polymerization, re-association and the polycondensation reactions between the reference structural fragments of the components in the ternary composite systems "Spent Petroleum Product Waste – Biomass – D-grade coal#x0022; and #x0022;Coal Processing Sludge – Biomass – D-grade coal#x0022;. From elaborated comprehensive investigations the main factors, which influence the carbonized chars formation and the properties of the resulted activated carbons were evaluated. The porous solid secondary products of uniform particle size and pore size distribution were obtained during co-processing in the co-mingled systems. The surface area is ranged between 600-1100 m²/g, the total pore volume is of 0.32-0.47 m³/g and the yield is of 21-27%. Additionally, an efficiency of the catalytic co-processing of natural organic solid and liquid wastes with coal in a presence of the K/Na carbonates was studied aiming at novel adsorbents usage for wastewater purification from heavy metals.
