Factors Affecting Gasoline Hydrogenation
Thread Content
What impact will unqualified MTBE introduced into the gasoline hydrogenation unit have on the gasoline hydrogenation process?
How could substandard MTBE end up in gasoline hydrogenation? Isn’t the feedstock for gasoline hydrogenation catalytic gasoline?
In other words, if substandard MTBE is dumped into the waste oil tank, it occupies the catalytic gasoline pipeline; a small amount of MTBE remaining in that pipeline is carried into the plant when feeding material for gasoline hydrogenation. It hasn’t been done this way yet.
Similarly, our device encountered the same problem. What reaction occurs when MTBE is added? What impact does it have on the product?
First, it is necessary to determine what aspects of the MTBE product quality are inadequate – whether it contains wax (after alkali treatment), and whether the total sulfur content is below 10. If so, and if the amount introduced is not large, the impact will be minimal; at most, it may have a certain effect on the temperature rise in the reactor； 2. If the amount introduced is high, it will disrupt the temperature rise in the entire reaction system, leading to problems with sulfidation. 3. An excessive amount of wax can have an adverse effect on the catalyst. It’s just my personal opinion; I’d appreciate it if an expert could answer. I only have a basic understanding of gasoline hydrogenation, and I just want to learn more about it :)
MTBE is an ether; when it comes to gasoline hydrogenation, it’s hard to say for sure – it can remove sulfur, but it can certainly also remove oxygen. The removal of oxygen results in the formation of olefins, and if gasoline hydrogenation does not eliminate these unsaturated olefins, it will increase the olefin content in the gasoline.
