Изобретение относитс к способам получени битума и может быть использовано в нефтеперерабатывающей промышленности.The invention relates to methods for producing bitumen and can be used in the petroleum refining industry.
Известен способ получени битума путем его модификации полиэфирами малеиновой и акриловой кислоты Ст.A known method for producing bitumen by modifying it with polyethers of maleic and acrylic acid Art.
Наиболее близким к предлагаемому изобретению вл етс способ получени битума путем обработки нефт ных гудронов перекис ми или гидроперекис ми органических и (или) неорганических соединений при 200-300 С и давлении до 20 атм в течение ч в присутствии кислорода воздуха 2.The closest to the proposed invention is a method for producing bitumen by treating petroleum tars with peroxides or hydroperoxides of organic and / or inorganic compounds at 200-300 ° C and pressure up to 20 atm for hours in the presence of air oxygen 2.
Однако известный способ имеет сложную технологию и получаемый битум обладает недостаточно высоким качеством,, например прочнЬстью при разрыве.However, the known method has a complex technology and the resulting bitumen does not have a sufficiently high quality, for example, strength at break.
Цель изобретени - упрощение технологии получени битума и повышение качества целевого продукта.The purpose of the invention is to simplify the technology of obtaining bitumen and improve the quality of the target product.
Поставленна цель достигаетс способом получени битума путем обработки нефт ного гудрона 2,.5 вес.% счита на исходное сырье, перекисью или гидроперекисью органических соединений , предварительно смешанной с насыщенными полиэфирами на основе акрилатов и малеатов в соотношении (2-2,5): (3-.5) вз тых в количестве 7,,1 вес.%, счита на исходное This goal is achieved by the method of obtaining bitumen by treating petroleum tar 2, .5 wt.% Based on the feedstock, with peroxide or hydroperoxide of organic compounds, previously mixed with saturated polyesters based on acrylates and maleates in a ratio of (2-2.5): ( 3-.5) taken in an amount of 7,, 1 wt.%, Based on the original
10 сырье, при атмосферном давлении,температуре 105-200°С в течение 20120 мин.10 raw materials, at atmospheric pressure, temperature 105-200 ° С for 20120 minutes.
Способ осуществл ют следующим об5 разом.The method is carried out as follows.
Пример. Провод т 8 опытов. В смеситель, снабженный пропеллерной, или лопастной мешалкой, ввод т гудрон , нагревают его при 105 200С,Example. Conducted 8 experiments. Tar is introduced into the mixer equipped with a propeller or paddle stirrer, heated at 105 ° C.
