摘要：利用不同的状态方程分别计算了甲醇催化裂解重整制氢系统中各个纯组分的压缩因子,通过与文献值的比较可知PR方程适合该系统压缩因子计算。运用PR状态方程,计算了常压和加压下甲醇催化裂解重整制氢系统的平衡常数及平衡组成,考察了不同的反应温度、压力及原料液配比对平衡组成的影响。结果表明,升高温度、降低压力、适当提高原料液中的甲醇含量,均有利于平衡常数的提高,其中温度的影响较为显著。
Using different equations of state to calculate the compressibility factor of pure component in the reaction system of hydrogen production by catalytic decomposition and steam reforming of methanol, it can be obtained by comparing the literature data and calculated data that the equation of state of PR was suitable to calculate the compressibility factor of this reaction system. Using the equation of state of PR, the equilibrium constants and compositions were calculated at atmosphere and under pressure in this reaction system. The effect of reaction temperature, pressure and the mass ratio of methanol to water on the equilibrium composition were also studied. It shows that raising temperature, reducing pressure and increasing the ratio of methanol in the input material can increase the equilibrium constants of the reaction system, among which the effect of temperature is marked.
