摘要: 1.本文分别研究了在1150,1200,1250和1300℃时,Cu-S 系熔体与氢反应的动力学.得到如下动力学方程式:富硫单相区 u_S=0.717 exp[-(53.137)/(RT)](S%-α)~2p_(H_2)~(1/2)+常数不熔合分层区 u_S=0.531 exp[-(67.259)/(RT)]p_(H_2)~(1/2)富铜单相区 u_S=44.6 exp[-(146.720)/(RT)]p_(H_2)~(1/2)·S%+常数Cu-S 系和氢的脱硫速度主要取决于熔体中硫的浓度,但不熔合分层区除外.在一定的温度和氢分压下,反应速度大小的次序为:u_S(h)>u_S(m)>u_S(l)2.脱硫反应和 Cu-S 相图结构关系中 S 和 Cu 的活度数学模型方程式为:富硫单相区：熔合分层区(b=1.2-19.8%S富铜单相区(0

Abstract：1.The kinetics of reaction between Cu_2S-Cu system melts and H_2 has been studied at 1150,1200,1250 and 1300℃ respectively.Their equations are: for S-rich single phase,u_S=0.717 exp(-(53.137)/(RT))(S%-α)~2p_(H_2)~(1/2)+const. for misc.gap,u_S=0.531 exp(-(67.259)/(RT))p_(H_2)~(1/2) For Cu-rich phase,u_S=44.6 exp(-(146.720)/(RT))p_(H_2)~(1/2)·S%+const. These desulphurization rate are mainly dependent upon the S concentration of melt except the miscible gap.At constant temperature and H_2 partial pressure,their sequence is u_(S(h))>u_(S(m))>u_(S(l)). 2.The mathematic model of desulphurization and activities of S and Cu in relationship to the structure of Cu-S phase diagram are: for S-rich single phase (α=19.81-19.61%S), (?)=A(constant) for miscible gap (b=1.2-19.8%S), (?)=0 for Cu-rich single phase,(0
