A catalyst can be used to convert an alcohol in a dehydration process into an olefin having the same number of carbon atoms as the alcohol. The catalyst can include a phosphorus modified zeolite made by providing a zeolite with at least one ten member ring in the structure, steaming the zeolite, mixing the zeolite with binders and shaping additives, and shaping the zeolite. An ion-exchange step can be performed, and the shaped catalyst can be steamed. Phosphorus can be introduced on the catalyst at an amount of at least 0.1 wt %, such as by dry impregnation or chemical vapor deposition. A metal can be introduced. The catalyst can be washed and/or calcinated, and steamed in an equilibration step. The steaming severity (X) can be at least about 2. The catalyst can be steamed at a temperature above 625&#xb0; C., such as a temperature ranging from 700 to 800&#xb0; C.
