Abstract Kitchen waste oil collector was prepared by modifying kitchen waste oil to treat high carbon fly ash. The optimum mechanical activation time of high carbon fly ash raw ash was determined by mechanical activation test, the decarbonization performance law of the kitchen waste oil collector was obtained by flotation tests under different temperatures and compared with that of conventional collector kerosene, the collectors and decarbonization products were systematically analyzed by FTIR, SEM, TG and other techniques. The results showed that the optimum mechanical activation time was 30min, under the condition of optimum temperature, the calorific value of flotation carbon can meet the requirements of medium and high calorific value fuel, and the mineral composition of decarbonized fly ash product can reach the standard of I-class fly ash. It is of great significance to environmental protection, energy conservation and emission reduction, and comprehensive utilization of resources, which has truly realized the goal of "treating waste with waste" and "turning waste into treasure".

Key words： kitchen waste oil kitchen waste oil collector high carbon fly ash flotation decarbonization temperature conditions product analysis
