Abstract

A method to upgrade virgin and partially hydrogenated asphaltic residual oils by utilizing hot, high velocity combustion gas jets to rapidly atomize and heat the residual oil, maintaining the reactant temperature required to achieve the desired residual oil conversion with the minimum practical residence time, rapidly separating vapor and liquid reactants, and rapidly cooling the vapor and liquid products. The minimum required temperature and practical residence time are used for the production of deasphalted oil and asphaltene products with minimum degradation due to thermal cracking. The maximum conversion of residual oil may be substantially increased by combining a portion of the heavy oil product with the residual oil feed and partially hydrogenating this mixture.

Claims

AMENDED CLAIMSReceived by the International Bureau on 23 December 2008 (23.12.08)Having thus described the invention, what I claim is:
1. A method for upgrading asphaltic residual oil comprising:
a) producing a combustion gas jet by expansion of a combustion gas through a convergent-divergent nozzle
b) contacting said asphaltic residual oil with said combustion gas jet to obtain an adiabatic temperature between 500 and 850° C;
c) separating a vapor phase and a liquid phase formed by said contacting using an inertial separator; and
d) cooling said vapor phase and said liquid phase products to form light and heavy oil products with reactant residence time above 4250C less than 400 milliseconds.
2. The method as claimed in claim 1 wherein said cooling is to a temperature less than 400° C.
3. The method as claimed in claim 1 wherein said asphaltic residual oil feed has an apparent viscosity less than 1000 cP.
4. The method as claimed in claim 1 wherein said asphaltic residual oil is at a temperature of about 100 to about 4250C prior to contacting said combustion gas jet.
23
5. The method as claimed in claim 1 further comprising hydrotreating said asphaltic residual oil by contacting with a homogeneous catalyst prior to contact with said combustion gas.
6. The method as claimed in claim 1 wherein said homogeneous catalyst is a molybdenum sulfide catalyst.
7. The method as claimed in claim 1 wherein said hydrotreating is performed in a hydrotreating reactor selected from the group consisting of an ebullated, upflow, and fixed bed hydrotreating reactor.
8. The method as claimed in claim 1 wherein hydrogen is added to said asphaltic residual oil.
9. The method as claimed in claim 1 wherein said hydrogen is added to said asphaltic residual oil at about 100 to about 1500 standard cubic feed per barrel of asphaltic residual oil.
10. The method as claimed in claim 1 wherein said hydrogen is added to said asphaltic residual oil at about 150 to about 1000 standard cubic feed per barrel of asphaltic residual oil.
11. The method as claimed in claim 1 wherein said combustion gas jet is formed by reacting an oxidant with a fuel.
12. The method as claimed in claim 1 wherein said oxidant is selected from the group consisting of air, oxygen-enriched air and substantially pure oxygen.
13. The method as claimed in claim 1 wherein said fuel is selected from the group consisting of carbon monoxide, hydrogen, gaseous hydrocarbons and mixtures thereof.

26. The method as claimed in claim 1 wherein the inertial separator has a tapered section to generate inertial forces to accelerate the heavy oil to the heavy oil discharge conduit.
27. The method as claimed in claim 1 wherein the inertial separator wall is cooled to a temperature between 400 and 2000C.
28. The method as claimed in claim 1 where in the inertial separator wall temperature is controlled using a boiling liquid
29. The method as claimed in claim 1 wherein a liquid distillate quench is used to rapidly cool heavy oil.
