Descripción : Energy sources form fossil fuels are the most largely used ones, and even with the development of alternative energy sources their predominance is not reducing. In addition, light crude oil reserves are depleting and the heavier ones with higher amount of impurities (S, N containing components) have to be transformed. Thus, in order to compensate this increment and fulfill quality requirements on intermediates and products highly active and selective hydrotreating catalysts have to be developed. On this matter supported and unsupported Ni(Co) W(Mo) sulphide catalysts have been largely studied. However, further research in this matter is needed to accomplish a fully understanding of their catalytic activity and performance during hydrotreating processes. This work addresses the usage of six bulk catalysts in the parallel hydrodenitrogenation (HDN) and hydrodesulfurization (HDS) reactions of the model components quinoline (Q), opropylaniline (OPA), and dibenzothiophene (DBT) as well as five supported catalyst in the hydrodearomatization (HDA) of phenanthrene (Phe). The unsupported catalyst were tested in order to study the influence of DBT in Q/OPA HDN and vice versa. On the other hand the supported catalyst were tested in order to study the influence of the amount of Ni in the HDA activity of Phe.
