Now...from Kellogg Research: new hydrotreating process upgrades pyrolysis gasolines Raw pyrolysis gasoline can now be upgraded economically to salable products by using Kellogg's newlydeveloped selective hydrogenation process. Of prime importance to olefin producers, the new route which will soon be placed in commercial operation permits hydrogenation of mono- and diolefins via a two-stage catalytic tech-
nique. Processflexibilitypermits production of 1) a stable, salable gasoline or 2) an olefin-free, sulfur-free stream suitable for recovery of benzene, toluene, and xylenes. And there is no loss of aromatics during processing. Typical hydrogen consumption, based on extensive pilot plant testing, is 200 SCF/bbl for salable gasoline ! and 500 SCF/bbl for aromatic streams.
Butadiene, pentadiene, and styrene can be hydrogenated effectively in the process, and the catalyst is active, rugged, and responds well to regeneration. For further details on performance characteristics, write for our booklet "The Selective Hydrogenation of Pyrolysis Gasolines."
