Publication number: 20080223756Abstract: A method for producing an adsorbing agent, an absorbing agent obtained by the method, and its use as bleaching earth, in particular for refining oils and fats, is described. In the method according to the invention, a raw clay with a specific surface area of more than 200 m2/g, an ion exchange capacity of more than 40 meq/100 g and a pore volume of more than 0.5 ml/g is used. At least 40% of the pore volume are provided by pores which have a pore diameter of at least 14 nm, and at most 25% of the pore volume are provided by pores which have a diameter of less than 7.5 nm. Surface activation with an acid gives an adsorbing agent which has a bleaching activity which partly exceeds that of high performance bleaching earths obtained by intensive dealuminization and washing with strong acid.Type: ApplicationFiled: June 8, 2005Publication date: September 18, 2008Applicant: SUD-CHEMIE AGInventor: Klaus Schurz
