"OLIGOMERIZAçãO DE OLEFINAS". A presente invenção refere-se a uma peneira molecular selecionada, que ZSM-22 ou ZSM-23, por exemplo, é usada como catalisador de oligomerização de olefinas para resultar em um produto, octenos e dodecenos, por exemplo, a partir de buteno, tendo um baixo grau de ramificação e de ligações duplas impedidas. A selectivated molecular sieve, e.g., ZSM-22 or ZSM-23, is used as olefin oligomerization catalyst to provide product, e.g., octenes and dodecenes from butene, having a low degree of branching and hindered double bonds.
