Abstract

Fourier transform ion cyclotron resonance mass spectrometry is applied to identify adsorbed species formed from ethene in zeolite HMFI. Long chain alkenes (up to 18 carbon atoms) are detected from the zeolite exposed to ethene at 298 K from vacuum desorption, laser induced desorption and laser ablation-chemical ionization experiments. Reaction with ethene at 420 K forms a mixture of linear alkenes, branched alkanes, and some mononuclear aromatics. After reaction at 560 K, the major adsorbed species are alkylbenzenes and alkylnaphthalenes. (C) 1998 Elsevier Science B.V. All rights reserved.
