Description
бестоимость на 2-4 руб. за 1 т и ниже в зкость (см. таблицу). Пример. Газойлевую фракцию, вылипающую в пределах 250-5ОО°С, полученнуюThe cost of 2-4 rubles. 1 t and below viscosity (see table). Example. Gas oil fraction, discharging within 250-5OO ° C, obtained
при термическом крекинге смеси экстракта селективной очистки масел и газойл коксовани , подвергают деалкилированию на пилотной установке. Процесс деалкилировани ведут при температуре 565°С, давлении 30 кг/см и времени реакции 1,5 мин. Из продуктов используют в качестве сырь дл активных и высокоструктурных саж фракцию 20О-500°С. Выход ее составл ет 78%, а в пеоесчете на сырье термокрекинга - 4О%.during thermal cracking of a mixture of an extract of selective purification of oils and gas oil coking, is subjected to dealkylation on a pilot plant. The dealkylation process is carried out at a temperature of 565 ° C, a pressure of 30 kg / cm and a reaction time of 1.5 minutes. Of the products used in the raw material for active and highly structural carbon blacks is a fraction of 20–500 ° C. Its yield is 78%, and in terms of thermal cracking feedstock it is 4%.
