The global trade and use of C4 Raffinate, an essential hydrocarbon stream in the petrochemical industry, is included in the C4 Raffinate market. C4 raffinate, also referred to as Raffinate-1 or Raffinate-2, is the residual C4 fraction that remains after 1,3-butadiene and isobutene are extracted from mixed C4 streams. It is derived from naphtha cracking. It is a vital feedstock for the production of methyl tert-butyl ether (MTBE), polybutenes, alkylate gasoline, and ethylene-propylene copolymers, which support industries including fuels, plastics, and synthetic rubber. Its main components are n-butane, isobutane, and butene isomers.
