Development of reaction kinetics model for the production of synthesis gas from carbon dioxide (Dry methane reforming)

Increasing problems related with climate change and global warming has lead Carbon Dioxide reducing technologies that have receive many attentions. Carbon Dioxide has been identified as the most major greenhouse gas (GHGS) arising from anthropogenic activities. It is very important to reduce anthropogenic Carbon Dioxide emissions in order to counteract global warming. This reaction has very important environmental implications since both Methane and Carbon Dioxide that dominantly produced from municipal solid waste (MSW) contribute to the greenhouse effect. Converting these gases into a valuable feedstock may significantly reduce the atmospheric emissions of Methane and Carbon Dioxide . Due to this condition as develop by past researcher, the efficient commercial production of syngas or synthesis gas (a mixture of Hydrogen and Carbon Monoxide ) is gaining significant attention and consideration worldwide as it is a versatile feedstock that can be used to produce a variety of fuels and chemicals such as Methanol, Fischer-Tropsch fuels, Hydrogen , Ethanol and Dimethyl Ether (DME). This mixture of Hydrogen and Carbon Monoxide can be produced by natural gas reaction which is Dry Methane reforming between Carbon Dioxide and Methane . The Dry Methane Reforming reaction mechanism is considered quantitatively with four reactions which are Carbon Dioxide (CO2) reduction by Methane (CH4), Reverse Water Shift Gas (RWSG), Carbon Deposition and Carbon removal by a reverse Boudourd reaction. Hence, in this paper we present a comprehensive review on the characteristics of Dry Methane Reforming mechanism that can be used as basic references for future case review. Modeling and simulation of the reforming behavior of mixture Carbon Dioxide and Methane was introduced. The Dry Methane Reforming (DMR) process was simulated using MATLAB simulation software. The stimulated data were evaluated and validated with the previous literature review. A detailed simulation studies is used to identify the essential characteristics of reaction mechanism of Dry Methane Reforming (DMR). The results showed that inlet gas flow in gas phase effect has significant effect to the reactions whereas inlet molar composition ratio of the reactions was found to have no significant effect on the mechanism of Dry Methane Reforming.
