The present Ti-A-silicalite catalyst showed the typical MFI structure, in which titanium is included in the silicalite crystalline framework. Microcrystals (0.03 to 0.05 μm) of the zeolite are stuck together to form pseudo-spherical, berry-like, strong conglomerates, approximately 0.1 to 0.5 μm in size. The catalyst proved to be more active than a similar ZSM5 sample for propylene oligomerization, which practically stops at dimers and trimers. However, the latter undergo further cleavage to C4 and C5, which in turn react with C3 to give C7 and C8 products.
