| description | The present study aims to analyze the performance characteristics of the biogas dry reforming process conducted in a membrane reactor using Ni/Cr catalysts and to compare these characteristics with those obtained using pure Ni catalysts. The effect of the pre-set reaction temperature, the molar ratio of CH<sub>4</sub>:CO<sub>2</sub> and the pressure difference between the reaction chamber and the sweep chamber on the characteristics of biogas dry reforming is analyzed. In the present work, the molar ratio of the supplied CH<sub>4</sub>:CO<sub>2</sub> is varied to 1.5:1, 1:1 and 1:1.5. In this case, CH<sub>4</sub>:CO<sub>2</sub> = 1.5:1 simulates a biogas. The pressure difference between the reaction chamber and the sweep chamber is varied to 0 MPa, 0.010 MPa and 0.020 MPa. The reaction temperature is changed to 400 °C, 500 °C and 600 °C. It is revealed that the highest concentration of H<sub>2</sub> is achieved using a Ni/Cr catalyst when the molar ratio of CH<sub>4</sub>:CO<sub>2</sub> is 1.5:1 at the differential pressure of 0.010 MPa and the reaction temperature of 600 °C. Under this condition, the H<sub>2</sub> yield, H<sub>2</sub> selectivity and thermal efficiency are 12.8%, 17.5% and 174%, respectively. The concentration of the H<sub>2</sub> produced using a Ni/Cr catalyst is larger than that produced using a Ni catalyst regardless of the pre-set reaction temperature, the molar ratio of CH<sub>4</sub>:CO<sub>2</sub> and the differential pressure. |
