Abstrakt: In the example of x-ray structural investigation of petroleum asphalts and an oil containing an additive, feasibility has been demonstrated for studying disperse petroleum systems by means of the x-ray method. Large-scale x-ray scattering has been used to determine the aromaticity factor and structural parameters of the asphalts. Small-angle x-ray scattering has been used to establish that all the asphalts contain particles in the smallest size range with a quasispherical shape, and that the larger particles represent associates made up of these smallest particles.
