Abstract

FIELD: chemical technology. SUBSTANCE: carbon-containing waste of graphitized electrodes are activated in the presence of catalyst at 790-810 C with steam at its consumption 0.8-1.0 kg/kg waste. EFFECT: improved method of active carbon producing.

Description

Изобретение относится к изготовлению сорбентов для очистки вод от органических и неорганических загрязнений, в частности к способу получения активного угля из углеродсодержащего материала. The invention relates to the manufacture of sorbents for water purification from organic and inorganic pollution, in particular to a method for producing activated carbon from a carbon-containing material.

Известен способ получения активного угля, включающий активацию буроугольного кокса в печи водяным паром при его расходе 1,4-1,9 кг/кг кокса в присутствии катализатора при 800-1000оС в верхней части печи, 800-970оС в средней части печи и 720-920оС в нижней части печи.A method of producing active coal, comprising the activation of lignite coke oven with steam at a flow rate of 1.4-1.9 kg / kg of coke in the presence of a catalyst at about 800-1000 C in the upper part of the furnace of 800-970 C in the middle part furnace and 720-920 about With in the lower part of the furnace.

Техническим результатом заявленного способа является удешевление процесса. The technical result of the claimed method is to reduce the cost of the process.

П р и м е р 1. В трубчатую печь загружают 1 кг углеродсодержащих отходов производства графитированных электродов (графитированный кокс) и нагревают их до 790оС. Затем в печь подают катализатор в виде 15%-ного водного раствора карбоната калия при расходе 0,08 кг карбоната калия/кг отходов и водяной пар при его расходе 0,8 кг/кг отходов. Сорбционная емкость полученного активного угля по уксусной кислоте 1,34 ммоль/г.EXAMPLES EXAMPLE 1. In a tube furnace was charged with 1 kg of carbonaceous graphite electrode production waste (graphitized coke) and heated them to 790 ° C. Then, the furnace is fed to the catalyst as a 15% aqueous potassium carbonate solution at a flow rate of 0, 08 kg of potassium carbonate / kg of waste and water vapor at its consumption of 0.8 kg / kg of waste. The sorption capacity of the obtained active carbon in acetic acid is 1.34 mmol / g.

П р и м е р 2. Аналогичен примеру 1 за исключением того, что активацию ведут при 800оС и расходе пара 0,9 кг/кг отходов. Сорбционная емкость полученного активного угля по уксусной кислоте 1,37 ммоль/г.PRI me R 2. Similar to example 1 except that the activation is carried out at 800 about With a steam consumption of 0.9 kg / kg of waste. The sorption capacity of the obtained active carbon in acetic acid is 1.37 mmol / g.

П р и м е р 3. Аналогичен примеру 1, но активацию отходов ведут при 810оС и расходе пара 1,0 кг/кг отходов. Сорбционная емкость полученного активного угля по уксусной кислоте 1,36 ммоль/г.PRI me R 3. Similar to example 1, but the activation of waste is carried out at 810 about C and a steam consumption of 1.0 kg / kg of waste. The sorption capacity of the obtained active carbon in acetic acid is 1.36 mmol / g.
