title: An experimental approach aiming the production of a gas mixture composed of hydrogen and methane from biomass as natural gas substitute in industrial applications.
abstract: This work presents an experimental approach aiming the production of a gas mixture composed of H2and CH4, which should serve as natural gas substitute in industrial applications. Therefore, a lab-scale process chain employing a water gas shift unit, scrubbing units, and a pressure swing adsorption unit was operated with tar-rich product gas extracted from a commercial dual fluidized bed biomass steam gasification plant. A gas mixture with a volumetric fraction of about 80% H2and 19% CH4and with minor fractions of CO and CO2was produced by employing carbon molecular sieve as adsorbent. Moreover, the produced gas mixture had a lower heating value of about 15.5MJ·m-3and a lower Wobbe index of about 43.4MJ·m-3, which is similar to the typical Wobbe index of natural gas.
