Profile and objective:

Development in the catalysis area and the quality control of petroleum products

Professional experience:

April 2003- July 2005. PDVSA Petroleos de Venezuela S.A., Miranda- Venezuela. Research in Catalysis:

-I worked in a R & D project preparing catalysts cobalt supported on silica for Gas to liquids tecnologies. Preparation of catalytic support based on silica by emulsions methods and supported metallic catalysts by the impregnation and precipitation methods.

- Preparation of manganese complexes employing bidentate amine lingand by the precipitation method for the selective oxidation, in liquid phase, of hydrocarbons and streams employed in diesel fuels formulations.

- Catalysts evaluation to bench and laboratory scale in the Synthesis Fischer-Tropsch and Selective oxidation reactions following the activities and selectivities of catalysts by GC.

July 2005- April 2009. PDVSA Petroleos de Venezuela S.A., Miranda- Venezuela. Physicochemical characterization of heterogeneous catalysts:

-Installation, calibration, operation and maintenance of physisorption equipments: ASAP 2020 Micromeritics. Characterization of catalyts by the physisorption technique of Nitrogen and CO2: determining textural properties.

-Installation, calibration, operation and maintenance of Chemisorption equipments: ASAP 2010 Micromeritics. Characterization of catalyts by the chemisorption technique of hydrogen and CO (Carbon monoxide): determining dispersion and metal area.

-Installation, calibration, operation and maintenance of Thermogravimetric analysis equipments: Characterization of catalyts by thermogravimetric analysis coupled to quadrupole mass (TGA-MS), Differential thermal analysis (DTA) and DSC.

-Installation, calibration, operation and maintenance of temperature programmed equipments: AUTOCHEM, Micromeritics. Characterization of catalyts by the temperature programmed techniques: Oxidation, reduction and reaction.

-Operating of equipments to pyridine adsorption followed by FTIR.

April 2009- Present. PDVSA Petroleos de Venezuela S.A., Miranda- Venezuela. Products quality Department:

-Physicochemical characterization of fuels using ASTM methods: density, viscosity, destillation, gums, corrosión, pour point, flash point and others by the Quality Standard ISO-17025.

-Knowlodge of Quality Standard ISO-17025.

-Responsible for quality testing methodologies of fuels: Density and Vapor Pressure. Study of uncertainty of both methodologies for validation. Participation in internal and external audits of both methodologies.

-Participation in interlaboratory tests for gasolines.

-Compative study of the effect of gasoline-oxygenated (ethanol or MTBE) blends on the properties of SBR, NBR and FKM elastomeric materials, using the standard SAE J-200.

-Synthesis of oxygenated compounds starting from glycerol and acetone, using Amberlyst-35 as a heterogeneuos catalyst, in a batch scale.

-Preparation of silica supported zirconia catalysts for synthesis of diethyl carbonate, new oxygenated compound used in gasoline, starting from Bioethanol and CO2 in a batch reactor.

- Skills in planning, managing and executing projects R & D: New environmetally friendly fuels.
