Essay / Carbon Dioxide Essay - 530
INTRODUCTION: Carbon dioxide (CO2) is a key global warming gas that is proposed to have a direct link to global climate change [1, 2]. Therefore, there is growing interest in developing technologies to efficiently capture and sequester large quantities of CO2. An efficient and economical capture material is required to capture and separate CO2 produced during various industrial processes. There are four potential sources of carbon dioxide emissions; industrial processes, fossil fuel power plants, decarbonization (production of hydrogen from carbon-rich feedstocks) and transportation [3]. Among the sources of carbon dioxide emissions, fossil fuel-fired power plants are ranked as the first potential source. Fossil fuels provide 81 percent of the world's commercial energy supply [4]. The consumption of fossil fuels produces nearly 30 Pg (petagram) of carbon dioxide each year. About three-quarters of the increase in atmospheric carbon dioxide is attributed to the burning of fossil fuels [5]. At present, adsorption is widely accepted in environmental and industrial treatment applications. ...
