Characterization Of Bitumen Research Articles

Characterization of Bitumens and Coals: GEOLOGIC NOTES

Elemental analyses can be used to distinguish many bitumens and coals by plotting the data on an H/C versus (N + S)/0 diagram.

Characterization of bitumens by pyrolysis gas chromatography

A method for bitumen analysis by pyrolysis gas chromatography is described. The characteristic ratio of light unsaturated and saturated hydrocarbons in bitumen pyrolyzate was used for the determination of the maltene and asphaltene fractions in bitumens. Bitumens of various types and origins were investigated.

Studies on bitumen: Part 1. Characterization of bitumen by use of physical methods

Gel permeation chromatography, spectroscopy measurements, densimetric analysis, mass spectrometry and spark source mass spectrometry were used to study maltenes fractions and asphaltenes components of a soft bitumen. Results from spectroscopy and mass spectrometry measurements indicated that the bitumen was less aromatic in character than indicated by densimetric analysis. The degree of conjugation in fractions was observed to increase as the molecular weights of fractions increased.

The thermal analysis—hydrogen flame ionization detector system for characterizing organic materials

The combination technique of thermal analysis—flame ionization detection (TAFID) offers attractive new possibilities for the precise measurement of the volatilization patterns of a wide variety of organic materials. Advantages over other methods are due chiefly to the sensitivity, specificity, and small sample requirement of the flame detector. Essential features of apparatus design are a close coupling of the detector to the sample furnace and provision for operating the detector at high temperatures in order to avoid condensation and thus allow quantitative measurements. Advances that have been made in instrumentation of the system provide speed and convenience. Recent improvements in techniques and apparatus will be discussed. The wide applicability of this approach to thermal analysis will be illustrated by a number of methods developed for specific purposes, including the characterization of various polymers, oils, bitumens, rubber compositions, and other organic materials.
