Abstract

Способ многоступенчатого дегидрирования, включающий контактирование на первой ступени потока исходного материала, содержащего углеводород и пар, с катализатором дегидрирования в условиях дегидрирования с получением выходящего потока первой ступени, нагревание выходящего потока первой ступени и контактирование на второй ступени нагретого выходящего потока первой ступени с катализатором дегидрирования в условиях дегидрирования с получением выходящего потока второй ступени, содержащего продукт дегидрирования, причем первая ступень содержит первый реактор и второй реактор, расположенные параллельно, и при этом вторая ступень содержит третий реактор, соединенный последовательно с первым реактором и вторым реактором. Также предложена система многоступенчатого дегидрирования для осуществления дегидрирования.
