Hydrotreating catalysts are commonly used to produce clean fuels through the elimination of heteroatoms compounds. This review examines the existing literature about the effect of the metal active component, supports or additives on the performance of hydrotreating catalysts. It includes: (i) a brief overview of the metal active components and impregnating methods for hydrotreating catalysts. (ii) a summary of the influence of the common support (Al2O3 carrier or mixed oxides supports) nature on the hydrotreating activity. (iii) an introduction of three classes of additives, namely phosphate, boron and chelating agents, to improve the activity and selectivity.
Hydreating catalyst, support, additives, chelating agents.
