Reduction of two wheeler exhaust emissions by Adsorption

Chemical Engineering

The increasing prevalence of two-wheeler vehicles has led to a significant rise in air pollution, primarily due to their exhaust emissions. This project explores the potential of adsorption technology to mitigate the harmful pollutants emitted from two-wheeler exhaust systems. Adsorption is a process where molecules adhere to the surface of a solid or liquid, making it an effective method for capturing and reducing harmful gases such as carbon monoxide (CO), hydrocarbons (HC), and nitrogen oxides (NOx). In this study, various adsorbent materials, including activated carbon, zeolites, and metal-organic frameworks (MOFs), were evaluated for their efficacy in adsorbing exhaust pollutants. The experimental setup involved a simulated exhaust system where emissions were passed through chambers containing different adsorbents. Key performance indicators such as adsorption capacity, breakthrough time, and regeneration capability were assessed. The results demonstrated that activated carbon exhibited the highest adsorption capacity for hydrocarbons and carbon monoxide, while zeolites were more effective in capturing nitrogen oxides. MOFs showed promising performance across all pollutant categories, indicating their potential as a versatile adsorbent material. Furthermore, the study investigated the regeneration techniques to restore the adsorptive capacity of the materials, ensuring sustainability and cost-effectiveness of the process. The implementation of adsorption-based emission control systems in two-wheelers could significantly reduce the environmental impact of these vehicles, contributing to improved air quality and public health.
