specific Embodiment approach

[0114] The experimental system of the invention can carry out supercritical water gasification, oxidation and partial oxidation experiments of municipal sludge and organic waste water in a tubular reactor. The specific implementation is as follows:

[0115] (1) Open valves V8, V9, V10 and V17, and close other valves.

[0116] (2) The material enters the material preheater 6 after being pressurized by the material pump P2, and the preheated material enters the tubular reactor 11.

[0117] (3) The hydrogen peroxide solution enters the hydrogen peroxide solution preheater 7 after being pressurized by the hydrogen peroxide solution pump P3, and the preheated hydrogen peroxide solution enters the tubular reactor 11.

[0118] (4) The reacted fluid enters the gas-liquid separator 18 after being cooled and depressurized, and then the gas product and the liquid product are sampled respectively.

[0119] The experimental system of the invention can carry out material flow corrosion ex...
