摘要: Abstract At the temperature of 693 K and water densities from 0.10 to 0.30 g/cm3, co-pyrolysis residual oil polyethylene in sub- supercritical (sub-CW SCW) was experimentally investigated. With increase density, phase structure system may evolve a liquid/liquid/solid three-phase liquid/solid two-phase one. By with oil, H-rich paraffins, main pyrolysis product polyethylene, are released continuously into reaction system. higher favorable structure, contact aromatic radicals paraffins that is promoted, ensuring coupling between networks polyethylene. Consequently, dealkylation follow desired mechanism by which production coke-inducing components effectively depressed. A significantly reduced coke yield observed sub-CW SCW.
