Abstract:
The invention relates to a method for producing an adsorbent, in particular a bleaching earth, wherein a clay material having: a surface area of 180 to 300 m2/g; a total pore volume of 0.5 to 0.7 ml/l; wherein at least 60% of the total pore volume are provided by pores having a pore diameter of at least 140 A, at least 40% of the total pore volume is provided by pores having a pore diameter of less than 250 A and at least 15% of the total pore volume are provided by pores having a pore diameter of 140 to 250 A; and said clay material having an amorphous structure according to XRD data; is activated by an activation procedure. Further, the invention relates to an adsorbent as obtained by the method and a method for purification of oils, fats and biofuels.
