The utility model relates to a polycyclic aromatic hydrocarbons hydrogen transfer trades viscous crude upgrading analogue means with CO water heat altered. And convenient for operation, and energy consumption is low, the high pressure retort comprises electromagnetic stirr ware, anxious cold coil pipe, first thermocouple, cover and the pressure pan body, the pressure pan body is installed at the heating furnace inner chamber, and the top of the pressure pan body is equipped with the cover, installation electromagnetic stirr ware, anxious cold coil pipe, first thermocouple on the cover, and electromagnetic stirr ware and first thermocouple have been worn to the middle part of the upside boss of cover, and the bottom of electromagnetic stirr ware is installed at the pressure pan internally, and well upper portion cover has anxious cold coil pipe, and the top of electromagnetic stirr ware is connected to control system through the control line, the beneficial effects are that: can realize simply, fast through setting up gas -liquid sampling system that the viscous crude faces the continuous sampling of CO hydrothermal upgrading, more swift, accurate survey polycyclic aromatic hydrocarbons hydrogen transfer trades the effect to the viscous crude upgrading with CO water heat altered.
