  • Patent number: 7566429
    Abstract: The present invention relates to an atmospheric pressure, reactive separation column packed with a solid acid zeolite catalyst for producing cumene from the reaction of benzene with propylene. Use of this un-pressurized column, where simultaneous reaction and partial separation occur during cumene production, allow separation of un-reacted, excess benzene from other products as they form. This high-yielding, energy-efficient system allows for one-step processing of cumene, with reduced need for product purification. Reacting propylene and benzene in the presence of beta zeolite catalysts generated a selectivity greater than 85% for catalytic separation reactions at a reaction temperature of 115 degrees C and at ambient pressure. Simultaneously, up to 76% of un-reacted benzene was separated from the product; which could be recycled back to the reactor for re-use.

  • Publication number: 20090136397
    Abstract: Disclosed is an optimized process and apparatus for more efficiently and economically carrying out the liquid-phase oxidation of an oxidizable compound. Such liquid-phase oxidation is carried out in a bubble column reactor that provides for a highly efficient reaction at relatively low temperatures. When the oxidized compound is para-xylene and the product from the oxidation reaction is crude terephthalic acid (CTA), such CTA product can be purified and separated by more economical techniques than could be employed if the CTA were formed by a conventional high-temperature oxidation process.

  • Publication number: 20090129992
    Abstract: A reactor is provided to produce compounds comprising at least one neutral, positive, or negative increased binding energy hydrogen species having a binding energy greater than the binding energy of the corresponding ordinary hydrogen species, or greater than the binding energy of any hydrogen species for which the corresponding ordinary hydrogen species is unstable or is not observed; and at least one other element. The reactor comprises a vessel containing an electron source and a source of increased binding energy hydrogen atoms having a binding energy of about 13.6 ? ? eV ( 1 p ) 2 where p is an integer greater than 1. Electrons from said electron source react with increased binding energy hydrogen atoms from said source in said vessel thereby producing said compounds. The source of increased binding energy hydrogen atoms may be a hydrogen catalysis cell selected from a group consisting of an electrolytic cell, a gas cell, a gas discharge cell, and a plasma torch cell.

  • Publication number: 20090124841
    Abstract: In producing C2-C4 olefins, in particular propylene, from an educt mixture containing steam and oxygenates, such as methanol and/or dimethyl ether, the educt mixture is reacted in a reactor on a catalyst to a reaction mixture comprising low-molecular olefins and gasoline hydrocarbons, which in a first separating device is separated into a mixture rich in C5? olefins, a mixture rich in C5+ gasoline hydrocarbons, and an aqueous phase. To increase the yield of propylene the mixture rich in C5+ gasoline hydrocarbons is supplied to a second separating device, in which the aromatics contained in the mixture are separated. The residual stream largely free from aromatics is at least partly recirculated to the reactor.

  • Patent number: 7531147
    Abstract: Disclosed is a shell-and-tube reactor that may be used for fixed-bed catalytic partial oxidation, the reactor being characterized by including at least one reaction zone of a first-step reaction zone for mainly producing unsaturated aldehydes and a second-step reaction zone for mainly producing unsaturated acids, wherein at least one reaction zone of the above reaction zones comprises two or more catalytic layers; each of the catalytic layers is packed with a formed product of catalyst that is different in pore density and/or pore size in a catalytically active component; and the pore density and/or pore size is controlled in such a manner that specific surface area of the catalytically active component increases from the inlet of the reactor to the outlet of the reactor. A method for producing unsaturated aldehydes and/or unsaturated fatty acids from olefins using the same reactor is also disclosed.
