Abstract
Provided is a method for preparing synthesis gas and aromatic hydrocarbons, and more particularly, a method for preparing synthesis gas and aromatic hydrocarbons including: supplying a pyrolysis fuel oil (PFO) stream containing PFO and a pyrolysis gas oil (PGO) stream containing PGO to a distillation tower as a feed stream (S10), the PFO stream and the PGO stream being discharged in a naphtha cracking center (NCC) process; and supplying a lower discharge stream from the distillation tower to a combustion chamber for a gasification process and supplying an upper discharge stream from the distillation tower to a BTX preparation process (S20).
Claims11
A method for preparing synthesis gas and aromatic hydrocarbons, the method comprising:
- supplying a pyrolysis fuel oil (PFO) stream containing PFO and a pyrolysis gas oil (PGO) stream containing PGO to a distillation tower as a feed stream (S10), the PFO stream and the PGO stream being discharged from a naphtha cracking center (NCC) process;
- and
- supplying a lower discharge stream from the distillation tower to a combustion chamber for a gasification process to obtain synthesis gas and supplying an upper discharge stream from the distillation tower to a preparation process of one or more of benzene, toluene, and xylene (BTX preparation process) to obtain aromatic hydrocarbons (S20),
- wherein a ratio of a flow rate of the upper discharge stream from the distillation tower to a flow rate of the feed stream to be supplied to the distillation tower is 0.01 to 0.2.
