  • Publication number: 20120253091
    Abstract: The present invention relates to a method in which a catalytic reaction is used in order to produce hydrocarbons from renewable starting material derived from biological organisms such as vegetable lipids, animal lipids, and lipids extracted from macroalgae and microalgae, and more specifically relates to a method for selectively making a hydrocarbon, which is suitable for making gasoline or diesel, by removing the oxygen contained in the starting material without consuming hydrogen. In the present invention, the production takes place by bringing the starting material into contact with hydrotalcite, which constitutes a catalyst, thereby removing oxygen via a decarboxylation or decarbonylation reaction; and the starting material is one or more such material selected from triglycerides, fatty acids, and fatty acid derivatives obtained from a renewable source of supply originating from a biological organism.

  • Publication number: 20100204043
    Abstract: The present invention relates to an adsorbent for separating carbon monoxide from a gas mixture including hydrogen gas and a method of preparing the same. The adsorbent for selectively separating monoxide includes a solid material, which is a solid support impregnated and dispersed with a cuprous salt by bringing the solid support into contact with a cuprous salt solution stabilized by dissolving a cuprous salt or a cuprous salt mixture in a solvent. The adsorbent is advantageous in that the selectivity for carbon monoxide is improved, so that the amount of carbon monoxide included in the gas mixture is decreased to infinitesimal quantities, thereby producing high-purity hydrogen products.

  • Patent number: 6634119
    Abstract: Disclosed is an adsorptive ethanol drying apparatus in which microwaves are applied during the regeneration of an absorbent conducted in a continuous adsorption process for drying ethanol, so that the absorbent regeneration can be rapidly achieved at a temperature lower than that used in a conventional heating type regeneration method and within a reduced processing time, thereby being capable of allowing an efficient use of energy while improving the productivity per adsorbent mass. A method for operating the adsorptive ethanol drying apparatus is also disclosed. At an adsorption step, a vaporized ethanol azeotropic mixture is forced to pass through adsorption towers to adsorb water contained in the vaporized ethanol azeotropic mixture to an adsorbent charged in each of the adsorption towers while condensing ethanol in a storage tank.

  • Patent number: 6315816
    Abstract: A group of solid adsorbents in the form of powder, granules or pellets having improved adsorptive capacity and selectivity for ethylene and/or propylene is disclosed. These adsorbents comprise (a) a silver compound and (b) a bentonite clay support bulk of which comprises SiO2 and Al2O3 and the rest being oxides of Fe, Ca, Mg, Na and K and having sufficiently high surface area on which the silver compound is dispersed or impregnated. The support may be pretreated by polymer solutions to impart sufficient mechanical strength as measured by attrition loss. Mechanical strength may also be improved by pre-heating the support. These adsorbents are highly stable and are capable of reversibly adsorbing substantial quantity of ethylene and/or propylene at room temperature. The rates of adsorption of ethylene and/or propylene are also very high in these adsorbents, which is believed to be due to the synergistic interaction between the components of the novel composition of the present invention.

  • Patent number: 5547492
    Abstract: A method for recovering argon and hydrogen simultaneously from a feed mixture comprising argon, hydrogen, methane, nitrogen, ammonia, and moisture by passing a two stage adsorption separation (PSA). The feed gas including 4-6% hydrogen is sent to the first stage PSA to obtain a product hydrogen during the first period of adsorption step, and to obtain an intermediate product of argon and hydrogen mixture during the next period of adsorption step. The adsorbed gases are evacuated and sent to fuel gas. The intermediate product argon and hydrogen mixture is sent to the second stage adsorption bed. The effluent of adsorption step is recovered as another product hydrogen. After the adsorption step, the second stage adsorber is undergone concurrent blowdown, pressure equalization, argon recovery, argon purge, desorption production of argon, pressure equalization, pressurization with product hydrogen. Through such cyclic operation of two-stage PSA, high purity argon and hydrogen are recovered simultaneously.
