The invention relates to a novel catalyst based on zeolite, the production of that catalyst, and the use of the catalyst in a method for producing lower olefins from oxygenates and for oligomerizing olefins. The novel catalyst has a SiO/AlOweight ratio of 2 to 9, a BET surface of 250 to 500 m/g, and an Na content under 200 ppm. The catalyst includes a crystalline alumosilicate zeolite and a binder. The catalyst is characterized in that the ratio of the peak heights of its IR absorption bands v=3610 cm&#xb1;20 cm/v=3680 cm&#xb1;20 cmis greater than 1.8.

Ring opening process

The present invention relates to a catalyst composition for the reaction of hydrocarbons comprising a zeolite with has a faujasite structure and a fibrous zeolite which comprises essentially non-crossing one-dimensional channels. Further, the catalyst composition comprises in a preferred embodiment a metal component selected from metals of the group VIB and VIII of the periodic table of elements and their compounds. The invention relates further to a process for the synthesis of such a catalyst composition and to a process for hydrocracking hydrocarbon feedstocks by using said catalyst composition.

A process is described for producing synthetic zeolites useful as catalysts with a MFI structure, a Si/Al atomic ratio from about 8 to 45 to 1 and very small primary crystallites. A Si source, an Al source and an organic template are reacted with one another under hydrothermal conditions. The process is carried out in the presence of seed crystals with an average particle size from roughly 10 to 100 nm, preferably from 20 to 50 nm, prepared from an earlier batch of synthetic zeolites with a MFI structure, without separation from the mother liquor. The process further includes conversion by ion exchange of the zeolites into an H form. Moldings may also be produced by the addition of binders and optionally catalytically active base metal and/or precious metal components before or after the moldings are produced. The zeolites as claimed in the invention are characterized by the combination of the following features:
