Mineral fuel is the primary energy source in the world today, thereinto coal resource holds in store more than 75 percent in the total energy source. During coal's utilized, nocuousness matter expels into environment through all kings of method and works serious environmental pollution. Desulphurization has become one of primary objects of cleaning coal. At present, there are some primary problems of removing sulfur from coal. It is the size of coal is too small, the time of removing sulfur is too long, the technology is too complicated and the investment is much expensive etal.
中文题名燃煤微生物预处理浮选脱硫的试验研究副题名外文题名 Study on microbial pretreatment and floatation desulphurization in coal 论文作者周志付导师王英敏魏德洲教授学科专业安全技术及工程研究领域\研究方向学位级别博士学位授予单位东北大学学位授予日期2002 论文页码总数99页关键词燃煤微生物预处理-浮选脱硫煤炭脱硫馆藏号BSLW /2003 /X701 /2 矿物燃料是当今世界的主要能源,其中煤炭资源蕴藏量占总能源的75%以上,在煤的利用过程中,有害物质以各种方式排入周围环境,造成了严重的环境污染,因此脱硫已成为洁净煤技术的主要目标之一,而目前煤中硫的脱除存在的主要问题是:煤粉太细,脱硫时间长、技术复杂,投入费用太高等。

Two times hydrolyzation of Fe~(3+) and Cr~(3+) was firstly pointed out in the process of pillar preparation with hydrothermal method. In order to improve the thermal stability, Fe/Cr-Si-pillaring agent solution was synthesized by hydrolyzing Fe~(3+) and Cr~(3+) solution on the surface of silica sol, and Fe/Cr-Si-pillared montmorillonite (Fe/Cr-Si-PILM) was prepared with conventional method and hydrothermal method. Because the technical innovation of preparation is the best way to improve the PILM properties, two novel methods (Microwave method and Ultrasonication method) have been studied to synthesize Fe/Cr-PILM.In order to expand PILMs new application in the field of coal conversion, catalytic activity of Fe/Cr-Si-PILM catalyst in LongKou lignite and ShenHua coal residue liquefaction was discussed and characterized in the last part of this paper.

Calcium montmorillonite was prepared by purifying LeXi bentonite with wet method two times. After purification, sodium modification of Ca-M was studied. A series of Fe/Cr-pillared montmorillonites were prepared with conventional method using sodium montmorillonite as experimental materials, and synthesis condition of Fe/Cr-PILM was studied and optimized. In order to shorten the preparation cycle of PILM by overleaping the step of sodium modification of Ca-M, the pretreatment technique for Ca-M has been pointed out for the first time. A series of PILMs were prepared with hydrothermal method using pretreated Ca-M as starting materials, which show that pretreatment of Ca-M is feasible.
