A dehydration process may include introducing in a reactor an alcohol, and contacting the alcohol with an acidic catalyst to dehydrate the alcohol to make a corresponding olefin. The process may include recovering from the reactor the olefin and water. In the process, an effective amount of a component capable to neutralize a part of the catalyst active site may be introduced. The component may include ammonia, organic ammonium salts, hydrazine, nitriles, amines, amides, imines, di-imines, imides, cyanates, isocyanates, nitrites and nitroso compounds, aldehydes, ketones, carboxylic esters, and their corresponding thio-compounds.
