The present invention relates to an active and selective zeolite catalyst having MTT structure that is useful in skeletal isomerisation of light olefins. The method for the manufacture of the zeolite catalyst having MTT structure comprises the steps of a) preparing of a gel mixture capable of forming crystalline material, and the mixture comprising sources of alkali or alkaline earth metal (M), of an oxide of a trivalent element (X), of an oxide of a tetravalent element (Y), water and a directing agent (R), and the mixture having a composition, in terms of molar ratios, within the given ranges; b) maintaining the mixture under sufficient conditions, including a temperature of from about 100&#xb0; C. to about 250&#xb0; C., under dynamic mode of stirring until crystals of the material are formed, recovering the material; and c) removing the directing agent (R) partly or totally with a calcination procedure.
