Research progress of supercritical water oxidation based on transpiring wall reactor

The development of the technology of supercritical water oxidation（SCWO）is facing two major technical problems：corrosion and salt plugging. Transpiring wall reactor is the most effective solution to resolve these problems. This paper reviews the structural characteristics and the performance of the transpiring wall reactor in China and overseas. Problems still existing in the application of supercritical water oxidation based on transpiring wall reactor are discussed，such as performance of the porous wall，preheating of the feed，energy recovery and economy of the system，and corresponding solutions are proposed.
