Solubility of Copper Oxides in Water and Steam
نویسندگان
چکیده
The solubility of cupric and cuprous oxides was measured in water over the range 25 to 350 °C in the presence of various chemical agents (NaOH, NH3, B(OH)3, H3PO4, (OHCH2)3CNH2, (OHCH2)3CN(OHCH2CH3)2, HF3CSO3, HNO3 and mixtures thereof), and in steam to 400 °C as a function of pressure. Large discrepancies exist between the various experimental studies, especially at high temperatures for cuprous oxide, where the current solubilities are orders of magnitude lower. The solubilities of both oxides in water are highly pH dependent, but are virtually pH independent in steam.

Role of Surface Precipitation in Copper Sorption by the Hydrous Oxides of Iron and Aluminum.
Isotherms were developed at pH 6.9 for adsorption (ADS) and coprecipitation (CPT) of Cu by hydrous oxides of Fe (HFO) and Al (HAO) to study the role of sorbate/sorbent ratio in metal cation removal. For low sorbate/sorbent conditions, HFO had a higher Cu retention capacity than HAO regardless of contact methodology. For either oxide, CPT was consistently more effective than ADS in removing Cu f...

Steam reforming of methanol (SRM) was investigated over copper-containing catalysts supported on four different oxides and mixed oxides: Cu/ZnO/Al2O3, Cu/ZrO2/CeO2, Cu/SiO2 and Cu/Cr2O3/Fe2O3. After observing slight differences in the way of catalyst aging and experimental exclusion of mass transport limitation effects, a detailed kinetic study was carried out at 493 K. The dependence of the re...
