Abstract:
In this work, a polygeneration process for the generation of H2, H2CH4 (a gas mixture composed of H2 and CH4, sometimes referred to as hythane), and district heat was simulated using the process simulation software IPSEpro. The process employed sorption enhanced reforming of wood chips using the dual fluidized bed steam gasification technology. In addition, two pressure swing adsorption units using carbon molecular sieve and activated carbon as adsorbents were employed in order to separate H2 and H2CH4 from the generated product gas. The simulation parameters were based on results from experimental approaches from different pilot gasifiers and a lab-scale pressure swing adsorption unit. The obtained mass and energy balances show the feasibility of the process layout for generation of H2, H2CH4, and district heat. The generated H2CH4 gas mixture could be used as supplement of fossil CH4 in natural gas grids. An overall wet fuel based production efficiency of 82 % was reached.
