摘要：

Asphaltenes from coal hydrogenation can be considered to be representative for the basic structural units of coal, owing to their thermal and chemical stability. The investigation of their properties and reactions leads to valuable structural and technical data of coals which are not easily obtainable from the coal itself. First results concerning cluster size, sulfur bonds and structural changes in coal oxidation are reported. © 1990.
