Изобретение относитс к области получени битумов, используемых в качестве строительного материала.This invention relates to the field of bitumen used as a building material.
Известны способы получени битумов окислением гудрона, смеси переокисленного крекинг-остатка , а также т желой пиролизной смолы. Окисление осуществл ют при высокой температуре (280-250°С).Methods are known for producing bitumens by oxidation of tar, a mixture of over-oxidized cracking residue, as well as a heavy pyrolysis resin. The oxidation is carried out at a high temperature (280-250 ° C).
Известен также способ получени битума окислением экстракта селективной очистки масел I.There is also known a method for producing bitumen by oxidizing an extract of selective purification of oils I.
Недостатком способа вл етс проведение процесса при высоких температурах - 250- 300°С и продолжительном времени-13- 14 час. Битумы, полученные указанным способом , не могут быть использованы в дорожном строительстве, из-за высокой температуры хрупкости, низкой пенетрации и раст жимости .The disadvantage of this method is to carry out the process at high temperatures of 250-300 ° C and a long time of 13-14 hours. Bitumens obtained by this method cannot be used in road construction, due to the high temperature of brittleness, low penetration and extensibility.
С целью повышени эффективности и упрощени процесса по предлагаемому способуIn order to increase efficiency and simplify the process of the proposed method
окисление осуществл ют в присутствии 3- 5 вес. % сажи при 180-200°С в течение 90- 210 мин.The oxidation is carried out in the presence of 3-5 weight. % carbon black at 180–200 ° C for 90– 210 min.
Желательным вл етс использование в качестве исходного сырь экстрактов селективной или адсорбционной очистки масел.It is desirable to use selective or adsorptive oil purification extracts as feedstock.
Пример. Экстракт селективной или адсорбционной очистки минеральных масел окисл ют в присутствии 3 вес. % сажи при температуре 180-200°С с подачей воздуха 0,5-0,6 атм.Example. The extract for selective or adsorption purification of mineral oils is oxidized in the presence of 3 wt. % of carbon black at a temperature of 180-200 ° C with an air supply of 0.5-0.6 atm.
Процесс окислени длитс от 1 час 30 мин, до 2 час 30 мин в зависимости от требуемой марки битумов.The oxidation process lasts from 1 hour 30 minutes to 2 hours and 30 minutes depending on the desired grade of bitumen.
Ниже приведены сравнительные показатели битумов, полученных различными способами.Below are comparative indicators of bitumen obtained in various ways.
Предлагаемый способ дает возможность получать высококачественные битумы на основе экстракта селективной очистки смазочных масел (остатков) с использованием оборудовани битумоварочных заводов.The proposed method makes it possible to obtain high-quality bitumens based on an extract for the selective purification of lubricating oils (residues) using equipment of bitumen processing plants.
