In the second stage, the syngas is converted into light hydrocarbons using one of three main processes: FischerTropsch synthesis, methanol synthesis with subsequent conversion to gasoline or petrochemicals, and methanation. Of the three methanol synthesis reactions, the latter is the well-known water-gas-shift (WGS) reaction. Since the H 2 /CO ratio in syngas from todays slagging gasifiers typically ranges from 0.3 to 1, extensive water gas shift is required to meet the stoichiometric H 2 /CO ratio of 2 for full conversion to methanol. In fact, besides multiple gasifier options and configurations, the liquid fuel synthesis component itself can be approached multiple ways: methanol-to-gasoline or Fischer-Tropsch (FT) synthesis, to name the two most important. The temperature and pressure can be controlled at 250300C and 50150 bar (515 MPa), respectively.
