This paper investigates the application of photocatalytic oxidation in packed bed reactors as an innovative technology for the removal of volatile organic compounds (VOCs) from air. VOCs are present in urban and industrial areas, and their effective removal is becoming crucial for the protection of human health and the environment. Photocatalytic oxidation utilizes light energy to activate a catalyst, most commonly titanium dioxide (TiO2), which then decomposes VOCs into less harmful compounds, thereby improving air quality. The paper provides an overview of the key aspects of VOCs, including their definition, classification, and impact on the environment and health. Particular attention is paid to benzene, one of the most toxic volatile compounds which significantly contributes to air pollution. The paper also presents the basic principle of photocatalytic oxidation, the properties of photocatalysts, and their immobilization on fillers such as recycled rubber. The application of this technology in the removal of VOCs from air and the effectiveness of different fillers in the process are analysed. Technological advancements have enabled the development of reactors that optimize the contact between light, catalyst, and pollutants, thereby increasing the efficiency of the process. Packed bed reactors, containing materials such as glass or plastic beads, provide structural support for photocatalytic materials and allow the creation of larger surface areas for the reaction. Understanding the dynamics of the photocatalytic process in utilised reactors, including light distribution, airflow, and interactions between the catalyst and pollutants, is crucial for optimizing and achieving the success of photocatalytic degradation. Given the growing concern of humanity about air quality and increasingly strict regulations regarding pollutant emissions, photocatalytic oxidation in packed bed reactors offers a sustainable solution that can significantly reduce VOC concentrations in exhaust gases and industrial emissions. The introduction of this technology requires a thorough understanding of the chemical and physical processes involved in the photocatalytic reaction, as well as the knowledge of the design and operational characteristics of packed bed reactors. Therefore, it is important to study all the aspects of this technology, from laboratory experiments and modelling to commercial application and environmental impact.
