Abstract: A process for the preparation of lower olefins from methanol or dimethyl ether by catalytic conversion at from 300.degree. to 550.degree. C. in two stages over borosilicate zeolites, wherein C.sub.2 -C.sub.4 -olefins and C.sub.1 -C.sub.4 -paraffins are removed after the first reaction stage, the C.sub.5.sup.+ hydrocarbons are passed to the second reaction stage, the aromatics are removed from the reaction product of the second stage and the remaining reaction products are recycled. The advantage of this process is an improvement in the yield of olefins.

Abstract: Alkali metal beryllo-alumino-silicates of the mordenite type form, under hydrothermal conditions (100.degree.-300.degree. C in a Carius tube), from aqueous mixtures containing the structural components SiO.sub.2, Al.sub.2 O.sub.3 and BeO and alkali metal hydroxides. In beryllium-containing mordenites, ratios of SiO.sub.2 to Al.sub.2 O.sub.3 of from 10:1 to 120:1 may be achieved, whereas values of only up to 10:1 are known in the pure alumino-silicates of this type. The alkali metal beryllo-alumino-silicates are accessible to ion exchange in the same way as the beryllium-free representatives. The so-called NH.sub.4 - and H-forms obtaineable by ion exchange may be used for the synthesis of highly active sorption compositions or catalysts after calcination.
