ABSTRACT:
The present invention relates to a catalyst and its use in a process for the conversion of ethene to a product rich in linear butenes, especially 2-butene, comprising contacting a feedstock comprising ethene under dimerization conditions with a catalyst composition comprising a porous crystalline silicate having the structure of ZSM-35 which has been treated by a) fluoriding, e.g., with NH.sub.4 F, and then b) at least partially surface deactivated for acid catalyzed reactions by chemisorption of a surface-deactivating agent which possesses an average cross section diameter greater than that of the zeolite pores, e.g., collidine.
