摘要
借助SEM和X 射线衍射等 ,研究Cu2 S酸性和碱性水浆高压氢还原过程。结果表明 ,两种体系的氢还原反应都可进行到一定程度 ,但还原机制可能不同。在Cu2 S或CuS的碱性水浆中添加适量ZnO时 ,Cu的转化率可分别达到 92 %和 85 %。
The direct hydrogen reduction of Cu 2S in acidic and basic slurries are investi ga ted by the help of SEM and X-ray diffraction. The results show that the reduct io ns proceed to a certain extent in the two systems, but the reduction mechanisms may be probably different. The reduction of Cu sulfides tends to completion whe n proper amount of ZnO is added into the basic Cu 2S or CuS slurry, and the tran sformations of Cu reach to 92% and 85%, respectively.
