ETHYLENE DIMERIZATION ON NICKEL 4,4’-BIPYRIDINE COMPLEX SUPPORTED ON FAUJASITE TYPE ZEOLITES
Journal Title: Analele Universitatii din Bucuresti. Chimie - Year 2005, Vol 14, Issue 1
Abstract
This paper presents the activity and selectivity of a catalyst based on Ni(4,4’-bipyridine)Cl2 complex co-activated with AlCl(C2H5)2 and supported on faujasite-type zeolite Y utilised in the dimerization of ethylene at 298K in continuous flow of reactant. Chemo- and stereo-selectivity effects expressed as selectivity for dimers and oligomers, and respectively, the concentration of 1-C4H8 in C4H8 fraction and the molar ratios 2-trans-C4H8/2-cis-C4H8 are discussed. The results are correlated with the steric and diffusion hindrances induced by the microporous structure of the porous solid matrix.
