  • Publication number: 20190210870
    Abstract: Method for stable ethanol steam reforming, wherein a catalytic ethanol reforming is carried out in two vessels operating in parallel mode both filled in with a catalyst active for this reaction, with the first vessel acting in operation mode, generating an hydrogen rich stream, and the parallel vessel, acting in regeneration mode, made flowing with steam in order to carry out the gasification of carbonaceous compounds deposited on the catalyst.

  • Publication number: 20190039038
    Abstract: An apparatus for carrying out endothermic reactions including a plurality of catalytic vessels, immersed in a combustion chamber having a contiguous overlaid convection chamber enclosing a top portion of the catalytic vessels wherein heat is recovered at a lower temperature level from the flue gases from the combustion chamber. The catalytic vessels may contain internal and coaxial heat recovery tubes creating an annular space filled in with a catalytic device. Both the external heat recovery through the catalyst tube outer surface and the internal heat recovery through the inner tube surface can be maximized by an enhanced catalytic device acting also as a heat transfer promoter in the process gas region. The apparatus provides enhanced and flexible heat recovery that permits to meet the request of minimum or none export steam production in one single apparatus, avoiding the need of a pre-reforming section and/or of a convective reformer downstream.

  • Patent number: 9776935
    Abstract: Disclosed is a process for the catalytic dehydrogenation of alkanes so as to form the corresponding olefins. The reaction mixture is subjected to membrane separation of hydrogen, in a separate unit. Preferably a plurality of alternating reaction and separation units is used. The process of the invention serves the purpose of reducing coke formation on the catalyst, and also of achieving a higher alkane conversion without a similar increase in coke formation. The process can also be used for the production of hydrogen.

  • Publication number: 20110150726
    Abstract: The present invention relates to the make of a heterogeneous gas-solid catalytic reactor operated in autothermic conditions, characterised by a flat temperature profile. This invention concurrently uses three actions to optimise the operation of the ATR reactor both in terms of energy and of catalytic activity: the adoption of a specifically formulated catalyst so as to favour a “direct type” reaction mechanism, the use and the make of the catalyst on a structured support with a high porosity and tortuosity, and characterised by high thermal conductivity and the adoption of a radial flow geometry catalytic bed.
