The experimental study on desulfurization of mixture of coal and poplar powder through pyrolysis in oxidative atmosphere;

煤与杨木粉在氧化性气氛下低温热解脱硫的实验研究

The raw Heshan coal was pyrolyzed in a fixed-bed reactor in oxidative atmosphere to examine the sulfur removal efficiency and the volatilization content.

在氧化性气氛中采用固定床反应系统对合山原煤进行了热解脱硫效果考察。

Experimental results show that the fixation proportions of chromium, nickel, copper and arsenic would increase with the elevation of their melting and boiling points under oxidizing atmosphere.

结果表明,在氧化性气氛下重金属Cr、Ni、Cu、As的固溶率与其熔沸点呈正相关,固溶率依次为:Cr>Ni>Cu>As;低沸点重金属Pb、Cd、Hg等在熔融过程中均有很高的挥发性,由于熔融时Zn易形成Zn2SiO4、ZnSiO3和ZnAl2O4等不易挥发的化合物,故其挥发率较低。
