A model compound is used to probe the chemical and physical behaviors of asphaltene. Hydrogenation reactions were conducted in a batch microreactor at 430℃, 13.9 MPa H2 for 30 min using a solution of 1,3,6,8-tetrahexylpyrene in tetralin. Sulfided iron was prepared on α-alumina, γ-alumina and glass beads as support materials. The hypothesis of this study was that addition reactions can be suppressed under hydrogenation conditions by using sulfided iron as a low active catalyst by saturating olefin intermediates. The products were analyzed by high performance liquid chromatography, gas chromatography and matrix assisted laser desorption ionization mass spectrometry to investigate conversion and product distribution for different catalysts. The results show that catalyst can give significant suppression of addition reactions from 63 mol % for non-catalytic to 13 mol % for sulfided Fe/α-Al2O3 and shift the selectivity toward cracking, without giving a high level of hydrogenation of the aromatics.
