Description
Изобретение относитс к электродной промышленности и может быть использовано при получении св зующего (например, пека) дл углеграфитовых изделий путем термической переработки жидких углеводородов, обогащенных ароматикой.The invention relates to the electrode industry and can be used in the preparation of a binder (for example, pitch) for carbon and graphite products by thermal processing of liquid hydrocarbons enriched with aromatics.
Известный способ переработки жидких углеводородов не позвол ет получать продукты с заданными качествами.The known method of processing liquid hydrocarbons does not allow to obtain products with desired qualities.
С целью получени продуктов заданного качества, предлагаетс в поток инертных газов , имеющих температуру 1300-2500°С, вводить жидкие углеводороды, например необработанную нефть, с содержанием ароматики не менее 80%. Процесс ведут при времени реакции 0,001-0,1 сек, температуре 900- 1500°С и давлении 0,4-200 кг/см. Изменением параметров реакции регулируют свойства получаемых продуктов.In order to obtain products of a given quality, it is proposed to introduce liquid hydrocarbons, such as crude oil, with an aromatic content of at least 80%, into the stream of inert gases having a temperature of 1300-2500 ° C. The process is carried out at a reaction time of 0.001-0.1 seconds, a temperature of 900-100 ° C and a pressure of 0.4-200 kg / cm. Changes in the parameters of the reaction regulate the properties of the products obtained.
Пример 1. В поток инертных газов, имеющих температуру 1750°С, ввод т сырую нефть, содержащую не менее 98% ароматики и имеющую отнощение Н/С, равное 0,96, со скоростью 20 кг/час. Врем реакции составл ет 0,008 сек 1при давле:нии 3 кг/см и. температуре 1150°С.Example 1. Into an inert gas stream having a temperature of 1750 ° C, crude oil containing not less than 98% of aromatics and having an H / C ratio of 0.96 is introduced at a rate of 20 kg / h. The reaction time is 0.008 sec. At a pressure of 3 kg / cm and. temperature of 1150 ° C.
