Abstract
Provided is a method for preparing synthesis gas, and more particularly, a method for preparing synthesis gas including: supplying a cracked gas stream discharged from a cracking furnace of a naphtha cracking center (NCC) process to a gasoline fractionator, separating a side discharge stream from the gasoline fractionator using a first stripper, and separating a lower discharge stream from the gasoline fractionator using a second stripper, wherein a mixed oil stream of a PGO stream and a PFO stream formed by controlling a flow rate of each stream are used.
