  • Publication number: 20220241749
    Abstract: The invention relates to a process for the liquid-phase separation of xylose from a mixture of C5 and C6 sugars comprising at least xylose and glucose, by adsorption of xylose on a zeolitic adsorbent based on FAU-type zeolite crystals having an Si/Al atomic ratio of less than or equal to 1.5 comprising barium, wherein: said mixture is brought into contact with said adsorbent, by liquid chromatography, to obtain a glucose-enriched liquid phase and a xylose-enriched adsorbed phase; on the one hand, said glucose-enriched liquid phase is recovered and said phase adsorbed on said adsorbent is desorbed by means of a desorption solvent in order to recover the xylose on the other hand.

  • Patent number: 10961172
    Abstract: A process for purifying an olefinic feedstock containing olefins with 4 carbon atoms and impurities including isobutanal, ethanol and acetone, the process including a pre-treatment containing at least one step of eliminating the ethanol and the water present in the olefinic feedstock and a step of simultaneously eliminating the isobutanal and the acetone, by passing the feedstock from the pre-treatment over at least one fixed bed of at least one adsorbent containing at least one material with a zeolite framework, the material with a zeolite framework being chosen from zeolites, AIPOs, SAPOs and mixtures thereof; the step of simultaneously eliminating the isobutanal and the acetone being carried out at a temperature of between 0 and 200° C., at a pressure of 0.1 to 10 MPa and with an hourly space velocity of the feedstock over the fixed bed of 0.1 to 10 h?1.

  • Patent number: 10428282
    Abstract: This invention pertains to a method for purifying an olefinic feedstock that comprises olefins with 4 carbon atoms and impurities including isobutanal, ethanol, and acetone, where said method comprises a pretreatment that comprises a step for eliminating acetone and optionally a step for eliminating the water that is present in said olefinic feedstock, and a step for simultaneously eliminating isobutanal and ethanol by running the feedstock obtained from the pretreatment over at least one fixed bed having at least one adsorbent that comprises at least one porous refractory oxide-based material, optionally impregnated with one or more alkaline or alkaline-earth cations; where said step for simultaneously eliminating isobutanal and ethanol operates at a temperature of between 0 and 200° C., at a pressure of 0.1 to 10 MPa, and with an hourly volumetric flow rate (VVH) of the feedstock on the fixed bed of between 0.1 and 10 h?1.
