Effect of Gasification Temperature on Biohydrogen Derived from Waste Agro Products for Alternative Fuel Application

<div class="section abstract"><div class="htmlview paragraph">Hydrogen fuel is becoming a popular choice in many energy applications because of its innovative green technology, which produces zero carbon emissions. It also offers better efficiency than fossil fuels. Current research focuses on obtaining hydrogen energy from agricultural waste using a gasification process. This process involves heating the waste at gasification temperatures 300, 400, 500, 600, and 700°C, maintaining a residence time of 60 minutes, and applying a gasification pressure of 20 bar. The effects of gasification temperature on the effectiveness of hydrogen production are examined. At a high gasification temperature of 700°C and a residence time of 60 minutes, the processed agro feedstock showed impressive results. It achieved a molar fraction of 12% carbon dioxide (CO<sub>2</sub>), 31% methane (CH<sub>4</sub>), and 55% hydrogen (H<sub>2</sub>), leading to an improved hydrogen yield of 15.2 mol/kg. Additionally, it demonstrated better hydrogen selectivity at 8.1 and a higher gasification efficiency of 61%, outperforming results from other gasification temperatures. Bio-green hydrogen is used as an alternative fuel for energy purposes.</div></div>
