Can excessive carbon monoxide in the new hydrogen lead to a loss in gasoline octane rating?
No, CO is converted into methane and water after hydrogenation, but this affects the reaction process, mainly due to changes in temperature.
It probably won’t, but high levels of carbon monoxide can affect the catalyst.
What was said upstairs is correct; excessive carbon monoxide in green hydrogen can cause catalyst poisoning, mainly due to the formation of nickel carbonyl
Excessive levels of carbon monoxide have an impact on desulfurization, reducing the desulfurization efficiency; this leads to an increase in temperature, causing unnecessary saturation of olefins, and it can also result in a loss of octane rating.
Methanation reactions occur, releasing heat; CO poisons the catalyst. Throughout this process of high heat generation, gasoline desulfurization reactions take place, and olefins are also consumed in large quantities, so the octane rating decreases – though not as a direct result of this
Is this a friend from Dongying? Same problem. The same lesion.
The presence of carbon monoxide has an inhibitory effect on gasoline hydrodesulfurization; to achieve the same degree of desulfurization, it is necessary to increase the temperature. A higher temperature leads to greater hydrodesulfurization, which in turn increases the olefin saturation rate and thus reduces the octane rating.
When carbon monoxide reacts with hydrogen to produce methane and water, overheating can occur easily. Additionally, nickel hydroxide is likely to form, causing the catalyst to become inactive
