The present invention provides a method of treating fats and oils containing low concentrations of aromatic halogen compounds and other contaminants by contacting the fats or oils with an adsorbing agent. The adsorbing agent contains a porous body and a non-protonic polar solvent held in the interiors of fine pores in the porous body to adsorb the contaminants. In one embodiment, the porous body also carries noble metal fine particles. In another embodiment, the adsorbing body comprises a solid acid for adsorbing the contaminants and there is a step of contacting the adsorbing body with an organic solvent to extract the adsorbed contaminants into the organic solvent.

Method of treating fats and oils

A processing apparatus capable of separating and recovering resins and metals, respectively, from an object being processed, which has resins and metals as its constituent, comprises a first gastight area (,), in which temperature and pressure are regulated so as to permit selective thermal decomposition of resins from the object (,) being processed, a second gastight area (,), which is partitioned from the first gastight area by an openable and closeable partition (,C) and in which temperature and pressure are regulated so as to permit selective vaporization of metals from the object, first recovering chamber (,) connected to the first gastight area for recovering gases produced by thermal decomposition of resins, and second recovering chamber (,) connected to the second gastight area for recovering vaporized metals.
