Abstract
The present invention relates to a method for upgrading heavy oil by using byproducts of coke production, and particularly provides a method for upgrading heavy oil comprising the steps of: a) mixing heavy oil with byproducts of coke production to produce a mixed liquid: and b) subjecting the mixed liquid to pyrolysis, the method allowing reduction of the amount of coke generated and thus being economical and effective.
Claims9
A method for upgrading heavy oil using byproducts of coke production, the method comprising:
- a) mixing heavy oil with byproducts of coke production to produce a mixed liquid;
- and
- b) subjecting the mixed liquid to pyrolysis,
- wherein the byproducts of the coke production are liquid byproducts generated in producing lump coke, and
- wherein the producing of the lump coke includes:
- preparing raw coal by crushing and drying coal;
- and
