摘要： A process for making a lube base stock wherein an olefinic feedstock is separated into a light olefin fraction and a medium olefin fraction. The light olefin fraction is contacted with a first oligomerization catalyst in a first oligomerization zone to produce a first product. Both the medium olefin fraction and the first product are contacted with a second oligomerization catalyst in a second oligomerization zone to produce a second product. The second product is separated into a light byproduct fraction and a heavy product fraction that includes hydrocarbons in the lube base stock range.

摘要： A process for the catalytic conversion of hydrocarbons, in particular for the oligomerization of olefins wherein the catalyst comprises a zeolite which is at least partially in its acid form. The zeolite is a NU-86 zeolite comprising silicon and at least one element T selected from the group formed by aluminum, iron, gallium and boron, preferably aluminum, characterized in that element T has been extracted from the framework, and in that it has a global Si/T atomic ratio of more than about 20. Element T is extracted from the zeolitic framework (or network) by means of at least one heat treatment, optionally carried out in the presence of steam, followed by at least one acid attack using at least one solution of a mineral or organic acid, or by direct acid attack.
