| Abstract: | Gas-liquid mass transfer and kinetic property of self-mixing disk turbine (SDT) stirred reactor in non-Newtonian fluid system are studied. Equation of gas-liquid transfer coefficient is derived from experimental result based on air-carboxymelthyl cellulose sodium salt aqueous system. Experimental result shows that SDT stirred reactor is superior to traditional disk turbine (DT). SDT is suitable to be used as a bioreactor in non-Newtonian fluid system. |
