摘要: Abstract A novel reactor, combining the advantages of MODAR horizontal stirred dynamic gas seal wall and cool was designed manufactured to overcome problems encountered in continuous supercritical water oxidation real waste, especially semi-solid state. It is a Y-shaped reactor consisting an inclined reaction section on left vertical separation right. Nine experiments were carried out test performance using municipal sewage sludge (MSS), with 12% dry solid (DS) content, as representative sample waste. The results suggest that MSS, without preheating, can be safely efficiently treated by adding 12.5% isopropyl alcohol (IPA) pure water, volume which at least 2.5 times MSS. organic carbon removal efficiency up 99.94%. Inorganic particles from MSS are continually pushed forward section, completely separated stored bottom section. Clean effluents, comprising gases main products, released top outlet. flow regime considered plug flow. Counter-current not observed during tests. excellent situ suggests this has potential for application various hydrothermal processes involve high content inorganic particles.
