Evaluation of surfactants used in biomass coal-water slurries
Abstract：After the rice-stalks were dried and powdered,certain amounts of the rice stalk powders were mixed with coal to prepare the biomass coal-water-slurries.Influence on the slurry ability and stability of biomass CWS with different type and dosage of additives,and different shear rates were studied.The results show that the slurry ability is ineffective when adds the sole ionic or non-ionic surfactants in biomass CWS,and the higher dosage uses,the higher apparent viscosity of biomass CWS is.However,the slurry ability of biomass CWS is improved after using mixed surfactant with ionic and non-ionic surfactants at a range of different percentage,and the optimum scheme is MF∶ST=4∶1and MF∶02=6∶1.The stability of biomass CWS can last more than a week,which is considered excellent.
