Experimental investigation of exothermic heat during CO2 methanation and its heat transfer coefficient measurement in a bubbling fluidized bed reactor |
초록 |
As one of clean fuel technologies, CO2 methanation is recently paid attention as it captures and converts CO2 into CH4 by reacting with H2 gas. An exothermic heat during CO2 methanation is an important issue to be solved to achieve the maximum CH4 production and its operating efficiency. To achieve a stable reaction temperature throughout the fluidized bed reaction chamber, the investigation of exothermic heat generation and heat transfer coefficients was performed during CO2 methanation. First, the increase in the reactor temperature due to the exothermic heat of CO2 methanation was understood by varying the conditions of the amount of reactant gas and the ratio of inert material (or height) at a constant temperature, Umf, and pressure conditions. Then the heat transfer coefficients in a fluidized bed reactor were investigated at the temperature (250 – 450 oC), minimum fluidizing velocity (1.3 – 4.0 Umf), and reaction pressure (1 – 5 bar) using nickel based bed material. The current study is expected to be an important material for the development of a fluidized bed reactor that handles the exothermic CO2 methanation reaction. |
