ACTIVATED CARBON WITH IMPROVED MECHANICAL RESISTANCE, AND THE USES THEREOF, ESPECIALLY AS A CATALYST CARRIER

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).
