This paper reports on the residual asphalts obtained from three Nigerian medium crudes chemically treated with elemental sulfur at 210 to 250{degrees} C. The course of the reaction was followed by monitoring the growth of the asphaltene content of the products. The sulfurization reaction led to 5- to 10-fold increases in the asphaltene content of the products. The asphaltene content of one of the samples initially increased with temperature from 210 to 240{degrees}C. and then dropped sharply. The results obtained revealed that the optimum temperature of the sulfurization reaction was 240{degrees}C.
