ABSTRACT:
In the decoloration of an animal and vegetable fat and oil with clay, an oil-containing clay is obtained as by-products. Good recovery of oil is attained by subjecting the oil-containing clay to an alkali treatment under high temperature and high pressure, adding an acid in an amount necessary for neutralization and removing the floating oil. Clay sludges and waste water after the recovery of oil can be easily disposed without causing the environmental contamination.
