SETT FOR OXIDATION AV EN SULFIDINNEHALLANDE VATTENLOSNING |
摘要 |
A method of treating an aqueous sodium sulfide solution, such as white liquor in kraft pulping systems, for the oxidation of the sulfide with oxygen in the presence of a specific activated carbon catalyst which is (a) a particulate activated carbon catalyst having an average particle diameter of 0.2-4 mm, a pore volume of at least 0.25 cc/g in pores with diameters of not smaller than 100 ANGSTROM and a pore volume of at least 35% of the total pore volume in pores with diameters of not smaller than 100 ANGSTROM or (b) a fibrous activated carbon catalyst having a specific surface area of 300-2500 m2/g and an outer surface area of 0.1-5 m2/g. |
