钙钛矿型四效催化剂净化柴油烟气的热力学分析

THE PRINCIPLE OF THE REMODYNAMICS OF PEROVSKITE TYPE FOUR-WAY CATALYST FOR PURIFYING DIESEL SMOKE

根据热力学原理,计算吉布斯自由能的变化量,讨论柴油烟气净化反应的可行性。钙钛矿型四效催化技术是提高CxHy、PM、CO、NOx转化率和降低反应温度的有效方法,也是改变吉布斯自由能变化量ΔG的间接条件。

According to thermodynamic principle,the variation value of Gibbs free energy-was calculated and the feasibility of diesel smoke purifying reaction was discussed. Perovskite type four way catalytic technology is a effective method to reduce the reaction temperature and increase conversion rate of CxHy,PM,CO,NOx,and also the indirect conditions of changing ΔG of Gibbs free energy.
