Thermodynamic modelling and energy balance of direct methanation of glycerol for Bio-SNG production

The Bio-SNG produced had an LHV of 16.7 MJ kg−1 and had properties like landfill gas and biogas. An energy balance of the process determined that the electricity demand was negligible due to the low energy use of pumps and fans without the need for compressors. Operating at 8 atm, the production of Bio-SNG in the GLT-SR plant has the potential to offset 30% of the natural gas embodied energy requirement or 8.9% of the total embodied energy requirement for soybean biodiesel production from farm to use.
