Can straight-run gasoline be used as a feedstock for the hydrogenation of gasoline and diesel?
Thread Content
Straight-run gasoline contains a high amount of saturated hydrocarbons, resulting in a low octane rating! Can straight-run gasoline be used as a feedstock for diesel and gasoline hydrogenation? Please explain the reason! It would be better to be more specific, thank you!
May I ask, the original poster, do you know that straight-run gasoline contains a high amount of saturated hydrocarbons and no olefins? Yet you still ask whether it can be hydrogenated? As raw materials for gasoline and diesel, this is even less feasible; gasoline hydrogenation refers to the catalytic hydrogenation of gasoline, while diesel hydrogenation refers to the hydrogenation of diesel produced by catalytic coking and other processes. Straight-run gasoline can no longer be used as a base gasoline for blending gasoline; it can only be used as a chemical raw material or a feedstock for reforming. It also cannot be used directly as a product after hydrogenation. However, prior to entering the reformation process, hydrogenation pretreatment is carried out first to remove some toxic substances.

The original poster actually proposed a direction for gasoline refining processes that were not carried out in the past but might be implemented in the future. In the past, due to lax control over sulfur content in gasoline, straight-run gasoline could generally be used directly as a component in gasoline blending. However, with the implementation of the National V gasoline standard, which imposes strict controls on sulfur content, it is entirely possible to carry out hydrodesulfurization on straight-run gasoline, rather than using a process to saturate the unsaturated hydrocarbons in the oil. Additionally, gasoline hydrogenation is also a method for refining straight-run gasoline to obtain light solvent oils; of course, naphtha hydrogenation as a feedstock for reforming is just one of them. Both straight-run gasoline and straight-run diesel can be used as feedstocks for hydrogenation in hydrogenation units; the purpose of hydrogenation is to remove impurity elements such as sulfur and nitrogen, rather than to saturate unsaturated hydrocarbons. After hydrogenation, there is a slight loss in the oil product, meaning that the proportion of lighter fractions increases.
