MTO regenerator CO and CO2 generation issue?
Thread Content
The MTO regenerator is charring; does C first convert to CO? Or does C directly convert to CO2? In that case, it converts directly into CO2? It seems to me that sometimes C is directly converted to CO2 during the operation!
It must be producing carbon monoxide; MTO regeneration is an oxygen-deficient process.
It is necessary to consider the oxygen concentration and operating temperature, as these two determine the ratio of CO to CO2.
It can directly produce CO2, or it can produce CO; however, CO eventually turns into CO2 as well. This is because environmental protection requires that the CO content in flue gases be controlled.
Still, at high temperatures, the heat released by C+O2=CO is less than that released by C+O2=CO2. . At high temperatures, it’s CC2+C=C0... but I’m not sure which one is the main one; let’s discuss it together
Thermodynamically, it has been determined that the two reactions occur simultaneously; the product distribution is kinetically controlled and depends on the C/O ratio
