C9+ Cut is a complex combination of Hydrocarbons produced by the Distillation of the Pygas from a Steam Cracking process thereafter treated with Hydrogen in the presence of a Catalyst. It consists predominantly of Aromatic Hydrocarbons having Carbon numbers in the range of C9 through C10 and boiling in the range of approximately 140 °C to 200 ...

Hydrotreating is the key technology for C9 cut upgrading. Centering on the hydrotreating utilization of C9 cuts, several new processes were summarized, including production of premium boiling aromatic solvent or gasoline blend, flash oil hydrogenation to solvent and conversion of hydrogenated C9 cuts by hydrodealkylation and transalkylation to ...

C5 aliphatic and C9 aromatic resins can be modified by mixing the two feed streams together at a carefully chosen ratio to produce hybrid polymers. This ratio determines the aliphatic/aromatic balance of the resin, which is an essential determinant of the resin’s compatibility.

Pyrolosis gasoline or pygas (C5+ cut) is a liquid by-product derived from steam cracking of various hydrocarbon feedstocks in olefin plants. A typical Process Flow Diagram (or PFD) explains the process for pygas processing or pygas hydrotreating.

2018年6月19日 · Increase the value of steam-cracker pyrolysis gasoline (pygas) using conversion, distillation and selective hydrogenation processes. Pygas, the C5–C9 fraction issuing from steam crackers, is a potential source of products such as dicyclopentadiene (DCPD), isoprene, cyclopentane, benzene, toluene and xylenes (BTX).

C5+ is a complex mixture of C5 hydrocarbons rich in cyclopentadiene, piperylene, and isoprene. This material is a colorless liquid with a strong gasoline-like odor. It is highly volatile (evaporates quickly) and does not readily mix with water (slightly soluble). C5+ is produced during the manufacture of benzene from pyrolysis gasoline (pygas).

The C9-C10 fractions are precisely cut to obtain a plurality of excellent raw materials of petroleum resin.

The C 9 + Raffinate, or C 9 + Cut, is the heavier Bottom Fraction from the fractionation process. Source: EnggCyclopedia, Typical Process Flow Diagram (PFD) – Pygas Processing . Identifiers
