Q1. What contributions have the authors mentioned in the paper "Mass transfer in gas-liquid slurry reactors" ?
A critical review is presented on the mass transfer characteristics of gas-liquid slurry reactors. The recent findings on the influence of the presence of solid particles on the following mass transfer parameters in slurry reactors are discussed: volumetric gas-liquid mass transfer coefficients ( kLa, kGa ), liquid-side mass transfer coefficients ( kL and k, ) and specific gas-slurry contact area ( a ). The second part of this paper reviews the recent progress in their knowledge and understanding of the enhancement of gas-slurry mass transfer due to the-presence of solids. Fiie different cases are distinguished, i. e. -enhanced mass transfer by physical adsorption on small particles, -enhanced mass transfer by fast homogeneous reactions in the slurry, due to inert particles, -enhanced mass transfer by homogeneous reaction in the liquid with dissolving particles, -enhanced mass transfer due to reactive particles and enhanced mass transfer due to catalytic particles in heterogeneous reactive systems.
