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

A method for preparing synthesis gas, the method comprising:
- supplying a pyrolysis gas oil (PGO) stream including a PGO discharged from a naphtha cracking center (NCC) process to a distillation tower;
- and
- supplying a lower discharge stream from the distillation tower and a pyrolysis fuel oil (PFO) stream including a PFO discharged from the naphtha cracking center (NCC) process to a combustion chamber for a gasification process as a feed stream to obtain synthesis gas,
- wherein a ratio of a flow rate of an upper discharge stream from the distillation tower to a flow rate of the PGO stream supplied to the distillation tower is 0.04 to 0.23.
