✦ Synopsis
Based on thermogravimetric principles a new distillation method for petroleum products and coalderived liquids has been developed. The boiling point distributions of five petroleum fractions (kerosene; 128-228X; light gas oil, 178-298'C; middle gas oil, 200360°C; vacuum gas oil, 268-565'C; and high vacuum gas oil, 305-6WC) and one highly aromatic coal-tar fraction (wash oil, 180-310X) were obtained. The results are in good agreement with those obtained by standard (ASTM) distillation methods. The amount of sample required is very small (~10 mg) and can be solid or liquid. The experiments at normal pressure were carried out using a specially designed sample holder made of quartz. In thecaseof high-boiling-point fractions (distillation under reduced pressure) a normal sample holder can be used. The results are automatically recorded as temperature versus weight loss.
