Method to quantitatively analyze conjugated dienes in hydrocarbon feeds and products as an indicator of fouling potential

A method to quantify the conjugated dienes in a feedstream including the steps of dissolving 4-methyl-1,2,4-trazoline-3,5-dione (MTAD) in said feedstream, and determining the molar concentration of said conjugated dienes and/or the carbon number distribution of said conjugated dienes by GC/MS and GC/NCD (Nitrogen Chemiluminescence Detection).

Um método para quantify os dienes conjugated em um feedstream including as etapas de dissolver 4-methyl-1,2,4-trazoline-3,5-dione (MTAD) em feedstream dito, e de determinar a concentração molar de dienes conjugated ditos e/ou a distribuição do número do carbono de dienes conjugated ditos por GC/MS e por GC/NCD (deteção do chemiluminescence do nitrogênio).
