Abstract
Olefin oligomerization employing as a catalyst PA1 (a) a ferrierite of the following approximate formula: EQU M.sub.x/n (T.sup.III O.sub.2).sub.x (Si.sup.IV O.sub.2).sub.36-x PA1 where PA2 T.sup.III represents at least one element selected from the group of boron (B.sup.III), aluminum (Al.sup.III), gallium (Ga.sup.III) and iron (Fe.sup.III); PA2 x ranges from 0.05 to 6.6; PA2 M is a compensation cation; and PA2 n is the valence of M; PA1 (b) an X-ray diffraction diagram shown in Table 1 of the description; PA1 (c) a fluorine content after synthesis ranging from about 0.01 to 1.6% by weight; and PA1 (d) a Si.sup.IV /T.sup.III molar ratio of at least about 4.75.
