摘要：
The granular, form-selective zeolite catalyst used as bed in a process of producing lower olefins from a feed mixture of higher olefins must be decoked from time to time. This is effected such that the reactor is rinsed with a nitrogen stream heated to 460 to 500° C. for expelling the hydrocarbons, the reactor is then cooled with a nitrogen stream heated to 420 to
