PROCEDE DE CRAQUAGE D'ETHERS ALKYL TERTIAIRES UTILISANT UN MATERIAU HYBRIDE ORGANIQUE-INORGANIQUE MESOSTRUCTURE.

摘要

A process for cracking tert-alkyl ether(s) selected from among tert-amyl methyl ether (TAME) and ethyl tert-amyl ether (ETAE) for the production of tertiary olefins comprising bringing said tert-alkyl ether(s) into contact with at least one catalyst that is formed by at least one mesostructured hybrid organic-inorganic material that consists of at least two spherical elementary particles, whereby each of said spherical particles consists of a mesostructured matrix with a silicon oxide base to which are linked organic groups with acid terminal reactive functions, said groups representing less than 20 mol % of said matrix that is present in each of said spherical elementary particles, which have a maximum diameter of between 50 nm and 200 mum.
