Study on experimental analysis of CO2 reduction using CA CB catalyst by thermos catalytic gasification for fuel gas production

Abstract

With rapid industrial and commercial growth, a significant amount newlineof fossil fuel is used endlessly, causing detrimental environmental challenges. newlinecarbon dioxide (CO2) emissions, intensify climate change and hence newlinereducing/reusing them has been accorded top priority. In recent decades, the newlineamount of CO2 in the atmosphere has increased causing a significant impact on newlineclimate change of late the IPCC released a special report on implications related newlineto GHG emissions. UNFCCC is aimed at addressing climate change and newlineminimizing its hazardous impacts on the human climate system. To achieve newlinethis goal, the UNFCCC outlines several key objectives including stabilization newlineof GHG concentrations and mitigation of climate change by transition to low newlinecarbon technologies and promotion of sustainable development. CCU is a newlinesuccessful method for utilising carbon emissions as a source that can be reused newlineby capturing and converting CO2 into fuel gas and other hydrocarbons, which newlinereduces global warming and produces a carbon-neutral/negative atmosphere. newlineIn this context, the reduction of CO2 to carbon monoxide (CO) as newlinefuel gas is a key area for decarbonization in the energy sector. The reduction of newlineCO2 can be accomplished through thermal decomposition, thermo-catalytic newlinereduction, photo-catalytic reduction and electro-catalytic reduction. Among newlinethese, thermo-catalytic reduction adopting gasification technique is observed to newlinebe a promising one. Gasification process typically converts CO2 in to a burnable newlinegas (CO) under high temperature environment supplemented with carbon newline(Boudouard Reaction). In this study suitable reduction catalyst had been newlinesynthesized with an objective towards minimizing the temperature required for newlineconversion of CO2 to CO. Seven (4 from alkali metals, 2 from alkaline earth newlinemetals and 1 from transition metal) different types of reduction catalysts newlinesupported with carbon in 3 geometries (bead, sieve, granules) had been newlineidentified for the experimental analysis. newline
