| 摘 要： | 对生物－非生物煤炭脱硫的原理、菌种及操作条件等问题进行了探讨和实验研究。实验结果表明非生物－乳化技术与生物脱硫技术结合应用，大大提高了脱硫效率。在２－３ｄ内煤炭黄铁矿硫去除率为５３．２％，总硫去除率为３２．７％，而且改变煤粒度或反应条件均会改变总硫去除率，最高可达４７％（２ｄ）。

| Abstract: | A study was made on the principles of a combined bacteria-emulsion process for removing sulfur from coal, the species of bacteria used for this purpose, and the operation conditions of this process. The results show that a combination of emulsification technology with microbial desulfurization technology has substantially improved the efficiency of desulfurization. During a period of 2 or 3 days, 53.2% of pyrite were removed from coal at a total desulfurization rate of 32.7%. The sulfur removal varies with the changes in the size of coal particle and the conditions of reaction,with a maximum removal of up to 47% in 2 days. |
