Effect of steam gasification parameters on hydrogen extraction from indirect land use change crops

ABSTRACT

Biomass green energy is becoming indispensable in worldwide applications and meets their energy demand. The extraction of hydrogen from bio-mass via coal gasification technique found higher carbon monoxide content and low hydrogen yield. This study aims to increase the production of green hydrogen energy from indirect land use change (ILUC) crops such as Cynara cardunculus L, Helianthus annuus L, Miscanthus × giganteus, and Linum usitatissimum Lvia steam gasification process with varied gasification temperature (500°C, 550°C, 600°C, 650°C, 700°C, and 750°C), and steam/biomass ratio (0.2, 0.4, 0.6, 0.8, 1.0, and 1.2) under Alkaline and Dolomite catalysts. The effect of gasification process parameters on gas concentration, gasification efficiency (CCE), and higher heating value (HHV) was studied, and it found that Miscanthus × giganteus crop yield 57.8 mol% of hydrogen, 80%, and 14.8 MJ/m³at 750°C. It was revealed from experimental results influenced by varying steam/biomass ratio on the gas concentration that hydrogen significantly increased with an increased ratio of steam/biomass and noted a higher hydrogen yield of 59% at the ratio of steam/biomass was 1.2. Similarly, the gasification efficiency (CCE) and higher heating value (HHV) increased by 79.8% and 14.9 MJ/m³, respectively. Based on this, the Miscanthus × giganteus crops subjected to catalysts process and alkaline found have maximum conversion efficiency (82%) and HHV (16.5MJ/m³) compared with those with dolomite catalysts.
