摘要：
The product distribution of pyrolysis of heavy oil in the supercritical methanol (SC-MeOH) was studied. It could be found that the pyrolysis reaction rate enhanced with the increase of temperature. Compared with reaction in N-2, the coking formation was promoted in SC-MeOH. It was attributed to "cage effect" caused by methanol. The aromatics and resins which can dissolve asphaltenes were isolated by cages. Therefore, more coke was formed by condensation of asphaltenes. A lumped reaction kinetic model modified by equilibrium mass fraction of aromatics and resins was established, which could describe and predict the products distribution in SC-MeOH.
