Abstract
Pyrolysis gasoline is stabilized by hydrotreating in the presence of a catalyst of cobalt-tungsten sulfide supported on high surface area alumina. Dienes are selectively hydrogenated and mercaptan sulfur is reduced, without production of polymer and the product has an ASTM distillation curve essentially identical to the feed.
Claims8
In a process for selectively hydrogenating dienes in a liquid feed containing dienes, the improvement comprising:
- effecting said hydrogenating in the presence of a cobalt-tungsten sulfide catalyst supported on high surface area alumina to produce a hydrotreated product without formation of dimers and higher polymers.
