Biomass Gasification: Synthetic Natural Gas

This lecture covers the thermochemical conversion of biomass into synthetic natural gas through gasification and methanation processes. It explains the principles of conventional thermochemical routes, the stoichiometry of methane synthesis from wood, and the block flow superstructure for gasification and methanation. The lecture also discusses flowsheet generation, energy integration models, process performance indicators, and the environmental impact of the process. Various scenarios for synthetic natural gas production are analyzed, considering efficiency, investment costs, and biomass logistics. The lecture concludes with the production of synthetic natural gas from wood, highlighting the benefits of co-production of biofuels and the potential for negative emissions through CO2 capture.
