The objective of this research is to find a material that can significantly extend the useful life of components used in Supercritical water gasification (SCWG).SCWG has the potential to be extremely clean and efficient use of coal resources. However, widespread adoption of SCWG technology is currently held back by the high cost of limited reactor lifespan. The mixture of water, coal, and catalysts reaches a highly corrosive state right before reaching water’s critical point, corroding the reactor and significantly shortening its useful life.In order to make SCWG economically viable, either highly resilient material optimized for use in coal SCWG or alternative anti-corrosion methods are necessary.Successful outcome of this project will allow further development of economical components in the process of SCWG by potential companies providing a clean and efficient use of the vast reserve of coal in China.
