Abstract
Process for the preparation of branched olefins comprising contacting a hydrocarbonaceous feedstock comprising linear olefins having at least four carbon atoms at elevated temperature with a catalyst which comprises a MeAPO and/or MeAPSO medium-pore molecular sieve having an anhydrous composition expressed in molar oxide ratios as follows; (MeO).sub.a (Al.sub.2 O.sub.3).sub.b (P.sub.2 O.sub.5).sub.c (SiO.sub.2).sub.d, whereby (a+b)/c is greater than 1.0, a ranges from 0.003 to 0.2, b and c range from 0.05 to 0.3, d is at most 0.4 and a/(c+d) is at least 0.05 when SiO.sub.2 is present, and Me is at least one of Mg, Mn, Co and Zn.
