The　paper　aimed　to　build　a　model　for　high-temperature　coal　tar　(HTCT)　catalytic　hydrocracking　in　supercritical　xylene　with　the　conceptual　design　of　energy　self-sustainability　based　on　Aspen　Plus.　The　following　tasks　were　done　to　boost　the　reliability　of　the　model:　selecting　reasonable　model　compounds　for　HTCT,　using　pseudo-components　to　describe　the　nature　of　products　and　choosing　reliable　property　methods　for　blocks.　Results　showed　products　can　be　well　separated　by　the　block　rectifying　column　(DIST);　additionally,　the　total　heat　recovery　was　as　high　as　2,355　kW　h,　among　which　1,434　kW　h　was　from　the　heat　carried　in　the　outlet　stream　of　REACTOR.　The　total　energy　consumed　by　the　energy　consumption　equipments　was　882.5　kW　h.
