陕西韩城寒武系白云岩和石灰岩固硫试验

SULFUR ABSORPTION EXPERIMENT USING CAMBRIAN DOLOMITE AND LIMESTONE OF HANCHENG AREA,SHAANXI PROVINCE

摘要: 选用韩城7个分别采自于寒武系白云岩和石灰岩的样品,以10%和25%为基准,加入韩城的高硫煤中,进行固硫试验。研究表明:中、下寒武系白云岩固硫率为10%~15%,石灰岩的固硫率为15%~26%,上寒武统下部白云岩的固硫率为30%~47%。上寒武统中上部的白云岩固硫率为10%~20%。岩石中白云石和方解石的含量相当时,白云岩的固硫率高于石灰岩5~10个百分点。

Abstract: For sulfur absorption experiment 7 samples were individually collected from Cambrian dolomite and limestone of Hancheng area,and mixed to highsulfur coal on 10% and 25% basis.Results indicated that the sulfur absorption rate is 10%~15% for mid and early Cambrian dolomite;15%~26% for mid and early Cambrian dolomite;30%~47% for lower part of late Cambrian dolomite;10%~20% for middle and upper part of late Cambrian dolomite.The sulfur absorption rate of dolomite is 5~10 percent larger than that of limestone,when the content of dolomite is similar with the content of calcite.
