The aromatized/alkylated gasoline components were originally transparent and clear; what is the reason why they are now green in color? What are the common reasons for gasoline to turn green?
There are also those that turn black; this usually happens when the alkylation process starts, as the interior is too dirty. Just let it settle; in the aromatization process, carbon black is usually present during feeding, and it may also be present in the product. There are two main reasons: first, some manufacturers use activated carbon for desulfurization; second, there are issues with the operation of the distillation tower
Side reactions occurred in alkenes, dienes, and alkynes, resulting in the formation of green oil.
During hydrogenation, the byproduct of alkynes is green oil; however, there are virtually no alkynes in the C4 compounds after etherification, with their content being practically negligible
【Reply to Floor 7】 Thank you, I now understand what’s going on. A certain amount of this butylene is produced as a by-product in the large ethylene plant, and green oil is present in this raw material; I mentioned that a few days ago someone brought photos and asked why the sample after washing was green
In naphtha alkylation, are there any side reactions involving olefins and alkynes?
