9 Claims

1. 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

producing lump coke by carbonizing the raw coal at 800 to 1300° C.
