Description

Изобретение относится к способам извлечения марганцевого катализатора из сточных вод, содержащих органические и минеральные вещества, например шламовых сточных вод, которые образуются в производстве синтетических жирных кислот на стадии окисления парафиновых углеводородов.The invention relates to methods for extracting manganese catalyst from wastewater containing organic and mineral substances, such as sludge wastewater, which are formed in the production of synthetic fatty acids at the stage of oxidation of paraffinic hydrocarbons.

Известен способ извлечения марганцевого катализатора из шламовых вод производства синтетических жирных кислот путем обработки шламовой воды кальцинированной содой с последующим отделением образовавшегося при этом осадка углекислого марганца, смешением его с маточным раствором натриевых солей жирных кислот до получения соотношения Мп : Ца = = 1:0,42 и обработкой последовательно серной кислотой и щелочью [1].There is a method of extracting manganese catalyst from sludge water production of synthetic fatty acids by treating sludge water with soda ash, followed by separating the resulting manganese carbonate precipitate, mixing it with the mother liquor of sodium salts of fatty acids to obtain the ratio MP: Ca = 1: 0.42 and processing successively with sulfuric acid and alkali [1].

К предлагаемому способу наиболее близок способ извлечения марганца из шламовых вод производства синтетических жирных кислот путем обработки шламовой воды, образовавшейся на стадии окисления парафинов, щелочными агентами, например кальцинированной содой. В результате соединения марганца в виде смеси карбоната с его гидроокисью выпадают в осадок. Осадок — катализаторный шлам подвергают термической обработке при 400—600°С,The proposed method is closest to the method of extracting manganese from the sludge water production of synthetic fatty acids by treating the sludge water formed at the stage of oxidation of paraffins, alkaline agents, such as soda ash. As a result, manganese compounds in the form of a mixture of carbonate with its hydroxide precipitate. Sediment - catalyst sludge is subjected to heat treatment at 400-600 ° C,

в процессе которой получают порошкообразный продукт с содержанием окислов марганца более 40%. Из этого порошка окислы марганца могут быть извлеченыduring which a powdered product is obtained with a manganese oxide content of more than 40%. Manganese oxides can be extracted from this powder.

5 известным способом, например флотацией и пр. [2].5 in a known manner, for example by flotation, etc. [2].

Claims (1)

Указанный способ позволяет лишь частично исключить химические реагенты, например серную кислоту, которая используется для получения сульфата марганца, но не исключает затрат на расход щелочных агентов, например кальцинированной соды, применяемой для осаждения соединений марганца в виде катализаторного шлама из шламовой воды. Кроме того, сохранение стадии нейтрализации в процессе регенерации катализатора оставляет нерешенной про'блему очистки шламовых вод — одного из наиболее загрязненных органическими веществами потока сточных вод, так как нейтрализация последних кальцинированной содой позволяет снизить содержание органических веществ лишь на 20— 30%.This method allows only partially eliminate chemical reagents, such as sulfuric acid, which is used to obtain manganese sulphate, but does not exclude the cost of the consumption of alkaline agents, such as soda ash, used to precipitate manganese compounds in the form of catalyst sludge from sludge water. In addition, the preservation of the neutralization stage in the process of catalyst regeneration leaves unresolved the problem of purification of sludge water - one of the sewage streams most polluted with organic substances, since neutralization of the latter with soda ash reduces the organic content by only 20-30%. Целью изобретения является упрощение способа и снижение загрязнения сточных вод.The aim of the invention is to simplify the method and reduce pollution of wastewater. Цель достигается тем, что термической обработке подвергают шламовую воду,The goal is achieved by the fact that heat treatment is subjected to slurry water,
