Pyrolysis of Amaranth Inflorescence Wastes: Bioenergy Potential, Biochar and Hydrocarbon Rich Bio-Oil Production

Many agro-industrial companies grow amaranth for the subsequent production of oil, flour, cereals, flakes, and bran. After grain is extracted, waste in form inflorescences remains, which can be used to obtain useful new products. This work investigated use pyrolysis recycle inflorescence wastes (AIW). Thermochemical conversion experiments an inert medium were carried out a laboratory setup at 550 °C heating rate 10 °C/min. It was found that AIW produced 37.1 wt.% bio-oil, 35.8 pyrogas 27.1 biochar. The oil fraction obtained bio-oil contains 41.8% hydrocarbons. Thermogravimetric analysis performed temperature range from 40 1000 rates 10, 15, 20 °C/min argon (75 mL/min). kinetic parameters determined by model-free Friedman, Ozawa-Flynn-Wall, Kissinger-Akahira-Sunose methods. average activation energy values are 208.44–216.17 kJ/mol, they calculate thermodynamic parameters. results indicate application will allow efficient into value-added
