There are several routes for syngas

There are several routes for syngas generation from any carbonaceous feedstock. All technologies used for synthesis gas technologies are based either on steam reforming, partial oxidation, or a combination of the two as in Autothermal Reformer (ATR) [1]. The preparation of synthesis gas is one of the most capital intensive parts of a GTL-complex and may account for 30% to 50% of the total investment including cryogenic Air Separation Unit (ASU). The main reason for this high estimate is the high cost of ASU. ATR has become the state-of-the-art synthesis gas production technology for Fischer-Tropsch applications [2]. ATR is a relatively simple piece of equipment with a burner and a catalyst bed in a brick-lined pressure vessel [3]. In almost all GTL plants that utilize ATR, oxygen is used as oxidant, as in Oryx GTL plant in Qatar. Oxygen-blown ATR has also been commercially used in methanol synthesis [4] and is the preferred technology for large-scale GTL plants
