生物油的分离与乳化研究

o upgrading bio-oil for its application in internal-combustion engine, this paper have investigate a series of emulsions about bio-oil with 0# diesel oil, and the surfactant used in this work is 1-octanol. During the research, the parameters of water content, acid number, viscosity, heating value and stability of emulsions have been studied. The results shown that the emulsion oil may instead diesel oil with lower acid number and water content, good combustion property and excellence stability. Otherwise, emulsification process could separate bio-oil effectually: most light fractions of bio-oil enter into emulsion phase, most organic acids and heavy fractions of bio-oil preserving in water phase. It is a novel way for bio-oil upgrading and application with convenient operation.
