Abstract: The invention describes process for demetallation of vegetable oils and animal fats to reduce metal content below 1 ppm to make them suitable for hydroprocessing feedstocks. The process comprises acid treatment with very low concentration of acids, utilizing synergistic effect of phosphoric acid and citric acid, followed by counter-current treatment with clay without intermediate step of water washing and treatment with ion exchange resin.

Abstract translation: 本发明描述了植物油和动物脂肪脱金属的方法，以减少低于1ppm的金属含量，使其适用于加氢处理原料。 该方法包括使用非常低浓度的酸的酸处理，利用磷酸和柠檬酸的协同效应，然后用粘土进行逆流处理，无中间步骤用离子交换树脂进行水洗和处理。
