Connecting Science and Technology for a brighter tomorrow

Highlights of the Group

The Polymer Petroleum and Coal Chemistry (PPCC) group is one of among the excellent research groups working on coal and petroleum sciences in India and abroad.  The group has been engaged in the resource quality assessment and the development of indigenous processes for the rational utilization of NER low-grade coals, since its inception. The group is engaged in both applied and fundamental research in areas that are vital to the polymer and oil industries. The groups contributed significantly in the development of tailor made polymeric additives for use in the petroleum and allied industries.  Research projects of the division are focused on modification of polymers by introduction of functional groups, grafting, thermal and light stabilization of polymers, on mechanism of high conversion and living radical polymerization systems (ATRP), preparation of novel polymeric materials based on renewable natural resources. Studies on kinetics and rheology of high polymers and petroleum products are major thrust area research of the division. The group is also working on different aspects of coal and environmental issues including national emission inventories for coal-based industries.

Mandate of the Group

  • The mandate of the group is to develop indigenous processes for effective and gainful utilization of low-quality NER coals for the benefit of the people and society of India. It is mandate to assess and mitigate the environmental degradation during utilization of these coals in the region.
  • The mandate of the group not only confined to the area of development of tailor made polymers used in the petroleum and allied industries but also in the development degradable polymers, bio-lubricants, bio-composites and nano-composites.

Vision and mission of the Group:
The mission of the groups is to maintain a vibrant research profile that truly captures the needs and changes of the modern society to perform fundamental research along with applied research that cater to the broader economic, societal and environmental development and growth of the country. This is achieving through interdisciplinary research that crosses barriers across chemistry, physics, biology and materials science.

  • Development of new, cheap and environment friendly processes for beneficiation of NER high sulfur low-quality coals towards utilization in metallurgical coke industries and power plants
  • Production of high-value carbon materials from low-quality NER coals and their industrial application
  • Development of Bio-composites having environmental benefits compared to conventional composites as they offer a possibility to replace traditional components with biodegradable alternatives.
  • Optimum utilization of the natural resources in the NE region.
  • Stimulate collaborative efforts among industry, universities, government, and professional societies
  •  Advance the development and exchange of relevant state of art knowledge and technology
