  • Patent number: 8334418
    Abstract: The invention relates to using gas hydrate (clathrate and semi-clathrate) together with a catalytic formulation, including catalyst and anti-foaming agent, to separate specific gases from a gas mixture. In particular, compound hydrate is formed from a mixed gas feedstock to concentrate one or more desired gas species in the hydrate phase and the remainder in the gas phase. The hydrate is then separated from the gas phase and dissociated to produce a gas stream concentrated in the desired species. Additives that both accelerate the growth of hydrate and facilitate dissociation and separation are added to improve the rate of reaction and, at the same time, eliminate hard-to-break foam produced by the catalyst, thereby enhancing the total throughput of the complete process. The addition of some materials can also result in changes in the density of the hydrate product, which can be useful for optimizing the separation of hydrate from unreacted liquid and/or rejected gas.

  • Publication number: 20110230572
    Abstract: Improved reaction efficiencies are achieved by the incorporation of enhanced hydrothermally stable catalyst supports in various water-forming hydrogenation reactions or reactions having water-containing feeds. Examples of water-forming hydrogenation reactions that may incorporate the enhanced hydrothermally stable catalyst supports include alcohol synthesis reactions, dehydration reactions, hydrodeoxygenation reactions, methanation reactions, catalytic combustion reaction, hydrocondensation reactions, and sulfur dioxide hydrogenation reactions. Advantages of the methods disclosed herein include an improved resistance of the catalyst support to water poisoning and a consequent lower rate of catalyst attrition and deactivation due to hydrothermal instability. Accordingly, higher efficiencies and yields may be achieved by extension of the enhanced catalyst supports to one or more of the aforementioned reactions.

  • Patent number: 8003843
    Abstract: The present invention relates to a new method for a safe transport of ethyne in form of ?-alkynols as precursors for ethyne. The new method comprises three steps. In a first step the synthesis of the ?-alkynol(s) is performed by reacting ethyne with (a) carbonyl compound(s). The second step comprises the transport of the resulting ?-alkynol(s) in a safe manner, whereas the safety requirements for this transport are not as high as for ethyne because ?-alkynol(s) are normally classified for transportation as hazardous class 3. In the third step the ?-alkynol(s) can be cleaved and the ethyne and the carbonyl compound(s) can be obtained in the cleavage reaction and can be separated to yield pure products for further applications.
