摘　　要：Viscous behavior is important for the process design, especially for the non-Newtonian fluid. In this study, the viscous behaviors of slurry, i.e., 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)im ide([Hmim][NTf_(2)])/titanium dioxide(TiO_(2))-polyethylene glycol(PEG200), were determined experimentally and systematically. The pressure drop was estimated when [Hmim][NTf_(2)]/TiO_(2)-PEG200 was used as the solvent in the absorption/desorption towers. The results show that the slurry belongs to the non-Newtonian fluid with shear-thinning behavior. High temperature and low solid content are beneficial to reduce the viscosity of [Hmim][NTf_(2)]/TiO_(2)-PEG200, and the presence of [Hmim][NTf_(2)] can effectively reduce the viscosity of the slurry. In addition, high temperature is preferable for reducing the pressure drop, and the pressure drop of slurry with the solid content value of 8.0%(mass) can reduce by 28.0%when the temperature increases from 313 to 333 K.
