| 中文摘要 |
| 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)。 |
| 英文摘要 |
| 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. |
