В российских компаундированных автобензинах  содержание бензинов каталитического крекинга (БКК) превышает 30 %, при этом большая часть серы из разрешённых по стандарту Евро-5 десяти ppm поступает в товарные бензины именно с БКК. Высокое содержание серы в БКК делает невозможным их использование без предварительной гидроочистки, неизбежно снижающей октановое число бензинов. Рассмотрена природа серосодержащих соединений и соединений, вносящих основной вклад в октановое число. Проведен обзор современных технологических процессов и катализаторов гидроочистки БКК. Показано, что современные процессы обессеривания бензинов основаны на предварительном фракционировании и раздельной очистке тяжелой и лёгкой фракций,  что делает их технологически сложными и энергоемкими. Институтом катализа им. Г.К. Борескова СО РАН совместно с АО "Газпромнефть-МНПЗ" разработаны катализатор и процесс селективной одностадийной гидроочистки БКК. Разработанный катализатор позволяет проводить селективную гидроочистку всей фракции БКК без предварительного фракционирования с получением бензина с содержанием серы не более 10 ppm и падением октанового числа не более чем на 1 пункт. 

Content of catalytic cracking gasoline (GCC) in Russian blended gasoline is greater than 30 %. The most of sulfur in blended gasoline comes from GCC, while permitted sulfur content in commercial gasoline of Euro 5 standard is 10 ppm. High sulfur content of the GCC makes it impossible to use them without prior hydrotreating, inevitably reducing the octane number of gasoline. The nature of sulfur compounds that make the major contribution to the octane number was considered. An overview of modern technological processes and catalysts for hydrotreating of GCC was made. It was shown that modern gasoline desulfurization were based on pre-fractionation and separate purification of heavy and light fractions that made them technologically complicated and energy-intensive. Boreskov Institute of Catalysis together with AO “Gazpromneft-MNPZ” developed the catalyst and a single stage hydrotreating process of GCC. Developed catalyst provides selective hydrotreating of all GCC fractions without prefractionation to obtain gasoline with a sulfur content of no more than 10 ppm, and octane number loss not more than 1 point.
