Transformations of stable gas condensate hydrocarbons into high-octane gasoline components over ZSM-5 zeolite catalyst

The process of stable gas condensate zeoforming was implemented at the laboratory scale under the conditions of varying feedstock composition and technological parameters (temperature, pressure, feedstock flow rate). The directions of hydrocarbon transformations were established. The influence of technological parameters on the composition and properties of the obtained product was estimated. From the perspective of involving the obtained zeoforming product into production of motor gasoline, optimal technological parameters were determined (the temperature of 375 °C, the pressure of 2.5 MPa, the feedstock flow rate of 2 h⁻¹), the most preferred feedstock was established (the feedstock, which contains high amount of naphthenes, which sufficiently influence aromatization reaction). The recipes for motor gasoline blending were developed using the zeoforming product as the major component for the production of different grades, such as RON-92, RON-95, RON-98, meeting the modern specifications.
