Scope
Main technical content: This document specifies a test method for determining the composition of mixed aromatics in olefins produced by cracking coal-based naphtha using full two-dimensional gas chromatography combined with a mass spectrometer detector (GC×GC-MS). This document is applicable to the 30% to 70% mixed aromatics synthesized in the process of cracking coal-based naphtha to produce olefins.
