  • SELECTIVE HYDROGENATION OF UNSATURATED ALIPHATIC HYDROCARBONS IN PREDOMINANTLY AROMATIC STREAMS
    Publication number: 20090326291
    Abstract: The selective saturation of unsaturated aliphatic hydrocarbons (e.g., diolefins) in a hydrogenation feed stream comprising an aromatic compound (e.g., benzene) and one or more nitrogen compounds renders is beneficial when the stream or a portion thereof is subsequently treated (e.g., with a zeolitic adsorbent) to remove nitrogen. In particular, the selective saturation of, for example, olefins and diolefins prolongs the life of the nitrogen guard bed. In a representative embodiment, the selective hydrogenation is applied to a recycle benzene-containing stream recovered in the separation section (e.g., from the benzene/toluene splitter overhead) of a styrene production process, prior to treatment with a nitrogen guard bed adsorbent.

  • Process for para-xylene production from 2,4,4-trimethylpentene
    Publication number: 20080312482
    Abstract: The subject process obtains a high yield of high-purity para-xylene from 2,4,4-trimethylpentene as contained in butene dimer.

Aromatization is effected using a catalyst comprising a large-pore molecular sieve. Each of the processing steps may be tailored to the overall objective of high para-xylene yield from a relatively inexpensive feedstock.
