Active carbon with high resistance to crushing, useful as catalyst, catalyst support, particularly for oxidizing mercaptans to disulfides, or selective adsorbants

摘要

Active carbon (A) has total pore volume at least 1, preferably 1.2, ml/g; bed resistance (in the Shell bulk crushing test) at least 1, preferably 1.7, MPa, and BET surface at least 500, preferably 700, m 2/g. Independent claims are also included for the following: (1) a method for impregnating (A) with first an aqueous solution of a metal complex (I) and then with a solution of base (II); and (2) catalyst (B) for oxidation of mercaptans to disulfides that comprises (I) fixed to (A).
