Syngas production from ethanol dry reforming using cu-based perovskite catalyst

This paper reports about production of syngas from dry reforming of ethanol (EDR) by using LaCuO3 and CeCuO3. The catalysts were prepared via the citrate sol-gel method and characterized by BET, TPO, H2-TPR, FTIR, HR-TEM, SEM-EDX and XPS. The EDR tests were run in a stainless-steel fixed-bed reactor...
