Composition and structure characterization of coker gas oils derived from FCC decant oil before and after hydrotreating was written by Cai, Xinheng;Liu, Yingrong;Liu, Zelong;Fan, Qiming;Tian, Songbai.

Coker gas oils derived from FCC decant oil before and after hydrotreating were characterized by GC-FID/MS and NMR. A total of 121 aromatic compounds in the coke gas oils were identified and quantitated, including polycyclic aromatic hydrocarbons (PAHs), hydrogenated PAHs, C0-C2 substituted PAHs, thiophenic compounds and carbazoles. The compositional and structural changes in process of hydrotreating-delayed coking of FCC decant oil were also investigated. Coker gas oils derived from FCC decant oils with and without hydrotreating had different compound compositions, though their hydrocarbon group composition were quite similar. The gas oil from hydrotreated FCC decant oil had less unsubstituted polycyclic aromatic and heteroaromatic hydrocarbons, while more alkyl substituted aromatics and naphthenic-aromatics than that from the unhydrotreated one, implying that hydrotreating is beneficial for enhancing cracking and condensation reactions and improving liquid products in delayed coking of FCC decant oil. In the experiment, the researchers used many compounds, for example, Naphtho[2,1-b]benzofuran (cas: 205-39-0SDS of cas: 205-39-0).
Naphtho[2,1-b]benzofuran (cas: 205-39-0) belongs to benzofurans derivatives. Many natural or synthetic compounds containing benzofuran skeletons have been found to possess remarkable activity as agrochemicals and pharmaceuticals. Benzofurans have also made significant and distinctive contributions to biology. They exhibit several biological activities that range from antioxidant, antitubercular, antiplasmodial, insecticidal.SDS of cas: 205-39-0
