1 methylnaphthalene

Wash oil, the feed of this study, was provided by OCI Company Ltd. (Seoul, Korea). Naphthalene (NA, 99% purity), QU (98% purity), IN (≥99% purity), 2-methylNaphthalene (2MNA, 97% purity), 1-methylNaphthalene (1MNA, ≥95% purity), and biphenyl (BP, ≥99.5% purity), which were used GC identification or quantification of the constitutive components presenting in the wash oil, were purchased from Sigma Aldrich, Seoul, Korea. Methanol (≥99.5% purity) and n-hexane (≥99% purity), used as the solvent of each operation in this study, were also purchased from Sigma-Aldrich, Seoul, Korea. In this study, the above-mentioned eight kinds of commercial reagents were used without further purification.

n-Octane (99+%), n-hexadecane (99%) and 1-hexene (97%) were received from Acros (Belgium). Cumene, 1-methylnaphthalene and toluene (99.5%) were received from Sigma Aldrich. N-heptane was received from Alfa Aesar. Pyrolysis liquids were kindly supplied by Urbaser, Spain. All chemicals were used as received. Table 2 shows the composition of the model mixture used in this study, whereas the chemical composition of the real pyrolysis mixture is given in Table 3.

Commercially available Torlon® 4000T-LV and Matrimid®5218 were purchased from Solvay Advanced Polymers (Alpharetta, GA) and Huntsman, respectively. SBAD-1, DUCKY-9, and DUCKY-10 polymers were synthesized from literature procedures detailed in two previous publications^{4 ,5 (link)}. Two real crude oils (Permian and Arabian light crude oils) were provided from ExxonMobil Technology and Engineering Company. The experimental results of the two fractionations were published previously^{4 ,5 (link)}.
