| Summary: | Заглавие с экрана С применением метода математического моделирования исследовано влияние давления в реакторах на выход и качество продукта промышленной установки риформинга бензиновых фракций. Установлено, что работа на пониженном давлении позволит увеличить выход продукта на 2% масс., а также будет способствовать повышению выхода водорода и ароматики, но при этом будет увеличиваться скорость коксонакопления на катализаторе. С использованием математической модели проанализирован процесс риформинга на двух катализаторах: PR-9 и PR-81. Показано, что платино-рениевый катализатор сохраняет высокую активность, стабильность и селективность в течение всего рабочего цикла. Catalytic naphtha reforming is a very important and effective process for petrochemical industry due to the octane improvement and aromatic feedstocks production. A large number of reactions occur in catalytic reforming, such as dehydrogenation, dehydroisomerization, hydrocracking, isomerization, dehydrocyclization. The catalytic naphtha reforming process yield and its quality depends strongly on the catalytic properties. The catalyst undergoes physiochemical changes during operation what contribute to decrease its activity and selectivity. Coke formation process is the most important catalyst deactivation cause. Coke formation prediction is a quite complex task, because this process depends on operating conditions, oil feed composition, catalyst properties. Operating conditions strongly affect the catalyst. The strategy of reforming technology improving goes hand in hand with a pressure reduction. The aim of this study is analysis of pressure effect on the product yield and its quality in industrial catalytic reforming unit by mathematical modelling method. Industrial catalytic reforming unit with a preliminary hydro-treating in Russia was used as an object. The performance analysis of the reforming catalyst PR-9 and operation prediction on the catalyst PR-81 for production reforming unit have been carried out using a mathematical model. With the computer modelling system using the effect of pressure on the quality of the product has been carried out. It was proved that the work at reduced pressure will increase the product yield by 2% mass, and also will enhance the yield of hydrogen and aromatic hydrocarbons. But, with the pressure reduction the rate of coke formation will increase, so the pressure is not recommended to drop below 1.4 MPa. Режим доступа: по договору с организацией-держателем ресурса |
