    Dr Gunjan Kumar Agrahari

    Assistant Professor
    Chemical Engineering

    Dr Gunjan Kumar Agrahari completed his Ph D in the year 2013 from IIT Kanpur. Thereafter he worked as Post-doctoral Fellow at the Katholieke University, Leuven, Belgium. His research area during Ph D and Post-doc was Enhanced Chemical Separation Processes Employing Membranes. After joining RGIPT, he has initiated research in the area of Pyrolysis and Gasification of Biomass. Currently, he has been engaged in developing a gasification process to convert lignocellulosic agricultural residue to synthesis gas. His immediate goals include pyrolysis of methane to produce hydrogen and employing plasma gasification to treat large volumes of agricultural waste.

    He has also completed a SERB-funded research project under the CRG scheme of ? 40 Lakh. The objective of the project was the extraction and recycling of rare earth metals from consumer waste. After the completion of the project, the developed facilities are being used for heavy metal extraction and recycling from various industrial waste using novel devices such as hollow fiber membrane contactors and coiled flow inverters.

     He has also initiated several small projects for undergraduate students. Currently, the ongoing projects include the conversion of agri-waste to biochar for water purification, the forward osmosis process for treating petrochemical industry wastewater, and the development of a catalyst for the conversion of synthesis gas to methanol.
