“…VPR, using sulfuric reactors has been employed previously for the characterization of automobile exhaust gases (4-7), the 0003-2700/79/0351-1529$01.00/0 reagent being used to subtract olefins and aromatic hydrocarbons. In all of these applications, the reactors were operated at relatively low temperatures; Innes et al (6) used a reactor at 54 °C to subtract olefins and simple aromatic hydrocarbons in the C6-C8 range. Molecular Sieve 5A has been used extensively in the analysis of alkanes in petroleum products (4,(7)(8)(9).…”

The application of on-line reactors to aid in the discrimination between various classes of hydrocarbons in shale oil and the volatile gases evolved in laboratory pyrolysis of oil shale is described. A pre-column reactor of sulfuric acid supported on diatomite serves to subtract alkenes, aromatics, and the various oxygen-, nitrogen-, and sulfur-containing species within the complex shale oil gas chromatographic profile. The unsubtracted alkanes serve to provide informative fingerprint comparisons between oils produced by various retorting processes and laboratory evolved samples. The procedures are particularly effective when interfaced with capillary column gas chromatography. Further differentiation among alkanes may be gained by the use of on-line molecular sieve precolumns which remove n-alkanes, leaving branched chain and
