Abstract :

Hydrogen (H2) enrichment of biogas through catalytic reforming is an attractive technique to produce energy efficient gaseous product. Since biogas has a lower heating value as compared to natural gas, therefore, H2 enrichment will enhance its energy content. Biogas dry reforming was studied over magnesium oxide (MgO) decorated nickel (Ni) catalyst supported on aluminium oxide (Al2O3). The catalyst was prepared by wet impregnation technique and characterized by XRD, H2-TPR, BET, and FESEM. The reforming tests were carried out in a fixed bed downflow reactor, within a temperature range of 650-850°C at 1bar. The synthesized catalyst performance was compared with pure Ni nanopowder at a weight hour space velocity (WHSV) of 20,000 NmLg-1h-1. The increased reaction temperature showed a positive effect on reactant (CH4 and CO2) conversions and product (H2 and CO) yields for both tested catalysts. At 850°C, the maximum CH4 and CO2 conversions of 60.0 and 82.1%, respectively, were obtained on a pure Ni catalyst with 25.5% of H2 enrichment. Whereas, with Ni0.1/(Mg0.1-Al0.9) catalyst, 38.0% of H2 enrichment was identified with 79.7 and 96.2% of CH4 and CO2 conversion, respectively. Thus, 10 wt% Mg promoted catalyst showed improved catalyst performance when compared to pure Ni with maximizing H2 proportion in biogas.
