对陕西韩城等矿区现主采的石炭 -二叠系煤层——— 2 # ,3# ,5# ,1 1 # 煤的全硫、无机硫、有机硫和硫酸盐硫的含量、分布进行了研究。 2 # (下二叠统 )煤的平均含硫量为 0 .47% ;3# 煤(下二叠统 )的平均含硫量为 0 .63% ;5# 煤 (上石炭统 )的全硫平均含量为 2 .2 1 % ,煤中的硫主要为无机硫 ;1 1 # 煤 (上石炭统 )的全硫平均含量为 3.99% ,主要为有机硫 ,有机硫的含量占全硫含硫的 55%～ 90 % .同时 ,对煤的含硫量与煤中灰成分等的相关关系进行了分析研究。
The content, distribution of total sulfur, inorganic sulfur, organic sulfur and sulfate sulfur of the 2 #, 3 #, 5 #, 1 1 # coal currently being collected in the coal mining area of Hancheng, Shaanxi, Study. The average sulfur content of 2 # (Lower Permian) coal was 0.47%; the average sulfur content of No 3 # coal (Lower Permian) was 0.63%; and the total amount of 5 # coal (Upper Carboniferous) The average sulfur content was 2.21%. The sulfur in coal was mainly inorganic sulfur. The average sulfur content in 11 # coal (Upper Carboniferous) was 3.99%, mainly organic sulfur. The content of organic sulfur accounted for total sulfur content 55% ~ 90% of sulfur.At the same time, the relationship between sulfur content in coal and ash content in coal was analyzed.
