Abstract
Provided is a method for preparing synthesis gas, and more particularly, a method for preparing synthesis gas including: supplying a pyrolysis fuel oil (PFO) stream including a PFO and a pyrolysis gas oil (PGO) stream including a PGO discharged from a naphtha cracking center (NCC) process to a distillation tower as a feed stream (S10); and supplying a lower discharge stream from the distillation tower to a combustion chamber for a gasification process to obtain synthesis gas (S20), wherein the PGO stream is supplied to an upper end of the distillation tower and the PFO stream is supplied to a lower end of the distillation tower.
