The use of pyrolysis chromatography for the evaluation of steam-cracking naphtha feedstocks in plant conditions is described. The laboratory pyrolysis involves a pulse quartz tube reactor and an online dual gas chromatograph equipped with a system of capillary columns and detectors. The quantified yields of pyrolysis products obtained in laboratory are transferred to the plant conditions using an artificial neural network.
