제목 A study on CO2 methanation properties of Ni-based catalyst in a bubble fluidized bed reactor
초록 The energy storage systems (ESS) for storing unused power and stabilizing power supply are required to prepare for increase in the share of renewable energy. A power to gas, methanation is most suitable for long-term, and large-capacity storage. The methanation is a method of converting carbon dioxide (CO2) into methane (CH4) and storing it as energy, which can contribute to greenhouse gas reduction. We investigated the CO2 methanation performance of Ni/Al2O3 catalyst at the various conditions in the bubble fluidized bed. The axial gases concentration, temperature, and conversion were densely analyzed. Thetemperature increases by up to 11 oC from 340 to 351 oC within the first 30mm of the bed. The CO2 conversion was about 90% within 50mm from the bottom of the reactor and was maintained above the height. The Ni/Al2O3 catalyst had a highest CO2 conversion of 94% at 320 oC. In addition, a reaction kinetic model using modified factors was proposed and compared to experimental data.
