For the characterization of hydrocarbons, thermogravimetric (TG) analysis techniques have proved very useful. However, TG analysis by itself does not identify the decomposition products. When TG analysis is coupled with evolved product analysis by FT-IR, a wealth of information regarding the composition of pyrolysis and oxidation products is obtained. The application of TG-FTIR to coal and petroleum source rock has been described in two recent publications. The most difficult to analyze effluents are the heavy decomposition products which condense at room temperature. These condensates such as tars from coal, asphaltenes and pre-asphaltenes from petroleum or coal derived liquids, and oligomers from polymers are invariably the major evolved products from most hydrocarbons. Their amount and composition are important in predicting the behavior of the hydrocarbon in an upgrading or conversion application. A recently designed apparatus, the Bomem TG/Plus, which combines a DEUPONT 951 TGA with a multi-pass gas cell and a MICHELSON FT-IR provides a standard TG analysis while simultaneously monitoring these condensible products as well as gases. The purpose of this paper is to describe the application of the TG/PLUS for the analysis of heavy hydrocarbons.
