Experimental assessment reveals enhanced methane yield using a bimetallic catalyst in biogas-derived CO2, suggesting effective renewable gas production.
In a fluidized bed reactor, the Sabatier reaction was carried out, using a bimetallic Ni/Fe catalyst supported by g-Al2O3 and zeolite 13X as water adsorbent. The objective is to study the methane yield of a mixture made up of CO2 (such as that present in a biogas) and renewable hydrogen; that is, the production of Synthetic Natural Gas (SNG) or Renewable Gas (RNG). This product is also known as Biomethane.
