GASIFICATION CHARACTERISTICS OF ADENOSINE TRIPHOSPHATE IN SUPERCRITICAL WATER

摘要

Phosphorus is known as one of three major elements of fertilizer, essential substance for agriculture,rnand resource which is concerned about the depletion in the near future. Thus, it is important to establish thernphosphorus recycling system. To confirm gasification characteristics of organics including phosphorus underrnhydrothermal condition, adenosine triphosphate (ATP) disodium salt hydrate was employed as model compound inrnthis study. About 50 % of carbon gasification efficiency could be confirmed after 40 s of hydrothermal treatment atrn400 ℃. The gasification rate constant was determined to be 4.49×10-2/s. Main component of the product gas wasrncarbon monoxide, and its composition increased with residence time and temperature. Mineralization of organicrnphosphorus resulted in phosphate ion in liquid phase.
