Chaudhary Charan Singh Haryana Agricultural University, Hisar

Chaudhary Charan Singh Haryana Agricultural University popularly known as HAU, is one of Asia's biggest agricultural universities, located at Hisar in the Indian state of Haryana. It is named after India's seventh Prime Minister, Chaudhary Charan Singh. It is a leader in agricultural research in India and contributed significantly to Green Revolution and White Revolution in India in the 1960s and 70s. It has a very large campus and has several research centres throughout the state. It won the Indian Council of Agricultural Research's Award for the Best Institute in 1997. HAU was initially a campus of Punjab Agricultural University, Ludhiana. After the formation of Haryana in 1966, it became an autonomous institution on February 2, 1970 through a Presidential Ordinance, later ratified as Haryana and Punjab Agricultural Universities Act, 1970, passed by the Lok Sabha on March 29, 1970. A. L. Fletcher, the first Vice-Chancellor of the university, was instrumental in its initial growth.

    Characterization of biochar prepared from coconut shell at different temperatures
    (CCS HAU, Hisar, 2022-07-22) Bhawna; Dahiya, Rita
    Pyrolysis process can be the solution to problems that arises due to the improper management of biowaste. This process might be used to produce valuable carbonaceous products like biochar. The present study is focused on the preparation of biochar from coconut shell at different temperatures by pyrolysis. The obtained biochar was characterized by using analytical techniques like FTIR, XRD, BET, FE-SEM and UV-Vis spectroscopy. The properties of biochar like ash content, EC, pH, carbon content and CEC were also determined using standard methods. The FTIR spectra of the prepared biochar confirmed the presence of aromatic carbon functional group in the biochar structure. From the XRD plots, amorphous structure of the biochar is confirmed. The results indicated that as the pyrolysis temperature increased, the amorphous organic phase in the biochar structure decreased. The FE-SEM images showed the porous structure of biochar prepared at a high temperature of 700 °C. The BET analysis showed that as the pyrolysis temperature increased, surface area as well as porosity of the biochar increased.
