Abstract: The present invention (in a first embodiment) relates to a process for the dehydration of an alcohol having at least 2 carbon atoms to make the corresponding olefin, comprising: introducing in a reactor a stream (A) comprising at least an alcohol, optionally water, optionally an inert component, contacting said stream with a catalyst in said reactor at conditions effective to dehydrate at least a portion of the alcohol to make an olefin, recovering from said reactor an olefin containing stream (B), Wherein, the catalyst is a crystalline silicate of the group FER, MWW, EUO, MFS, ZSM-48, MIT or TON having Si/Al under 100, or a dealuminated crystalline silicate of the group FER, MWW, EUO, MFS, ZSM-48, MTT or TON having Si/Al under 100, or a phosphorus modified crystalline silicate of the group FER, MWW, EUO, MFS, ZSM-48, MTT or TON having Si/Al under 100, the WHSV of the alcohol is at least 4 h?1 and/or the temperature ranges from 320° C. to 600° C.
