Переработка углистого колчедана, представл ющего собой отход добычи угл , путем обжИга на сернистый ангидрид обеспечивает получение сернистого газа, пригодного дл  выработки серной кислоты.The processing of carbonaceous pyrites, which is a waste of coal mining, by burning to sulfuric anhydride ensures the production of sulfur dioxide suitable for the production of sulfuric acid.

Известный способ переработки углистого колчедана заключаетс  в смешивании его с безуглистым колчеданом и обжиге смеси с получением сернистого ангидрида.A known method for processing pyritic pyrites is to mix it with a limeless pyrites and roast the mixture to produce sulfur dioxide.

Основным недостатком известного снособа  вл етс  мала  концентраци  ки-слорода в газовой смеси и вследствие этого уменьшение оптимальных концентраций сернистого ангидрида до 6%. В результате имеет место низка  производительность нроцесса получени  серной кислоты.The main disadvantage of the known procedure is the low concentration of oxygen-ki in the gas mixture and, as a result, a decrease in the optimal concentrations of sulfur dioxide to 6%. As a result, the productivity of sulfuric acid production is low.

По предлагаемому способу обжнг ведут в присутствии сульфата железа при его весовом отношении к углероду колчедаиа, равном 5-23:1.. According to the proposed method, obryng are carried out in the presence of iron sulfate with its weight ratio to pyrite carbon equal to 5-23: 1.

Способ заключаетс  в следуюш,ем.The method is as follows.

Обжиг обогащенного углистого колчедана с со.хранением 42-45% серы и 8-10% углерода ведут в присутствии сульфата железа, который берут в отношении к содержащемус  в колчедане углероду, равном 5-23:1. ОбаThe burning of enriched carbonaceous pyrites with co-storage of 42-45% of sulfur and 8-10% of carbon is carried out in the presence of ferrous sulfate, which is taken in relation to the carbon contained in pyrite, equal to 5-23: 1. Both

компонента ввод т в процесс раздельными потокамн в таком соотношении, что температура в реакцнонной зоне автотермически ноддерживаетс  в пределах 700-800°С. Процесс осуществл ют непрерывно в аппарате псевдоожиженного сло  или других аппаратах.the component is introduced into the process by separate streams in such a ratio that the temperature in the reaction zone is autothermally maintained within 700-800 ° C. The process is carried out continuously in a fluid bed apparatus or other apparatus.

Пример. Углистый колчедан, содержащий 45% серы и 8,3% углерода, подают в онытную нечь псевдоожнжен.ного сло  в количестве 10 кг/час. Одновременно в печь ввод т 15 кг/час высушенного сульфата железа. Отношение вводимого сульфата к углероду, содержанлемус  в углнстом колчедане, составл ет 18:1. Температуру в реакцнонной зоне автотермнчески поддерживают в нределах 700-720°С. Получают газ следующего состава (в %): SOa 8,45; COg 4,55; Ol 10,80.Example. Coaly pyrites, containing 45% of sulfur and 8.3% of carbon, are fed into the test bed of a fluidized bed of 10 kg / h. At the same time, 15 kg / h of dried ferrous sulfate was introduced into the furnace. The ratio of sulfate added to carbon contained in the pyritic carbonate is 18: 1. The temperature in the reaction zone is autothermically maintained at 700-720 ° C. A gas of the following composition is obtained (%): SOa 8.45; COg 4.55; Ol 10.80.

Предмет изобретени Subject invention

Способ переработки углистого колчедана на серннстый ангидрид путем его обогащени  н обжига, отличающийс  тем, что, с целью повышени  концентрации сернистого антидрида, обжиг ведут в присутствии сульфата железа при его весовом отношении к углероду колчедана , равном 5-23 : 1.A method of processing carbonaceous pyrite to sulfuric anhydride by enriching it and burning it, characterized in that, in order to increase the concentration of sulfurous antidride, roasting is carried out in the presence of ferrous sulfate with its weight ratio to pyrite carbon equal to 5-23: 1.
