摘要： A process for the dehydration of an alcohol having at least 2 carbon atoms to make a corresponding olefin may include introducing in a reactor a stream (A) containing the alcohol, optionally water, and optionally an inert component. The stream (A) may be contacted with a catalyst in the reactor at conditions effective to dehydrate at least a portion of the alcohol to make the corresponding olefin. The process includes recovering from the reactor an olefin containing stream (B). The catalyst may be a crystalline silicate, dealuminated crystalline silicate, or phosphorus modified crystalline silicate, each of the group FER, MWW, EUO, MFS, ZSM-48, MTT or TON having Si/Al ranging from 25 to 90. The weight hourly space velocity (WHSV) of the alcohol may be at least 4 h−1. The temperature may range from 280° C. to 600° C., or from 320° C. to 600° C.
