Abstract

The effect of SO₂ on the oxidative conversion of hydrogen and methane in a wide range of temperatures of 400–1500°C at a pressure of the reacting mixture of 1 atm was studied by numerical kinetic analysis. The analysis showed that sulfur dioxide could have both accelerating and retarding effects on the oxidative conversion of hydrogen and methane, which is due to the participation of SO₂ and the products of its chemical transformation in the conjugated process. An accelerating effect of SO₂ on the oxidative conversion of hydrogen and methane was observed at low temperatures, and a retarding effect at elevated temperatures.

在宽温度范围内二氧化硫对甲烷和氢气氧化转化率影响的动力学分析

摘要

通过数值动力学分析研究了SO ₂对400-1500°C的宽温度范围内，1atm的反应混合物压力下氢和甲烷的氧化转化的影响。分析表明，二氧化硫对氢和甲烷的氧化转化既有促进作用，也有抑制作用，这是由于SO ₂参与共轭过程及其化学转化产物所致。在低温下观察到SO ₂对氢和甲烷的氧化转化的加速作用，而在升高的温度下观察到阻滞作用。
