Abstract:
Phosphorus is an important nutrient for living organism and a non
substitutable constituent of agricultural fertilizers. In this study, the phosphorus
behavior in supercritical water gasification (SCWG) of sewage sludge was investigated.
A continuous react or was employed in this study. The experimental condition has been
decided at 500, 550 and 600 C and varies residence time 5, 10, 20, 30, 40, 50 and 60 s
and a fix pressure 25 MPa . The effect of temperature and residence time for behavior of
phosphorus in supercritical water gasification (SCWG) of sewage sludge was
investigated. The result showed that the organic phosphorus (OP) was rapidly converted
into inorganic phosphorus (IP) at 5 10 s.
