DEALUMINIZED CATALYST CARRIER, METHOD FOR PRODUCING SAID CATALYST CARRIER AND METHOD FOR HYDRATING C2 OR C3 OLEFINS WITH WATER IN THE PRESENCE OF A CATALYST CONSISTING OF SAID ACID-SATURATED CATALYST CARRIER

摘要

The invention relates to a dealuminized catalyst carrier, a method for producing a catalyst carrier having a lower aluminium content on the basis o f naturally occurring sheet silicates, such as montmorillonite, and to a metho d for hydrating C2 or C3 olefins which uses the catalyst carrier having a lowe r aluminium content. For the acid-catalyzed hydration reaction the carrier is saturated with phosphoric acid. The improvement the invention provides for i n comparison with known hydration methods is characterized in that the carrier is no longer subject to aluminium leaching in the presence of the phosphoric acid. As a result, there is no further risk of aluminium phosphate blockages occurring in apparatus positioned downstream of the reaction.
