Применение карбоксильного катионита в качестве преформы для получения сферического катализатора

Abstract

The properties of the Tokheim-250 carboxylic cation exchange resin and its selectivity to Co2 + and Ni2+ ions are studied. The values of the sorption capacity for the Co2+ and Ni2+ ions, the effective ionization constant of the functional groups (pKa = 6,59), and the values of the ion distribution coefficients (~ 103) are calculated. Founded that the selectivity of the sorption of Co2+ increased to Ni2 +. In this regard, carboxylic cation exchanger Tokem-250 samples with nickel ion was used to create spherical catalysts. The developed spherical materials have catalytic activity in the reactions of deep and partial oxidation of n-heptane.
