Abstract

The relationships between the chemical constitution of the petroleum feedstocks and the mesophase development were investigated. A range of coker feedstocks that were characterized by solvent fractionation, elemental analysis, and FT-IR were carbonized in conventional tubing bomb reactors. The solid carbonization products were examined by polarized-light microscopy. In general, a direct relationship was observed between the degree of aromaticity of the feedstocks and the extent of mesophase development. The separate carbonization of the asphaltene and maltene fractions of the feedstocks indicated that the asphaltenes dominated in determining the optical textures of the semicokes produced from the petroleum feedstocks.
