Table Of Contents
- The project is the construction of fluidised bed reactor. After a detailed research mild steel was chosen as the material of construction based on its inherent properties. The construction process entitles the marketing out of the sheet to the specified dimensions. This was followed by center punching and cutting. The sheets are then joined together after rolling by welding. Finally, surface treatment like painting was carried out to give it a brighter colour and durable property.

Thesis Abstract
Abstract
Fluidized bed reactors have gained significant attention in various industries due to their versatility and efficiency in carrying out a wide range of chemical reactions and processes. This research project focuses on the construction of a fluidized bed reactor for the purpose of investigating its performance in specific applications. The design and fabrication of the reactor system involve considerations of key parameters such as bed material, gas flow rate, temperature control, and heat transfer mechanisms. The fluidized bed reactor is being constructed using high-quality materials that can withstand the operating conditions and ensure the safety and reliability of the system. The reactor design includes features such as a distributor plate for uniform gas distribution, a heating system for temperature control, and instrumentation for monitoring and controlling process variables. The construction process also involves testing and calibration procedures to validate the performance of the reactor before actual operation. The research project aims to evaluate the performance of the fluidized bed reactor in carrying out catalytic reactions, gas-solid reactions, and other processes of interest. The reactor will be tested under various operating conditions to study its behavior and efficiency in different applications. Performance parameters such as conversion rates, reaction kinetics, and heat transfer characteristics will be measured and analyzed to assess the effectiveness of the reactor design. In addition to performance evaluation, the research project also considers the scalability and potential industrial applications of the constructed fluidized bed reactor. The findings from this study will provide insights into optimizing the reactor design for specific processes and identifying opportunities for commercial utilization. The practical implications of using fluidized bed reactors in industries such as petrochemicals, pharmaceuticals, and environmental engineering will be discussed based on the experimental results and analysis. Overall, the construction of the fluidized bed reactor and the subsequent performance evaluation represent a significant contribution to the field of chemical engineering and reactor design. The research outcomes will advance the understanding of fluidized bed technology and its applications, leading to potential improvements in process efficiency, energy savings, and environmental sustainability.
