Biomass valorization: Developing novel methods f​​or pretreatment and biopolymer (bioplastic) synthesis

Principal ​Investigator: Dr. Debraj Bhattacharyya (Civil Engg.), Prof. Tarun K Panda (Chemistry), and Dr. Debaprasad Shee (Chemical Engg.)

The Greenko School of Sustainability at IIT Hyderabad is offering a Ph.D. project to develop a novel, environmentally friendly, and economically viable deep eutectic solvent (DES)-based pretreatment method for resource recovery from lignocellulosic biomass. The goal is to effectively separate lignin and cellulosic components and recover the lignin for bioplastic film production. The research aims to establish a method for resource recovery from lignocellulosic biomass, including the development of a novel DES-based, environment-friendly, and economically viable pre-treatment method, effective separation of lignin and cellulosic components, and recovery of the lignin component in the form of bioplastic films. The project aims to improve the efficiency of resource recovery from lignocellulosic biomass.

Proposed Outcomes 

  • A DES that is effective for pretreating lignocellulosic biomass and is less expensive than the commercially available DES. 
  • A simple method to synthesize DES at site. 
  • An optimized pretreatment method that can be used for pilot-scale demonstration in the future. [Pilot-scale demonstration is not within the scope of this project]. 
  • Technology Readiness Level 4 (TRL 4) will be achieved. 
  • A bio-based polyol derived from lignin through esterification process and its product (bio-polyol) yield enhancement.

Electric Swing Adsorption for Carbon Capture and Lithium Recovery

Principal ​​Investiga​tor ​Dr. Deepu J Babu, Department of Materials Science And Metallurgical Engineering & Climate Change

Introduction :​ Conventional sorption technology for the separation of gases relies on temperature or pressure swings to modulate the adsorbate-adsorbent affinity. A significant amount of energy is consumed in the sorption-regeneration process. Electric swing adsorption or in more general electrochemical swing adsorption, is an emerging area of research, where adsorption and desorption can be brought about by switching the polarity. Being an isothermal process with no cyclic pressurizing or depressurizing, a significant amount of energy can be saved in the capture process. 

Objectives

  • CVD synthesis of 2D materials like graphene and carbon nitride ·       
  • Gas and ion adsorption studies on 2D materials ·       
  • Electric swing adsorption (ESA) based carbon capture ·    
  • Electric swing lithium recovery 

Proposed Outcomes 

  • CVD synthesis of graphitic carbon nitride. 
  • Development of technology for measuring adsorption on 2D films·       
  • Development of an electrochemical CO2 capture setup· 
  • Electric swing adsorption-based novel technology for carbon capture·  
  • Electric swing adsorption-based lithium recovery Performance comparison of developed technology against the existing/commercially available technology.
