METHOD OF PRODUCING AMORPHOUS ADSORBENT AND ITS USE IN THE BLEACHING OF FATS AND/OR OILS |
摘要 |
<p>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 m 2 /g;
- a total pore volume of 0.6 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 Å, at least 40 % of the total pore volume is provided by pores having a pore diameter of less than 250 Å and at least 15 % of the total pore volume are provided by pores having a pore diameter of 140 to 250 Å; 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.</p> |
