METHANOL TREATMENT OF ALUMINOSILICATE-CONTAINING ATAE CLEAVAGE CATALYSTS

摘要

The invention relates to a process for producing an aluminosilicate catalyst intended for use in the cleaving of alkyl tert-alkyl ethers (ATAE) to olefins and alcohols. It is based on the problem of specifying a process for producing an acidic heterogeneous catalyst which features reduced initial activity in ATAE cleavage. The problem is solved by treating the catalyst with methanol before using it in the ATAE cleavage.
