Some thoughts on the organic structure of bituminous coal [electronic resource]
Our current operating hypothesis is that coal consists of a cross linked macromolecular network of high aromatic clusters held together by linkages which include ethers and methylene groups. These clusters are arranged like beads on a string with 3 to 5 beads between branch points. Coal can be liquf...

| 520 | 3 | |a Our current operating hypothesis is that coal consists of a cross linked macromolecular network of high aromatic clusters held together by linkages which include ethers and methylene groups. These clusters are arranged like beads on a string with 3 to 5 beads between branch points. Coal can be liqufied most readily by cleaving the links between the clusters. Doing chemistry on the clusters in the whole coal is very difficult because of the problems of getting to the clusters by reagents. It is fortunate that the linkages between clusters are quite reactive. But even with this, it is clear that coal liquefaction is a formidable chemical problem. There is much wisdom is Sternberg's suggestion that the chemistry of the freed clusters (pre-asphaltenes) be developed. Our model indicates that the chemistry which results in freeing the clusters from the network also should be explored and broadened. | |
