    • The present invention relates, in a first embodiment, to the use of a catalyst to convert at least an alcohol into light olefins in a dehydration process to make an olefin having the same number of carbon atoms as the alcohol wherein said catalyst comprises a phosphorus modified zeolite and is made by a method comprising the following steps in this order, a) providing a zeolite comprising at least one ten members ring in the structure, optionally steaming said zeolite, b) mixing said zeolite of step a) with at least a component selected among one or more binders and shaping additives, then shaping said mixture, c) optionally making a ion-exchange, d) optionally steaming the shaped catalyst, optionally before step c), at least among said steaming of step d) and the steaming of step a) one is mandatory, e) introducing phosphorus on the catalyst to introduce at least 0.1 wt% of phosphorus, said introduction being made by dry impregnation or chemical vapor deposition, f) optionally introducing a metal, optionally simultaneously with step e), g) optionally washing the catalyst, h) optionally calcinating the catalyst, i) steaming the catalyst, also referred to as the equilibration step. In a second embodiment phosphorus can be introduced by any means and at step i) the steaming severity (X) is at least about 2. In said second embodiment the catalyst is advantageously steamed at a temperature above 625°C, preferably in the range 700 to 800°C. The metal of step f) is advantageously Calcium.
