The Transformation of n-nonane in Conditions of Catalytic Cracking on ZSM-5 and V2O5/ZSM-5 Catalysts

Authors: Osipova K. A., Senatov D. S., Ohrimenko V. A., Aniskova Т. V.

The daily increasing demand for high-quality motor fuels requires constant improvement and modernization of existing technologies for oil refining. One of the main secondary processes of recycling hydrocarbon raw materials in industry, which allows to obtain high-octane components of automobile gasoline, valuable liquefied gases and raw materials for petrochemical industries is catalytic cracking of various types of distillate and residual raw materials. Nowadays, most catalysts of an industrial catalytic cracking contain expensive rare earth elements and platinum in its composition.

Modelling of Drying Process of Natural Gas at a Pressure of 20–25 MPa through Aluminogel and NaA 4A Zeolite

Authors: Nikiforov I. A., Krivonosov A. A.

Containment of water vapor in natural gas prevents its transportation and applying as an internal combustion fuel. The most demanded drying technology is adsorption at high pressure. The construction of a mathematical model for predicting the process is a significant task. Through a mathematical model of the process of water adsorption from natural gas at pressures of 20–25 MPa and temperatures of 5–40°C in the presence of NaA 4A zeolite and aluminogel, commonly used dehumidifier, optimal drying conditions were selected.

Превращения н-гексана и стабильного гидрогенизата на поверхности высокомодульных цеолитных систем

Authors: Kuzmina R. I., Игнатьев С. В.

Исследованы превращения н-гексана и стабильного гидрогенизата (температура кипения 85–180 °С) в интервале температур 250–500 °С. Установлено, что процесс превращения н-гексана включает в себя реакции крекинга, изомеризации и ароматизации. Направление химических превращений зависит от параметров активации и условий протекания процесса. Конверсия стабильного гидрогенизата позволяет получать высокооктановые компоненты топлива.
