  • Patent number: 4623526
    Abstract: A new crystalline titanoborosilicate comprises a molecular sieve material having the following composition in terms of mole ratios of oxide:0.9.+-.0.2M.sub.2/n O: aTiO.sub.2 :bB.sub.2 O.sub.3 : ySiO.sub.2.zH.sub.2 Owherein M is at least one cation having a valence n, a is greater than zero but less than 1, b is greater than zero but less than 1 such that a+b=1, y is a value within the range of 8 to about 500, and z is a value within the range of 0 to about 100 and giving a specific X-ray diffraction pattern. The crystalline titanoborosilicate is used to catalyze various processes such as conversion of simple alcohols into liquid hydrocarbons having boiling points within the gasoline boiling range, aromatization, and alkylation. A process of preparing the new crystalline titanoborosilicate is also disclosed.
    Type: Grant
