    摘要: A process for converting an olefin feed to hydrocarbons suitable for fuel components or their feedstock. According to the process, an olefin feed, possibly together with another hydrocarbon feed, is contacted in a reactor with a catalyst in order to produce a hydrocarbon having at least one alkyl side chain. In the invention, the olefin feed is contacted with a particle-form fluidized catalyst in a circulating-bed reactor, wherein the catalyst forms the circulating bed of the reactor. When the operation is carried out in a circulating-bed reactor, the retention time of the feedstock is short. In this case, iso-olefins are formed quite selectively from n-olefins in isomerization. Since the useful life of the catalyst lengthens while the catalytic activity of the bed remains high for a long time, the conversion level also remains high. A long useful life of the catalyst is an economically highly significant advantage. In a circulating-bed reactor the regeneration of the catalyst can be carried out quite flexibly, and the operation of the reactor need not be interrupted for the duration of regeneration.

    摘要: The invention relates ro a method of converting hydrocarbons. According to the method, a gaseous or liquid hydrocarbon feed is passed into a circulating fluidized-bed reactor, wherein the feed is converted at a high temperatue under the influence of particulate matter kept in a fluidized state, and the converted hydrocarbon products are removed from the reactor in a gaseous phase. According to the invention, a circulating fluidized-bed reactor (1-3; 41-43) is used having an axially annular cross section and being equipped with a multiport cyclone (14,17; 52,63) for the separation of the particulate matter from the gas-phase reaction products. The reaction space comprises an intershell riser space (13; 50) formed between two concentrically located cylindrical and/or conical envelope surfaces. The separation of particulate matter from the gas-phase reaction products is performed by means of a multiport cyclone equipped with louvered vanes (14; 63).

    摘要: The invention relates to a method and apparatus for separating two phases from each other. According to the invention, a stream made up of at least two phases is directed to a separation apparatus, which comprises a separation container (25) and cyclones (26) arranged in the flow direction in parallel and in succession, the cyclones having each an elongate separation chamber wherein the phases are separated from each other. According to the invention, the cyclones used are multi-inlet cyclones (26), the total number of which is at least 10. The stream to be treated is directed to each multi-inlet cyclone (26) in a substantially radial direction. Through the placement of a large number of multi-inlet cyclones in parallel, a purification element resembling a filter is obtained. In comparison to a filter, continuous regeneration takes place in the element, in which case the pressure loss does not increase during operation, since solids do not reduce the cross-sectional area of the flow conduit inside the element.

    摘要: The present invention relates to a method and apparatus for separating particulate matter from a gaseous stream. According to the method, the gaseous stream containing the suspended particulates is passed into a separator apparatus which includes at least two multiple-inlet-multicyclones (16-16C), wherein the particulates are separated from the gas by centrifugal force. According to the invention, a separator apparatus is employed wherein at least two (16-16C) of the multiple-inlet cyclones are adapted to operate in parallel so as to form a multiple-inlet-multicyclone apparatus. The cyclone assembly according to the invention may be used as, e.g., the primary separator of an FCC unit, but more advantageously it serves as the secondary or tertiary separator of an FCC unit to remove “fines” from the flue gases of the preceding separation stages.

    摘要: The present invention concerns a process and an apparatus for thermal conversion of biomass and organic wastes. According to the invention, the feedstock is fed into a fluidized-bed reactor, wherein the feed is converted at an elevated temperature under the influence of particulate matter kept in a fluidized state by a fluidizing gas, the particulate matter is transferred from the reactor to a regenerator for regeneration and then recirculated to the reactor after the regeneration, and the converted hydrocarbon products are recovered from the reactor. Both the reactor and the regenerator comprise risers having an axially annular cross section and being equipped with multi-inlet cyclones for the separation of particulate matter. By means of the invention, it is possible to producer pyrolysis oil, the quality of which is higher than that of oil produced with the processes of the prior art. The incorporation of multi-inlet cyclones into the reactor configuration reduces gas velocities, reduces the physical size of the cyclone and shortens the residence time of gases in the cyclone.
