Abstract
There is provided a catalyst comprising from 0.5 to 7% by weight of trifluoromethanesulfonic acid incorporated onto an acid-form pentasil zeolite having a Si/Al atomic ratio ranging from 5 to 50 and a process for producing same. Also within the scope of the present invention is a process for the conversion of dilute aqueous ethanol to ethylene comprising: flowing said ethanol through a catalyst comprising from 0.5 to 7% by weight of trifluoromethanesulfonic acid incorporated onto an acid-form pentasil zeolite having a Si/Al atomic ratio range from 5 to 50 at a temperature ranging from 170.degree. to 225.degree. C. and recovering the desired product.
