Resumo
The thermogravimetry has emerged to be an alternative technique
for the analysis of biodiesel due to the rapidly methods, sensitivity and
accuracy. Because of different characteristics between biodiesel and petroleum
products, is difficult to adapt standard methods as in many cases the result
dimension is quite distinct by capability of equipment detection. The micro
residue of carbon test is one of the techniques which do not accomplish the
biodiesel requirements. There is a deviation between national legislation and
stipulated technical standard, thru ASTM D4530 for petroleum samples, the test
should be applied with the residual of 0,10% (w/w) once previously distilled to
remove 90% (v/v) of the total volume. Therefore thermogravimetry turn as an
alternative for essay of micro carbon residue based on the results of this study
which perform in biodiesel analysis and it has several advantages.
