OSTI ID:7128523
Heavy direct coal liquefaction products are known to exhibit rapidly increasing viscosities upon prolonged exposure to oxygen. Small angle x-ray scattering has been used to monitor changes in the colloidal structure of a coal liquid subjected to accelerated aging under an oxygen atmosphere for a total period of eight weeks. The data are consistent with an agglomeration model for the formation of large colloidal size scattering centers which are partially responsible for the rapidly increasing viscosity of the coal liquid. 21 references, 2 figures.
