Thermodynamic analysis of CO2-H2O reforming for methanol production
摘要
Abstract
CO2-H2O reforming for methanol production is a promising way for effective use of CO2 , which is challenging from both economic and environmental view points. It is of significance to make a thermodynamic analysis for CO2-H20 reforming system, so as to find out the reasonable reaction conditions and improve the selectivity and yield of methanol. Based on the principle of minimum Gibbs free energy, thermodynamic equilibrium calculation was carried out to CO2-H2O reforming system. The influence of the factors (temperature, pressure and raw material ratio, etc) on the equilibrium composition of the reaction system was analyzed. The results show that the temperature has little impact on the equilibrium composition; the equilibrium composition of the system increases with the increase of pressure and H2O/CO2 molar ratio. The appropriate reaction conditions are H2O/CO2 molar ratio of 7 : 3 , the system temperature about 500 K and the pressure 8 MPa. This study provides a powerful theoretical support to optimize reaction conditions of CO2-H2O reforming.关键词
