    摘要： The invention relates to a fluidized-bed reactor for polymerization of olefins, said reactor comprising an upper section of the reactor acting as a polymerization space in which olefin monomers are polymerized in a fluidized bed formed by polymerizing particles and a lower section of the reactor acting as a mixing space through which circulating gas removed from the top of the polymerization space is passed to the fluidized bed contained in the lower part of the polymerization space through a horizontal gas distributor plate in order to maintain the fluidized state of the bed, in which arrangement the circulating gas is passed to the lower section of the reactor via one or more inlet nozzles and the bottom section of the reactor is additionally provided with means for directing the circulating gas. At least part of said means for directing the circulating gas flow is comprised of flow control elements formed by plate-like surfaces perforated with a number of holes and located so that a major part of the gas flow is directed sideways below said means and a minor part of the gas flow is directed upwards to pass through said holes in said means.

    摘要： A method of reforming a gasification gas, in order to decompose the impurities comprised in the gas, and a use of a precious metal catalyst in the pre-reforming of gasification gas. The gas can be brought into contact with a metal catalyst in the presence of an oxidizing agent. The reformation can be carried out in several stages, in which case at least in one of the first catalytic zones a noble metal catalyst can be used, and in a secondary reforming stage which follows the first, preliminary reforming zone, the catalyst that can be used is a metal catalyst. Oxygen can be fed separately into each of the catalyst zones. The use of a noble metal catalyst can reduce the risk of deactivation of the metal catalysts and can increase the operating life of the catalyst.

    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.
