Ensaios de calorimetria e análise termogravimétrica em amostras aleatórias e desconhecidas

Abstract

The analysis of calorimetric and thermogravimetric properties has been increasingly important in the identification and proof of the composition of random samples, due to the large scope of this tests and to the evolution of the machinery used. Discover the properties of a substance and being able to categorize it gives space to diverse applications and allow a better comprehension of what can be this compound used for. The present project was carried out with the equipment of the Heat and Mass Transfer Laboratory at the Federal University of Uberlandia, where 5 different samples were selected and the tests of calorimetry and thermogravimetric analysis realized according to the national and international regulations. Finally, it was possible to identify the five samples in relation to their composition and distribution of organic and inorganic matter for all of them. This realization was possible due to the analysis of calorific power and to the properties obtained by the thermogravimetric analysis, moisture, volatiles, ashes and fix carbon percentages. Furthermore, the flash point was determined for samples 1 and 2.
