简介 PROBLEM TO BE SOLVED : To provide the use of a catalyst comprising phosphorus-modified zeolite in a dehydration process to convert an alcohol having at least 2 carbon atoms into the corresponding olefin. SOLUTION : The present invention relates to the use of a catalyst characterized by being made by a method comprising the following steps in this order : (a) the essential portion of the phosphorus is introduced into a zeolite comprising at least one ten-membered ring in the structure; (b) the phosphorus modified zeolite of the step (a) is mixed with at least a component selected among one or more binders, salts of alkali-earth metals, salts of rare-earth metals, clays and shaping additives, (b*)making a catalyst body from mixture (b); (c) an optional drying step or an optional drying step followed by a washing step is conducted; (d) a calcination step is conducted, (d*) an optional washing step followed by drying is conducted; (e) optionally a small portion of phosphorus is introduced in the course of the step (b) or (b*) or at end of the step (b) or (b*).
