负载型固体碱对废弃油脂的脱酸脱色效果研究
Influences of deacidification and decolorization of waste oil using supported solid base
摘要
Abstract
Deacidification and decolorization are key processes of waste oil pretreatment. The solid base was made by immer-sion method, using activated carbon ( AC) and activated bentonite ( AB) as support, which was characterized by X-ray fluo-rescence, nitrogen adsorption. Influences of support ratio, concentration of impregnation solution, solid base amount, reac-tion time and reaction temperature on removal of free acid and colored impurities were investigated. The results show that the optimum parameters of solid base preparation are that AC ∶ AB=6 ∶ 4 and the concentration of impregnating solution is 10 g/L. The optimum operating conditions of this one-step process are that the amount of solid base is 150 mg/g, the reaction time is 30 min and the reaction temperature is 70 ℃. Under these conditions, the decoloration rate of waste oil reaches 54. 77%and the deacidification rate is as high as 90. 91%.关键词
