May 22, 2020 · Owing to the favorable electrostatic environment within a suitable confined space, TIFSIX-2-Cu-i is able to distinguish the three C5 olefins (trans-2-pentene, 1-pentene and isoprene) with a high uptake of trans-2-pentene (3.1 mmol·g-1).

Steam cracking processes produce C5 hydrocarbon streams having a very high concentration of cyclopentadiene and dicyclopentadiene, in addition to linear C5 dienes, isoolefins, and acetylenes,...

Isoprene feedstock is produced by Chevron Phillips Chemical at its plants in Cedar Bayou and Sweeny, Texas. Isoprene feedstock is a co-product of ethylene production. Isoprene feedstock is used to produce isoprene, which is used to make polyisoprene rubber for tires.

Dec 1, 2021 · Liquid adsorption separation of linear alkyne/olefin mixtures, covering 1-pentyne/1-pentene (C 5) and 1-hexyne/1-hexene (C 6), in FAU zeolites, was performed further to investigate the separation performance for alkynes and olefins.

This paper reviews recent progress of direct catalytic dehydrogenation and oxidative dehydrogenation of C5/C6 alkanes, and points out that the key is to develop C5/C6 alkanes dehydrogenation catalyst for selective preparation of corresponding mono-olefins.

Jan 25, 2022 · The C 5-olefin yields increased with an increase in the H 2 S/iso-C 5 ratio. The highest C 5 -olefin yield was obtained at the reaction temperature of 600 °C and an H 2 S/ iso -C 5 ratio of 2. The stability of Fe/SiO 2 was evaluated under these conditions for approximately 400 min, as shown in Fig. 2 (c).

MFT catalysts extend to C5 olefin selectivity improvements. The results obtained in pilot testing were further validated using operating data from multiple MPC units.

pillared hybrid porous materials (ZU-62 and TIFSIX-2-Cu-i) to wards the challenging separation of C5 olefin mixtures (trans-2-pentene, 1-pentene and isoprene). These two adsorbents not only exhibit the unprecedented separation performance, but also show excellent recycle performance.

Jun 1, 2023 · To improve the atomic utilization efficiency, different generation pathways of light olefins and methane in the catalytic pyrolysis of C 5 hydrocarbons were analyzed, and the effects of reaction conditions and zeolite types were investigated.

Nov 21, 2012 · The C 5 olefins are produced by both catalytic and steam cracking of liquid feedstocks. This chapter provides a conceptualized scheme for separation of mixed C 5 stream, which combines processes used in several refineries.
