Способ осуществления каталитического крекинга в псевдоожиженном слое состоит в использовании новой конструкции реакционного стояка, в котором образуется взвесь катализатора в разделительной зоне стояка вблизи или над впускными отверстиями циклонов для достижения плотности взвешенного катализатора, превышающей плотность катализатора в стояке. Взвешенный катализатор образует разделительную зону, которая усиливает отделение катализатора от парообразных продуктов. Работа стояка исключает какой-либо выход парообразных продуктов из его верхнего конца. Конструкция также обеспечивает удобный способ вытяжки десорбирующих паров в закрытую реакционную систему циклонов.The method of catalytic cracking in the fluidized bed is to use a new design of the reaction riser in which a catalyst slurry is formed in the separation zone of the riser near or above the cyclone inlets to achieve a suspended catalyst density greater than that of the riser. The weighted catalyst forms a separation zone that enhances the separation of the catalyst from the vaporous products. The work of the riser eliminates any release of vaporous products from its upper end. The design also provides a convenient way of extracting the stripping vapors into a closed cyclone reaction system.
