    摘要: In an apparatus and method for improved operation of a catalytic reactor, a preferred reactor comprises a vessel having concentric first and second annular catalyst beds. Heat transfer fluid flows through expandable heat transfer U-tubes passing through the catalyst beds, either concurrently or countercurrently with respect to the flow of process gas through the catalyst beds. This arrangement delivers improved heat transfer between the process and heat transfer fluids and allows the heat transfer U-tubes to expand longitudinally to withstand the pressure differential between the process gas and heat transfer fluids.

    摘要: Disclosed are apparatus and methods for conversion of hydrocarbon feed streams into liquid products. One embodiment of an apparatus includes a pressure vessel that contains a synthesis gas production device, a synthesis gas conditioning device and a synthesis gas conversion device wherein the synthesis gas production device and the synthesis gas conditioning device are nested within the synthesis gas conversion device. One embodiment of a method includes providing a hydrocarbon feed stream and producing a synthesis gas stream from the hydrocarbon feed stream in a synthesis gas production device. Subsequently, the synthesis gas stream is conditioned by removing heat from the synthesis gas stream through a first hollow body into a reactant feed stream that is then fed into the synthesis gas production device. Finally, the synthesis gas stream is converted to form a liquid product stream.

    摘要: Gases which are rich in carbon monoxide are producted by a catalytic cracking of gaseous or vaporized hydrocarbons. A part of the hydrocarbons is combusted with an oxygen-containing gas which is added at a rate that is twice to ten times the stoichiometric oxygen demand. The combustion temperature are between 800.degree. and 1500.degree. C. The oxygen-containing combustion gas is admixed to the preheated remainder of the hydrocarbon and a mixture is producted which is at a temperature between about 700.degree. and about 1300.degree. C. That mixture is passed through a fixed bed consisting of a granular cracking catalyst. A high-CO product gas at a temperature between about 800.degree. and about 1150.degree. C. is withdrawn from the fixed bed.

    摘要: Each ozonization loop (1) which includes a compressor (2), an ozonizer (3), and a heat exchanger (8) for cooling the oxygen-ozone mixture, is associated with three cylinders (4,5,6) filled with silica gel. Each cylinder operates in succession in a cocurrent adsorption, in countercurrent desorption by a substitution gas, and in scavenging by taking off a part of the flow circulating in the loop. The scavenging flow is recovered and combined with the substitution gas. The substitution gas may be in particular impure nitrogen supplyed by an air distillation apparatus producing the necessary oxygen.
