Dealuminized catalyst support, method for producing said catalyst support and method for hydrating C2- or C3-olefins with water in the presence of a catalyst consisting of this catalyst support impregnated with acid

摘要

What is claimed is a dealuminated catalyst carrier, a process for producing a catalyst carrier with reduced aluminium content based on naturally occurring lattice-layer silicates, such as, for example, montmorillonite, as well as a process for the hydration reaction of C₂- or C₃-olefins in which said catalyst carrier with reduced aluminium content is used. For acid-catalysed hydration reaction the catalyst carrier is impregnated with phosphoric acid. The improvements according to the invention of the hydration reaction compared to conventional processes include the fact that no aluminium is leached out of the carrier in the presence of the phosphoric acid. As a result no more blockage of the succeeding apparatus due to aluminum phosphate is expected.
