The heavy oil from the Mordovo–Karmalskoye oil field is cracked in the presence of silica-alumina Al-Si catalyst and Al-Si catalyst modified with NiCrWC. The composition of saturated and aromatic compounds before and after catalytic cracking is studied. It is shown that in the presence of a modified NiCrWC/Al-Si catalyst, the destruction reactions resin-asphaltene components proceed more intensively than during cracking in the presence of Al-Si. Transformations of hydrocarbons during cracking of heavy oil in the presence of NiCrWC/Al-Si catalyst are more intensive as evidenced by the predominance of low-molecular homologues of normal and iso-structure alkanes over high-molecular ones and increased contents of C7–C10 alkylbenzenes, unsubstituted naphthalene, and methylnaphthalenes. This catalyst contributes to the complete decomposition of high-molecular cyclanes, mono- and trinaphthenoarenes. It has been shown that NiCrWC/Al-Si catalyst the formation of a larger amount of low-molecular-weight n-alkanes compared to high-molecular ones. [ABSTRACT FROM AUTHOR] |
