Abstract
A process for oligomerization of an olefinic feedstock that contains olefinic hydrocarbon molecules that have 2 to 10 carbon atoms per molecule is described, whereby said process comprises bringing said feedstock into contact with a catalyst that comprises at least one amorphous material with hierarchized and organized porosity and consists of at least two elementary spherical particles, each of said particles comprising a mesostructured silicon-oxide-based matrix that has a mesopore diameter of between 1.5 and 30 nm and that exhibits amorphous and microporous walls with a thickness of between 1 and 50 nm, whereby said elementary spherical particles have a maximum diameter of 200 microns.
