Abstract: The invention relates to a process for the recovery of aliphatic hydrocarbons from a liquid stream comprising aliphatic hydrocarbons, heteroatom containing organic compounds and optionally aromatic hydrocarbons, involving a) liquid-liquid extraction of said liquid stream with an extraction solvent, wherein before and/or after step a) heteroatom containing organic compounds, optional aromatic hydrocarbons and optional other contaminants are removed from said liquid stream and/or from a raffinate stream resulting from step a), respectively, by contacting the latter stream(s) with a sorption agent. Further, the invention relates to a process for the recovery of aliphatic hydrocarbons from plastics comprising the above-mentioned process; and to a process for steam cracking a hydrocarbon feed comprising aliphatic hydrocarbons as recovered in one of the above-mentioned processes.

Abstract: A process for the production of furfural from a biphasic composition including furfural, an organic solvent and soluble organic debris. The said process includes subjecting the biphasic composition to a liquid-liquid separation step to provide an organic phase and an aqueous phase. The organic phase includes the organic solvent, a first portion of the furfural and a first portion of soluble organic debris. The aqueous phase includes a remainder portion of the furfural and a remainder portion of soluble organic debris. The organic phase is subjected to a distillation step to provide a furfural stream and an organic solvent stream including the organic solvent and the first portion of the soluble organic debris. The organic solvent stream is conveyed to an adsorption unit to adsorb a second portion of the soluble organic debris, forming an organic debris-depleted recycle stream.
