With gasoline demand picking up, are North American refineries tight on octane supply, and how do you manage an octane supply constraint?Apr-2021

Although I work in the opposite side of the globe, and know nothing of the first part of your question, I can maybe give some perspective on the second part.
Having worked in an Axens Prime-G+ unit for a long time, I can confidently say that some elementary stuff like maintaining the correct draw temperatures in the De-Isohexaniser column can push up your total octane in the blend by a huge 2 to 3 points.
Similarly FCC gasoline split has to be optimised to balance product sulphur and octane.
Having worked in an FCC also, I can safely say that the specialty catalyst that you feed into your Fresh Cat mix plays a huge role in providing you that extra octane push. You can optimise ZSM-5 addition to your normal US-Y zeolite to give a lighter, higher octane gasoline that will tremendously boost your gasoline pool.
These are only a few ways to boost your gasoline RON/MON without even thinking about octane or octane booster chemical addition. MTBE/octane blending is a passe in my part of the world. We still maintain at least 91 octane gasoline, and occassionally do produce batches of 100 octane gasoline as per market demand.

We can suggest a way for increasing the octane and improving other numerous gasoline production parameters (that is for significantly increasing the GRM) and contextually getting climate change mitigation and other mprovements, without a negative effect of any kind. This measure is at negligible or no capital cost.
