| Popis: | Non-catalytic gasification of canola meal for the production of syngas was studied in lab-scale fixed bed gasifier and pilot-scale fluidized bed gasifier. Various experiments were undertaken in order to study the effects of different gasification parameters on gas composition, H2/CO ratio, gas yield, syngas yield, lower heating value (LHV), and carbon efficiency (CE). Fixed-bed experiments were performed to study the effects of operating temperature in the range of 650–850 °C and equivalence ratio in the range of 0.2–0.4. Steam, carbon dioxide (CO2), and oxygen (O2) were used as gasifying agents. The experimental results show that steam gasification delivers a gaseous product with a high H2/CO ratio (2.7) and LHV (193.0 MJ/m3). Oxygen gasification attributed to maximum CE (65.5 %). CO2 gasification contributes to high gas yield (82.8 mol/kg biomass). During fluidized bed gasification study, it was found that using steam as gasifying agent leads to more H2 production as compared to that for O2 and CO2 gasifying agents. Thus, it leads to high H2/CO ratio, syngas yield, and LHV of product gas. Regarding CE for O2 gasification and gas yield for CO2, observations were similar to those for fixed bed system. |
