Abstract
Official abstract text for this publication.
A novel composition is provided that incorporates the residual solids from solvent deasphalting to make a high value asphalt product. A process for making the asphalt composition is also provided. A first portion of heavy oil or another feedstock can be deasphalted using propane deasphalting or another suitable deasphalting process. This generates a solvated fraction and an insoluble deasphalting residue. The deasphalting residue is then added to a second portion of heavy oil, such as a second portion of the same type of heavy oil that was used as feedstock in the solvent deasphalting. The mixture of deasphalting residue and heavy oil results in a novel dispersion that is suitable for use as an asphalt. Optionally, an additive such as an alkyl substituted aromatic sulfonic acid can be added to the composition to further improve the asphalt properties.
First claim
Opening claim text (preview).
What is claimed is: 1. An asphalt composition, comprising: a mixture of a first heavy oil fraction and a deasphalting residue from solvent deasphalting of a second feedstock fraction, the first heavy oil fraction having a T5 boiling point of at least 350° C., the second feedstock fraction having a T5 boiling point of at least 350° C., wherein a weight ratio in the mixture of the first heavy oil fraction relative to the deasphalting residue is from 30:70 to 70:30, and further com…
