Abstract
The present invention is directed to active compositions, such as adsorbents and catalysts, which comprise cuprous compounds dispersed on amorphous oxide or carbon macroporous supports. The compositions are prepared by impregnating cupric compounds on pretreated supports with the aid of an aqueous solution of an ammonium salt of a di- or polycarboxylic acid dispersant, such as ammonium citrate, followed by activation of the cupric compound or reduction of the cupric compound to the corresponding cuprous compound. Methods of synthesis and processes utilizing the compositions are also disclosed.
