    Abstract: The present invention provides a process for preparing a high purity Fischer-Tropsch gasoil fraction, comprising: a) providing a Fischer-Tropsch-derived gasoil feedstock comprising one or more contaminants; b) providing the Fischer-Tropsch-derived gasoil feedstock to a fractionation zone and fractionating the Fischer-Tropsch-derived gasoil feedstock into two or more Fischer-Tropsch gasoil fractions having a different boiling point range, wherein at least one Fischer-Tropsch gasoil fraction is a contaminant-enriched Fischer-Tropsch gasoil fraction, which is enriched in one or more contaminants with respect to the feedstock; c) providing the contaminant-enriched Fischer-Tropsch gasoil fraction to an absorption zone comprising at least one absorbent material and contacting the contaminant-enriched Fischer-Tropsch gasoil fraction with the absorbent material to absorb at least part of contaminant; and d) retrieving from the absorption zone a purified Fischer-Tropsch gasoil fraction, which is contaminant-depleted. The invention further provides for further processes for preparing a high purity Fischer-Tropsch gasoil fraction and the use of the purified Fischer-Tropsch gasoil fraction.

    Abstract: A process for removing non-volatile, particulate mercury from crudes and condensates is disclosed. Particulate mercury in crudes can be removed by a process of first adding a halogen, such as I2. The halogen converts at least 10% of the particulate mercury into an oil-soluble mercury compound that cannot be removed by filtration or centrifugation. This oil-soluble mercury compound can then be removed by adsorption onto a solid adsorbent. The process can operate at near ambient conditions. The adsorption step can be carried out by mixing a particulate adsorbent in the halogen-treated crude and then removing it by centrifugation, desalting, filtration, hydrocyclone or by settling.

    Abstract: A crude oil feedstream is treated to remove or reduce the content of known undesired heteroatomic and polynuclear aromatic compounds containing nitrogen and sulfur by contacting the feedstream with one or more solid adsorbent materials selected from attapulgus clay, alumina, silica gel and activated carbon in a mixing vessel for a time that is sufficient to optimize the adsorption of the undesired compounds from the crude oil, subjecting the mixture to atmospheric flash distillation and then to vacuum flash distillation to recover presorbed boiling ranges of products having a lowered content of the undesired compounds, and preferably regenerating at least a portion of the solid adsorbent material for reuse in the process.

    Abstract: Processes and apparatuses for washing a spent ion exchange bed and for treating biomass-derived pyrolysis oil are provided herein. An exemplary process for washing a spent ion exchange bed employed in purification of biomass-derived pyrolysis oil includes the step of providing a ion-depleted pyrolysis oil stream having an original oxygen content. The ion-depleted pyrolysis oil stream is partially hydrotreated to reduce the oxygen content thereof, thereby producing a partially hydrotreated pyrolysis oil stream having a residual oxygen content that is less than the original oxygen content. At least a portion of the partially hydrotreated pyrolysis oil stream is passed through the spent ion exchange bed. Water is passed through the spent ion exchange bed after passing at least the portion of the partially hydrotreated pyrolysis oil stream therethrough.
