Simulation of Biomass-to-SNG Process via Pressurized Interconnected Fluidized Beds

Abstract:

Biomass-to-SNG technology is one of the most important applications of biomass energy. The simulating model of the SNG production via interconnected fluidized beds was established and the biomass-to-SNG process was simulated. The effects of the operating conditions of the gasifier, like the gasification pressure, gasification temperature and the steam to biomass ratio (S/B), on the composition of crude methane gas were studied. The simulating results showed that there was an optimum gasification temperature and pressure for the highest methane content in the crude methane gas, while S/B had adverse effects on it. To achieve higher methane content, the suitable gasification temperature is about 750 °C, S/B is about 0.4, and the gasification pressure may be not too high.
