Research & Development (R&D)

The R&D activities of MRPL are primarily categorized under technology cum catalyst development, value addition to refinery molecules, Artificial Intelligence/Machine learning for process optimization & reliability improvement and niche product development through in-house and/or collaborative projects with other institutions. In house research projects are related to odor abatement in off gas streams, residue up gradation, super hydrophobic coatings polymer blends/composites and data driven research to improve yield and energy efficiency. Through collaborative research, MRPL R&D has taken up various research projects with premier institutions like CSIR-NCL, CIPET, CSIR-IICT, IITG, NITK, NMAMIT etc. Out of these, few projects are in pilot scale and some are in initial stages of development.

Eighteen patents have been filed till FY 2022-23, out of which four have been granted already while others are at different stages of approval from the Indian patent office.
