Abstract

FIELD: production of adsorbents, petrochemistry, chemical industry and metallurgy, purification of sewage against various impurities. SUBSTANCE: activated granulated coal is impregnated with saturated aqueous solution of ammonium thiocyanate, potassium thiocyanate or sodium, urea or thiourea and is allowed to stand within 5-6 h. Then heat treatment within 2.5-3 h at 310-370 C is carried out. EFFECT: increased sorption capacity of modified activated coal, simplified the method.

Изобретение относится к способам получения активного угля и может быть использовано в производстве адсорбентов, в нефтехимической, химической, металлургической промышленности, а также в области очистки сточных вод от органических и других загрязнений. Задачей изобретения является разработка эффективного безопасного способа получения модифицированного угля, обладающего высокой сорбционной емкостью по отношению к органическим соединениям. Задача решается следующим образом. Активированный гранулированный уголь пропитывают насыщенным водным раствором роданистого аммония, роданистого калия или натрия, мочевины или тиомочевины, выдерживают 5 - 6 ч и подвергают термообработке при 310 - 370oС в течение 2,5 - 3,0 ч. Разработанный способ обеспечивает значительное повышение сорбционной емкости модифицированного активного угля по сравнению с исходным углем. В отличие от обработки активного угля аммиаком его поверхность приобретает положительный заряд, необходимый для сорбирования молекул органических соединений. Способ прост, эффективен, безопасен и не требует специального сложного оборудования для осуществления.The invention relates to methods for producing activated carbon and can be used in the production of adsorbents, in the petrochemical, chemical, metallurgical industries, as well as in the field of wastewater treatment from organic and other contaminants. The objective of the invention is to develop an effective safe method for producing modified coal having a high sorption capacity with respect to organic compounds. The problem is solved as follows. Activated granular carbon is impregnated with a saturated aqueous solution of rhodanide ammonium, rhodanide potassium or sodium, urea or thiourea, incubated for 5-6 hours and subjected to heat treatment at 310 - 370 o C for 2.5 - 3.0 hours. The developed method provides a significant increase in sorption capacity of modified activated carbon compared to the source coal. In contrast to the treatment of activated carbon with ammonia, its surface acquires a positive charge, which is necessary for the sorption of molecules of organic compounds. The method is simple, efficient, safe and does not require special sophisticated equipment for implementation.
