A catalyst for converting dimethyl ether into light olefins, including ethylene and propylene. The catalyst comprises a mixture of two zeolites, ZSM-5 and ZSM-35, intimately mixed and kept in close proximity in a porous extruded binder system. The resulting combination of zeolites demonstrates a synergistic effect with respect to the conversion of the dimethyl ether and has improved resistance to deactivation due to carbon and coke formation than the individual zeolites alone when operating in this reaction. The catalyst is used to produce ethylene and propylene from a feed mixture containing methanol, dimethyl ether and water.

A process for the production of middle distillates comprising at least one hydrocracking stage that oligomerizes a paraffinic feedstock produced by Fischer-Tropsch synthesis, the process using a catalyst that comprises at least one hydrogenating-dehydrogenating metal that is selected from the group that is formed by the metals of group VIB and group VIII of the periodic table, by themselves or in a mixture, and a substrate that comprises a beta zeolite in the form of crystallites with a mean size that is less than 100 nm dispersed in at least one porous mineral matrix, whereby the beta zeolite has a mesopore volume of less than 0.4 ml/g.
