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.
