Controlling the synthesis gas composition of a steam methane reformer

摘要

An improved, economical alternative method to supply steam and methane to a steam methane reformer (SMR) is accomplished by a combination of procedures, wherein product gas from a steam hydro-gasification reactor (SHR) is used as the feedstock for the SMR by removing impurities from the product stream from the SHR with a combination of autothermai reforming, condensation removal and gas cleanup procedures that operates substantially at process pressures and at a temperature above the boiling point of water at the process pressure, is located between the SHR and SMR. In another embodiment, a method is provided for controlling the H2/CO syngas ratio obtained from a steam methane reformer (SMR) by adjusting the hydrogen feed and the water content of feedstock into a steam hydro-gasification reactor that supplies the SMR.
