Abstract
Provided is a method for preparing synthesis gas, and more particularly, a method for preparing synthesis gas including: mixing 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 produce a mixed oil stream (S); and supplying the mixed oil stream to a combustion chamber for a gasification process to obtain synthesis gas (S), wherein a ratio of a flow rate of the PGO stream in the mixed oil stream to a flow rate of the mixed oil stream is 0.01 to 0.3.
