Abstract

1,146,250. Gas chromatography. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 20 Nov., 1967 [21 Nov., 1966], No. 52714/67. Heading B1L. A process for the separation of mixtures, especially hydrocarbon mixtures, by means of gas chromatography entails the use of at least two columns of different selectivity, the effluent from one column being quantitatively collected in fractions by freezing out the fraction from the gas stream in a small vessel, e.g. a U-tube immersed in liquid nitrogen, containing a filler material, such as diatomaceous earth, corundum or firebrick, which is suitably coated with a non volatile material such as a silicone grease or a high boiling hydrocarbon, injection of the frozen out fraction into a subsequent chromatography column being achieved by raising the temperature of the small vessel while carrier gas to the subsequent column is passing continuously through. The process is exemplified by the analysis of naphtha into its constituents, a flow sheet being provided in which four columns are employed, of which two use a silicone oil and the others tris-cyanoethoxypropane as the immobile liquid phase on conventional adsorbents, the carrier gas used being hydrogen.
