To manufacture a coal water slurry(CWS) which is combustible without dehydration, a series of nonionic surfactants was synthesized from polyethylenimine (PEI nonionic SAA). Their abilities for the preparation of highly loaded CWS were examined using Tatung coal powder.
The main findings are as follows.
1) Using PEI nonionic SAA, Tatung coal CWS of high coal content (up to 69%) can be prepared (Table 1).
2) When the molecular weight of polyethylene oxide per each side chain becomes about 5000, coal content in CWS becomes maximum (Fig.1).
3) Abilities of O-[poly(oxyethylene)] polyhydric a lcohol to make highly loaded CWS are low (Fig.2).
