A catalyst for producing tertiary olefins from alkyl-tert-alkylethers is described, consisting of silica modified by adding alumina in a quantity of between 0.3 and 1% by weight with respect to the silica, and is prepared by a method consisting essentially of impregnating a silica with a solution of aluminium salts, followed by drying and calcining, the material then being subjected to purification treatment with aqueous acid solutions or with aqueous solutions which release acidity by thermal decomposition, followed by washing, a second drying and a second calcining.

Catalyst prepared by a particular preparation method and its use in a
