Waste Coconut oil meal to Hydrogen production through combined steam/water gasification with varying operating parameters and NaCl additions

The coconut tree, which gives millions of people access to food, shelter, and employment possibilities, is a symbol of prosperity in tropical places. Coconut meal, a byproduct of the oil and coconut milk industries, was gathered and processed to produce biofuels. In this study, sustainable hydrogen production from Coconut oil meal (COM) using a combination of steam and water gasification is experimented. To boost the production of hydrogen early in the gasification process, the tar generated was mixed with COM feedstock. This study investigated the impacts of varying a number of operational parameters, such as the concentration of the additive (NaCl at 5, 10, and 20%), the reaction duration (25, 50, and 75 minutes), and the gasification temperature (450, 500, and 550 °C). the experimental results revealed that higher gas yields (8.9 mol/kg) and higher H₂ selectivity (9.5 mol/kg) were obtained with increases in gasification temperature (550 °C) and reaction time (75 minutes), respectively, of 34.6% and 37.5%. Additionally, when the optimized concentration of 10% of NaCl additions the gas output is raised by roughly 9.9 mol/kg and the H₂ selectivity is increased by approximately 41.3%. Consequently, at higher operating settings, gas output and hydrogen generation by COM gasification are improved.
