Biocatalytic methanation of hydrogen and carbon dioxide in a fixed bed bioreactor.

摘要: Biocatalytic methanation of H2 and CO2 was studied in a fixed bed reactor system consisting two solid state bioreactors series connected to recirculation system. Bioreactors were packed with mixture vermiculite shales granular perlite material as support material. A maximal methane productivity 6.35l/lreactord achieved at hydrogen feed rate 25.2l/lreactord, while conversion 100%. However, stable operation the this efficiency remains be achieved. Very simple design, constructed from low cost materials, idea exploiting waste robust source nutrients for methanogens makes study very interesting regarding overall usability suitability part decentralized energy
