    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.

    Abstract: Disclosed is a dehydrogenation method that includes supplying a feed containing a hydrocarbon and steam into a dehydrogenation reactor containing a dehydrogenation catalyst, contacting the hydrocarbon and steam with the dehydrogenation catalyst to form a dehydrogenation product, wherein the dehydrogenation product comprises a dehydrogenated hydrocarbon, unreacted feed, steam and hydrogen, passing the dehydrogenation product through a membrane separator, and permeating hydrogen through a membrane positioned in the membrane separator. The hydrocarbon can be an alkyl aromatic and the dehydrogenated hydrocarbon can be a vinyl aromatic hydrocarbon, optionally the hydrocarbon can be an alkane and the dehydrogenated hydrocarbon can be an alkene.

    Abstract: This invention relates to a bismuth molybdate catalyst, a preparation method thereof, and a method of preparing 1,3-butadiene using the same, and to a bismuth molybdate catalyst, a preparation method thereof, and a method of preparing 1,3-butadiene using the same, in which 1,3-butadiene can be prepared through oxidative dehydrogenation directly using a C4 mixture including n-butene and n-butane as a reactant in the presence of a mixed-phase bismuth molybdate catalyst including α-bismuth molybdate (Bi2Mo3On) and γ-bismuth molybdate (Bi2MoO6). According to this invention, the C4 raffinate, containing many impurities, is used as a reactant, without an additional n-butane separation process, thus obtaining 1,3-butadiene at high yield. Unlike complicated multicomponent-based metal oxides, the catalyst of the invention has simple constituents and synthesis routes, and can be easily formed through physical mixing, and thus is very advantageous in assuring reproducibility and can be directly applied to commercial processes.

    Abstract: The present invention relates to a thermally integrated multi-zone process for conversion of alkanes to their corresponding alkenes, involving endothermically converting an alkane to its corresponding alkene by soft oxidant conversion in an endothermic reaction zone, in the presence of a weak oxidant, a suitable catalyst, and heat, to produce an intermediate product gas comprising the corresponding alkene and hydrogen. The weak oxidant may be, for example, carbon dioxide. The hydrogen is then removed from the intermediate product gas by contacting the intermediate product gas, in an exothermic reaction zone, with different second catalyst, and oxygen, to combust the hydrogen and produce a heated product stream comprising the corresponding alkene, water and heat. Heat is recovered from the heated product stream and recycled back to the endothermic reaction zone, while the resulting cooled product stream comprising the corresponding alkene may be subjected to further reaction and/or processing.
