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 Cand Colefins to produce Cand Calcohols. A method for the production of the catalyst support and a process for hydrating Cand Colefins are also described. One advantage of this catalyst support is the reduction in aluminum leaching that occurs when this catalyst is used in the presence of phosphoric acid.

Dealuminized catalyst carrier, method of production, and method for hydrating C2 or C3 olefins with water

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- or C-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 aluminium phosphate is expected.

Disclosed is a method for the preparation of cumene by reacting isopropanol or a mixture of isopropanol and propene with benzene in the presence of a &#x3b2;-zeolite catalyst having a SiO/AlOmolar ratio greater than 10:1 that can be integrated in a process for preparing phenol, which comprises preparing cumene as described above, oxidizing cumene to cumene hydroperoxide, acid-catalyzed cleavage of cumene hydroperoxide to give phenol and acetone, and hydrogenating acetone to form isopropanol.

Alkyl tert-alkyl ethers are cleaved into the corresponding isoolefins and alkanols by a process comprising acid-catalyzed reactive distilling an alkyl tert-alkyl ether fed into the reaction zone of a reactive distillation apparatus as an azeotrope of the alkyl tert-alkyl ether and the corresponding alkanol, wherein the reactive distillation apparatus is configured from bottom to top as a bottom zone, at least one distillation zone and a reaction zone. The process is suitable for the cleavage of primary, secondary and tertiary alkyl tert-alkyl ethers, in particular MTBE.

The present invention is directed to a process for the acid-catalyzed cracking of tertiary butyl alcohol in a reaction distillation column. The advantage of the process of the present invention compared with conventional processes is that the two-phase, liquid-liquid region of the tertiary system TBA/water/isobutene is avoided and a high space-time yield is achieved. This is achieved by the arrangement of the catalyst pack above the liquid phase zone (bottom) and by the use of a dephlegmator thus achieving the isolation of isobutene of high purity.
