Purpose: Syngas through water gas shift reactions connects multiple reasonings to the establishment and production of different oil and gas related industries. The following synthesis gas analysis will begin with the explanation of the water gas shift reaction along with its Steam Reform reactor and Fischer-Tropsch processes. In most of the analysis the whole process of involvement of synthesis gas with water gas shift reactions will be discussed. Furthermore, the involvement of catalysts in processing techniques will be introduced. In reference to processing, the explanation will delve into the effects of high- and low-temperature displacement catalysts and their compositions. Regarding industrial environments, the main examples of the process will also be discussed, which includes the production of synthesis gas through multiple uses. A brief explanation in terms of economics, alternative uses and ecological effects through the respect of synthesis gas through water gas displacement reactions will also be discussed. Introduction: The water gas displacement reaction was first exposed and practiced by the Italian entrepreneur and physicist Fenice Fontana in 1780. Through the extension of the chemical and physical properties of gases, he used the WGSR to produce a production of hydrogen is economically advantageous. The reagents contained synthesis gas or water gas, carbon monoxide and hydrogen mixture. The WGSR was expanded in 1873 by Thaddeus S. C. Lowe, where he used the gas displacement reaction of water with high-pressure steam and coke gas to produce excessive amounts of hydrogen gas. Today, water gas shift reactions have been intertwined with synthesis gas to produce the same products, however, with increased demand with production increases due to catalyst involvement. Process: Demand for pure hydrogen is steadily increasing in the middle of the paper. .....–304D.R. Simbeck, A. D. Karp, and R. L. Dickenson.
