| Abstract The high consumption of fossil fuels and the exhaustion of light oil have brought the need of deep extraction and as a consequence the improvements in the catalyst design. Actually current researches have focused on the development of catalytic materials with high sulfur removal capacity [1]. According to the literature several authors agree that a ruthenium sulfide catalyst is a material with high catalytic activity [2-4], superior to the traditional molybdenum sulfide catalyst, making it an excellent candidate to meet the current challenge. In previous work by our group using a new ruthenium precursor it was achieved to synthesize ruthenium sulfide catalyst with catalytic activity higher than industrial ones [5-8]. Unfortunately the high cost of this catalyst is the main limitation despite its high development. In this research work a ruthenium sulfide catalyst promoted with titanium was synthesized; different titanium/ruthenium atomic ratio was studied; the synthesis was done according to the previous work reported by our group when a complex ruthenium precursor route was followed to synthesized the bimetallic complex; followed by an activation process. The Hydrodesulfurization (HDS) of dibenzothiophene (DBT) studies were carried out in a Parr model 4560 highpressure batch reactor and the materials were characterized by thermogravimetric analyses, scanning and transmission electron microscopy, X-ray diffraction, and surface area by BET method. The titanium showed a positive effect over ruthenium sulfide achieving catalytic activity some times greater than molybdenum sulfide base industrial catalysts; according to our results complex bimetallic precursor route reported previously is suitable way to achieve high activity titanium/ruthenium sulfide catalysts including high content of titanium. | |
