2016 - 2017 - Quality Control in Biofuels
In recent years, interest in research development with a focus on alternative and renewable sources of energy has grown. An alternative to reduce dependence on fossil fuels is to encourage the use of biofuels in the industrial and transport sectors as a substitute for fossil derivatives. From the entry of biodiesel in the energy matrixes of several countries, it was necessary to develop a series of regulations that define the minimum quality parameters for its use in engines, as well as transportation and storage.
The project proposal is to use analytical techniques such as infrared spectroscopy (FTIR) as well as isotope ratio mass spectrometry (IRMS) as an alternative for biofuel quality control in conjunction with mathematical tools such as multivariate analysis. Articles in international journals (Energy Fuel and Chemometrics and Intelligent Laboratory Systems) were published proving this application.
2014 - 2016 - Environmental Monitoring in Landfill
In Brazil, landfills are the only form of final waste disposal still permitted by law. However, this technique also poses risks of pollution, mainly for surface and groundwater that can be used for human consumption. Therefore, environmental monitoring of water resources is extremely necessary as the leachate can compromise the quality and use of surface water collections and groundwater around landfills.
In this context, taking into account the polluting potential of a landfill, the project aimed to identify possible points of contamination in groundwater and surface water in the area of influence of the landfill in Osório / RS. For the work, conventional physical-chemical parameters were used, such as the determination of anions, metals, conductivity, pH as well as the use of an alternative parameter that assesses the degradation of organic matter by microorganisms through stable carbon isotopes of the dissolved inorganic carbon in the Water. This project was coordinated by Dr. Luiz Frederico Rodrigues and resulted in publications and scientific submissions in international journals (Environmental Science and Pollution Research, International Journal of Integrated Waste Management, Science and Technology, respectively), conference presentations and a co-orientation Masters…
2013 - 2015 - Shale Gas
Shale Studies as Non-Conventional Reservoirs: An Integrated Approach between Petrology, Geochemistry, Petrophysics and Geomechanics. Project
financed by Petrobras. The analytical techniques employed in this project were elementary analysis (carbon, hydrogen, sulfur, nitrogen) and the analysis
thermogravimetric using a magnetic suspension scale for high pressures. Through these analyzes, it is possible to predict how much gas (methane, carbon dioxide) a layer of shale will be able to adsorb at a certain depth. This information is important to estimate the volume of gas that can be explored in a given reservoir. Technicians and researchers were hired to compose the human resources for this project ...
2010 - 2015 - Conegas I
Project financed by Petrobras that aimed to study unconventional sources of alternative energy related to fossil fuels, such as gas hydrates in the Rio Grande Cone pellet basin, Southern Brazil. Characterization of geochemical zones and their relationship with microbiology through chemical analysis of marine sediments, interstitial water, free gases, hydrocarbons and their respective stable isotopes. The analytical techniques employed in this project were optical spectrometry with inductively coupled plasma, ion chromatography, elemental analysis (carbon, hydrogen, sulfur, nitrogen), isotopic ratio mass spectrometry, gas chromatography. Technicians and researchers were hired to compose the human resources for this project. It should be noted that the project is of economic importance, because due to the high amount of gas in the hydrate structure,
countries like Japan and Canada are already in the process of using this resource as an alternative energy source...
2009 - 2010 - Validation of methods in the National Agricultural Laboratories
The project fits within the strengthening and support of research, development and validation of methods and other laboratory activities in the National Agricultural Laboratories through the grant and grants for Technological Promotion and Innovative Extension from CNPq Many Brazilian products (meat, honey) were prevented from be traded with European Union and US countries due to the lack of analytical information on the possible presence of metals harmful to health. Due to Brazil's interest in exporting its products to European and North American trade, this project aims to validate methods to ensure the quality of export products and in the near future, implement a routine analysis in the National Agricultural Laboratories (LANAGROS) to quality control of Brazilian products. Title of the Work Plan Development of analytical methods for the determination of Hg and As in honey by ICP OES The specific objectives are: 1) To develop a methodology for the decomposition of honey; 2) Develop a methodology for the determination of As and Hg in honey by ICP OES. 3) Validate the method developed according to directive 2002/657 / EC. 4) Apply the method developed for
analysis of honey from different sources...
2006 - 2010 - Quality control of raw materials used in the production of polyurethanes
Development of analytical methodologies for the determination of metals in raw materials used in the production of polyurethanes. This project was developed with the objective of meeting a Bayer industrial difficulty. Polymeric diphenylmethane diisocyanate (PMDI) and dianiline diphenylmethane (MDA) are important raw materials in the polyurethane industry. These products have a wide application in several areas such as medicine, catalysis and electronics. Currently, considerable interest has been given in relation to the presence of metallic contaminants in raw materials for the production of polymers, as they influence the processing and alter the thermal properties of the products.
Project objectives: * Development of procedures for the decomposition of polyols, MDA, MDI by different decomposition techniques using a closed system with microwave heating and a microwave initiated combustion system for the subsequent determination of various metals and halogens by ICP-MS and ICP OES. * Application of DSS-GF AAS for the determination of Cr, Co, Cu, Fe, Ni, Na and K in raw materials (MDA and MDI) used in the production of polyurethanes.
