  • Patent number: 10087411
    Abstract: A method for separating ethanol from fermented biomass is provided. Fermented biomass that is rich in ethanol is used directly as packing material in a distillation column, and a small amount of water at the bottom of the column is used to efficiently transfer heat to the biomass at the bottom of the column. The fermented biomass packing has a high ratio of surface area to volume, making an efficient packing material. As vapor condenses on the biomass, diffusion of ethanol/water vapor from the body of the biomass enriches the ethanol concentration at the surface of the biomass. Droplets containing lower concentrations of ethanol drip downwards from the biomass, and vapors containing higher concentrations of ethanol rise upwards from the biomass, resulting in a higher concentration of ethanol at the top of the column than was initially in the biomass.

    Abstract: A process removes metal impurities from an untreated chemical liquid, which includes a silylating agent. The process includes providing a strongly acidic cation-exchange resin in which a cation-exchange group is immobilized to a resin membrane or an integral structure of a particle-removing membrane and an ion exchange resin membrane in which a strongly acidic cation-exchange resin has been chemically introduced onto surfaces of pores in a porous resin. The wettability of the ion exchange resin membrane is thereafter improved by contacting the ion-exchange resin membrane with an organic solvent. The metal impurities are then removed from the untreated chemical liquid by passing the untreated chemical liquid through the ion-exchange resin membrane.

  • Patent number: 8158841
    Abstract: To provide a method for hydrotreating a synthetic hydrocarbon oil, which removes olefins and oxygen-containing compounds by hydrotreatment with the gasification rate restrained and can efficiently convert the synthetic hydrocarbon oil generated by the FT process to a liquid fuel suitable as a fuel for diesel-powered vehicles. A hydrotreating method is disclosed in which a synthetic hydrocarbon oil generated by FT synthesis is hydrotreated using a catalyst in which a definite catalytic metal is allowed to be carried on a support, under definite reaction conditions, with the gasification rate restrained to a definite value or less, thereby removing the olefins and the oxygen-containing compounds.

  • Publication number: 20120074042
    Abstract: Disclosed are embodiments relating to a process for reducing the total acid number of a hydrocarbon feed by contacting the feed with a metal titanate catalyst having an MTiO3 structure wherein M is a metal having a valence of 2+, resulting in a hydrocarbon product having a final total acid number lower than the initial total acid number of the feed. The process is useful for pretreating high acid crudes prior to further processing thus avoiding corrosion of equipment used in refining operations. The process can be integrated into conventional refining operations in order to treat various refinery streams. In one embodiment, a process is provided for refining a low acid crude oil and a high acid crude oil by separately introducing a relatively low acid crude oil feed and a relatively high acid crude oil feed to an atmospheric distillation column, wherein the relatively high acid crude oil feed is contacted with a metal titanate catalyst prior to introduction to the atmospheric distillation column.

  • Patent number: 8137565
    Abstract: Methods and apparatus relate to handling of organic contaminants in aqueous streams. The methods and apparatus enable removing the contaminants, such as naphthenic acids, from the aqueous streams and then converting the contaminants into hydrocarbons. The removing and converting of the organic contaminates results in treated discharge and generation of the hydrocarbons, which add to amount of hydrocarbon recovery.

  • Patent number: 8118994
    Abstract: Naphthenic acid corrosivity of hydrocarbon feedstocks is correlated with the chemical composition of naphthenic acids, and especially with a ratio between an alpha fraction and a beta fraction of naphthenic acids. Contemplated plants, configurations, and methods are directed to reducing naphthenic acid corrosivity of hydrocarbon feedstocks by increasing the beta fraction over the alpha fraction.
