| Abstract: | [Objective] The research aimed to study application of the diatomite in soap removal of the soybean oil without water.[Method] Centrifugal soap-removal oil as test sample,diatomite as adsorbent,the optimal condition of soap removal of the soybean oil without water was studied.[Result] Under 0.5% of diatomite dosage,110 ℃ of adsorption temperature and 25 min of adsorption time,residual soap amount in obtained oil sample was 68.5 mg/kg,and residual phosphorus amount was 1.317 mg/kg,which was better than oil quality after soap removal by washing in industry.[Conclusion] It was feasible to use diatomite in soap removal of the soybean oil. |
| Keywords: | Diatomite Soap removal without water The amount of residual soap The amount of residual phosphorus |
