A crystalline encilite catalyst composite for use in the conversion of alkanols to olefins, has the composition, on an oxide molar ratio basis:
where M is a monovalent cation and Z is an integerfrom 0 to 20. The catalyst composite is prepared by reacting, in an aqueous medium, iron, silicon, an alkali metal and, if desired, sulphuric acid with a tetraalkyl ammonium saft, heating the gel obtained, removing the supernatant liquid formed by such heating, recovering the solid residue, and washing, drying and calcining the latter.
