Abstract
The present invention relates to a method for converting heavy oil by means of high dispersion of asphaltenes, comprising the steps of: preparing a mixture by mixing an amphiphilic additive and the heavy oil; and performing a hydrogenation reaction on the mixture, wherein the amphiphilic additive comprises both a polar group and a nonpolar group.
Claims7
A method for converting heavy oil by means of high dispersion of asphaltenes, comprising the steps of:
- preparing a mixture by mixing an amphiphilic additive and the heavy oil;
- and
- converting the heavy oil through performing a hydrogenation reaction on the mixture, wherein the amphiphilic additive comprises both polar and non-polar functional group,
- wherein the amphiphilic additive comprises a product obtained from a bottom stream in which waste oil is distilled;
- the method further comprises obtaining a hydrogenation reaction catalyst which comprises the bottom stream, wherein the hydrogenation reaction is performed using the hydrogenation reaction catalyst, and the waste oil comprises at least one metal component among molybdenum, iron, zinc, and copper, wherein the bottom stream comprises 50 ppm to 3,000 ppm of molybdenum and wherein the bottom stream further comprises 100 ppm to 5,000 ppm of iron, 1,000 ppm to 5,000 ppm of zinc, and 50 ppm to 5,000 ppm of copper;
- and
- the method further comprises mixing at least one among Group VIII(b), Group VI(b), Group 11(b), and Group I(b) transition metals, Group VI(a), Group V(a), Group VII(a), and Group IV(a) elements, and compounds comprising the same in the bottom stream, wherein the mixing is performed such that the amount of molybdenum is adjusted to be in an amount of 150 ppm to 5,000 ppm in the hydrogenation reaction catalyst and wherein sonication is applied during the mixing.
