Resumen
In recent years, several changes in the impregnation techniques of the active phase on mesoporous supports have been developed to improve results. One option reported the synthesis of catalysts by incipient impregnation assisted by organic chelating agent derived from carboxylic acids such as citric acid, nitrilotriacetic, EDTA, among others [1, 2]. Based on those studies, this research work presents the evaluation of a series of CoMoS catalysts supported on three-dimensional mesoporous silica, which were prepared by incipient impregnation assisted by soluble polyacrylic acid oligomers with different molecular weights (1,000 and 5,000 UMA, approximately). Polyacrylic acid oligomers were prepared by radical polymerization in aqueous solution. The control variables during the impregnation process were solution pH and the level of humidification of the CoMo precursor phase.
