Abstract

Molybdenum based sulfide catalysts are widely used in hydroprocessing of petroleum fractions in refining industry. Multi-probe molecular reactions for simultaneous HDS, HDN, and C-C hydrogenolysis over Mo-based monometallic and bimetallic carbide and sulfide catalysts, in conjunction with the work on single-probe molecular reactions were presented. A multi-component model-feedstock was used to test catalytic functions. These reactions were precisely those involved in the conversion and processing of heavy hydrocarbon resources such as heavy oil, coal, and other residual materials. The multi-component feed includes 4-(1-naphthylmethyl)bibenzyl, dibenzothiophene, quinoline, pyrene, and eicosane. ATTM and Co-Mo/Al2O3 and Ni-Mo/Al2O3 showed high activity on hydrogenolysis and hydrogenation properties. Mo2C exhibited low activity on the model compounds, indicating Mo2C was strongly affected by the existence of other co-reactants. ATTM performed as a better catalyst precursor on HDN than even the commercial Co-Mo/Al2O3 and Ni-Mo/Al2O3 catalysts.
