摘要：

A new TGA method for evaluating the carbon residue of heavy fuel oil (TGCR) is proposed. Using a Netzsch STA 409 thermobalance it is possible to submit the sample to a high heating rate (> 750 degrees C min(-1)) in nitrogen obtaining a rapid pyrolysis followed by the combustion of carbon residue in oxygen. The results obtained for eight samples of heavy fuel oil are compared with the asphaltene content and with the Conradson carbon residue (CCR). This method is easy and rapid to carry out; it is characterized by good repeatability and may be widely employed in routine laboratories for fuel oil control.
