In this study, the commercial ion exchange resin Amberlyst A26 (OH) were used in the deacidification step of vegetable oil refining procedures. The FFA in vegetable oil was removed by continuious packed bed without adding solvent. The effect of FFA removal efficiency, resin utilization efficiency, resin adsorption capability and the total amount of FFA removal were evaluated for the bed height, feed flow rate and initial acid value of the oil.
For the ion exchange resin, the mass transfer performance of the packed bed can be known from the trend of the breakthrough curve. When the bed height is higher and the feed flow rate is slower and the initial acid value of the oil is lower, the breakthrough curve is closer the origin ,more steep and faster to achieve equilibrium, with a better efficiency of FFA removal.
The effect of bed height on resin utilization efficiency, FFA removal efficiency and the total amount of FFA removal was significant. The effect of feed flow rate was significant for FFA removal efficiency and resin utilization efficiency. And the initial acid value has a significant effect on the resin adsorption capacity, FFA removal efficiency and the total amount of FFA removal.
The maximum FFA removal efficiency is expected, and this study is recommended to be carried out at a bed height of 7 cm, a feed rate of 4 ml / min and an initial acid value of 6.5 mg KOH / g.The model of the free fatty acid adsorbed by the ion exchange resin packed bed is described by the response surface regression model. The minimal P value and the R2 value close to 1, indicate that the model of the response surface method can accurately show the change of the experimental data.
