|Synthetic natural gas made from biomass (Bio-SNG) is a promising alternative to common natural gas from fossil sources. Due to its production and usage, a significant reduction of greenhouse gas emissions is expected. The competitiveness and efficiency of the methanation, the central chemical reaction of the Bio-SNG production process, has to be increased. Therefore, temperature and pressure of the methanation has been limited to a maximum of 300 °C and 5 bar. Overall, high methane yields have been reached through various optimization measures.
