| dc.description | 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. | |
