Aquathermolysis of Heavy Oil Model Compounds

Abstract:

Article Preview

Tetrahydrothiophene and thiophene are taken as models of aliphatic and aromatic sulfides in aquathermolysis reaction of heavy oil respectively. Experimental data indicates C-S bond of sulfide compound are broken down. The results of thermodynamic calculation indicate that transform rates of two reactants arrive at 100% when the ratio of water/tetrahydrothiophene is more than 3 or the ratio of water/thiophene is more than 4 respectively, temperature and pressure and feed ratio have little effects on equilibrium composition simultaneously. High feed-in ratio is propitious to yield when water is insufficient, and the gaseous products improve with increasing temperature and decreasing pressure.
