Description
Предмето г изобретени способ получени фосфатных удобрений путем разложени фосфатного сырь кислым гудроном, получаемым при очистке нефтепродуктов. Кнс.тые гудроны содержат от 35 до 85% серной кие.юты, поэтому их можно с успехом примен ть д.п разложени (|)осфоритов.The subject of the invention is a method for producing phosphate fertilizers by decomposing phosphate raw materials with acidic tar obtained during the purification of petroleum products. Knight tars contain from 35 to 85% sulfuric acid, so they can be successfully used by decomposition (|) of osforites.
Чтобы нолучить удобрение, смешивают фосфорит (и.чп апатит) с гудроном, причем реакнионную массу нагревают дл расн.тавлеии гудрона . Готовый продукт получают в виде порошка.In order to get fertilizer, phosphorite (apatite) is mixed with tar, and the reaction mass is heated to dissolve tar. The finished product is obtained in powder form.
В зависимости от соотношени компонентов можно получить фосфатные удобрени с различным содержанием фосфатной кислоты. Например , если вз ть одну весовую часть гудрона на одну весовую часть фосфорита, то нолученный продукт будет содержать 3,42% РаО.-,. растворимого в воде, и 2,86% PjO-, в .чегко усво емом растени ми виде. Кроме того, iB удобрении содержитс до 30% органических соединений, у.тучшаюш ,их физические и физико-химические свойства почв.Depending on the ratio of the components, phosphate fertilizers with different contents of phosphate acid can be obtained. For example, if you take one weight part of tar per one weight part of phosphate, then the product obtained will contain 3.42% PaO- ,. soluble in water, and 2.86% PjO-, easily absorbed by plants. In addition, iB fertilizers contain up to 30% organic compounds, hardy, their physical and physicochemical properties of the soil.
Органическа часть удобрени не вли ет отрицательно на растени и ije угнетает микробиологические процессы в почве; она в почве постепенно разлагаетс . Органическую часть можно отдел ть от фосфатных удобрений, например, путем экстракции соответствующими нефт ными погонами. Полученный В результате этого суперфосфат можно обогащать усво емой п тиокисью фосфора путем вторичной обработки ее гудроном.The organic part of the fertilizer does not adversely affect the plants and ije inhibits microbiological processes in the soil; it gradually decomposes in the soil. The organic part can be separated from phosphate fertilizers, for example, by extraction with appropriate oil straps. The resulting superphosphate can be enriched with absorbable phosphorus pentoxide by secondary treatment with tar.
Большим преи.муш,еством предлагаемого способа вл етс использование серной кислоты кислых гудроиов, в значительной степени удешевл ош ,ее себестоимость фосфатных удобрений.A great advantage of the proposed method is the use of sulfuric acid, acidic Gudroi, significantly cheaper osh, its cost of phosphate fertilizers.
Предмет изобретени Subject invention
Способ получени фосфатных удобрений, отличающийс те.м, что фосфатное сырье разлагают кислым гудроном от очистки нефтепродуктов .A method for producing phosphate fertilizers, characterized in that the phosphate raw material is decomposed by refining petroleum products with acidic tar.
