Rapid method for determination of content of unsaturated hydrocarbons in naphtha cuts
The method to determine total content of unsaturated hydrocarbons in naphtha cuts from reforming, cracking, and pyrolysis consisted of exhaustive catalytic hydrogenation of the unsaturated hydrocarbons, with detection of the hydrogen consumed in the hydrogenation reaction. The analyses were performed in a KhL-4 chromatography; the gas flow plan is shown. Preliminary experiments with saturated hydrocarbons (hexane, octane, decane) were performed. Naphthene experiments (methylcyclopentane, cyclohexane) showed no peak to indicate an increase in hydrogen concentration. No hydrogenation was observed in experiments with benzene and toluene. A comparison was made from analyses using the GOST 2070-82 and the rapid method as applied to IBP-180/sup 0/C cuts from reformer naphthas produced under varying conditions of severity.
