The Looping Sulfide Oxidation process for copper production removes sulfur in a single step while using copper oxides (Cu 2 O and CuO) as oxidizing agents to either replace or augment oxygen (O 2) from natural air without producing a matte phase. Reference herein to copper oxide oxidizing agents include copper carbonates, sulfates and other ...

Read MoreThis paper presents a new solids looping process for capturing CO2 while generating hydrogen and/or electricity from natural gas. The process is based on the sorption enhanced reforming of CH4, employing CaO as a high temperature CO2 sorbent, combined with a second chemical loop of CuO/Cu. The exothermic reduction of CuO with CH4 is used to obtain the heat necessary for the decomposition of ...
