Dealuminized catalyst carrier, method of production, and method for hydrating C2 or C3 olefins w |
April 19, 2005 |
| A catalyst support comprising silicates is described. This catalyst support has a lower aluminum content than naturally occurring sheet silicates and can be used in the hydration of C.sub.2 and C.sub.3 olefins to produce C.sub.2 and C.sub.3 alcohols. A method for the production of the ca |

Method for producing a dealuminized catalyst support |
April 19, 2005 |
| What is claimed is a dealuminated catalyst carrier, a process for producing a catalyst carrier with reduced aluminum content based on naturally occurring lattice-layer silicates, such as, for example, montmorillonite, as well as a process for the hydration reaction of C.sub.2 - or C.sub. |
