摘要: The authors present an experimental investigation of the residence time distribution (RTD) liquid in a gas-liquid upflow fixed-bed reactor with porous and nonporous particles air/Newtonian or non-Newtonian systems. piston-dispersion-exchange model Danckwerts boundary conditions was used to describe flow. In case particles, dynamic evolution tracer concentration described terms diffusion phenomena. An imperfect pulse method estimate parameters directly from experimentally nonideal input output response.
