Research Abstract

Huge amount of coal is now imported from Australia. For the stable and safe supply of energy, more sophisticated coal utilization techniques should be developed. The preparation and utilization techniques for the coal slurries have been extensively developed in recent years. In particular, the practical use of CWM (Coal Water Mixture) is available at the present stage. The use of CWM has great advantage to reduce the cost for the transportation of coal from Australia to Japan, because CWM can be transported by pipeline and slurry tanker as a fluid fuel. Also, this technology is of particular significance in view of the "environmental friendly" characteristics. The purposes of this collaboration program are described as follows.
1. Development of effective dispersing additives and stabilizing additives.
The use of suitable dispersing additive can increase in the coal concentration and cause the decrease of CWM viscosity.
The stabilizing additive is necessary to prohibit the sedimetation of coal particles during the transportation and storage of CWM.
2. Investigation of the process development in the preparation of coal slurries.
The studies on the pulverization and pretreatment of coal slurries are valuable for the upgrading the CWMs from various kind of coal.
3. Rheological measurements of CWM and modeling the thixsotropic behavior of coal slurries.
Rheological study on suspensions CWM is necessary to understand the complex behavior of CWM.
During the program, Japanese Professors from Universities of Yamaguchi and Kagoshima visited Australia for collaborative research with Australian colleagues. Also, researchers from Universities of Newcastle, Melbourne, Monash and RMIT in Australia visited Japan during 1993 and 1994. The results of this collaborative research have been published as more than twenty papers in many journals and conference proceedings. New aspect of the CWM technology has been obtained to solve the difficult problems in the practical use of CWM.
