摘要： The invention concerns a process for preparing a tertiary alkyl ether product. The process comprises reacting the isoolefins of an olefinic hydrocarbon feedstock in a reaction zone (1-3) with an alkanol to form a reaction mixture, which is subjected to distillation in a first distillation zone (4). The bottoms product of the first distillation contains the ether(s), whereas the overhead stream contains unreacted alkanol and a mixture of light hydrocarbons. The overhead stream is subjected to a second distillation in a second distillation zone (15). The overhead product of the second distillation mainly contains the lightest hydrocarbons and a small amount of alkanol, and the bottoms product contains an essentially oxygenate-free hydrocarbon stream which can be used as such for alkylation. In order to increase the conversion of the process, a side drawoff is withdrawn from the second distillation zone (15) and recirculated to the reaction zone (1-3).

摘要： The invention relates to process for dimerizing olefinic hydrocarbon feedstock, to hydrocarbon compositions and to fuel components produced by the process. According to the invention, fresh olefinic hydrocarbon feedstock is fed to a reaction zone of a system including at least one reaction zone and at least one distillation zone. The olefinic hydrocarbon feedstock is contacted with an acidic catalyst in the presence of an oxygenate at conditions in which at least a part of the olefins dimerizes. The effluent from the reaction zone is conducted to the distillation zone where dimerized reaction product is separated from effluent, and at least one flow comprising oxygenate is withdrawn from the side of at least one distillation column. The flow is circulated from distillation zone back to dimerization. The reaction mixture is recovered and optionally hydrogenated to form a parafinic reaction product.

摘要： The invention concerns a process and an apparatus for preparing tertiary ethers. According to the process, C.sub.4 to C.sub.6 isoolefins and possibly heavier olefins contained in the feedstock are reacted with lower aliphatic alcohols, in particular methanol or ethanol, in a catalytic distillation reactor system in order to produce the corresponding ethers. According to the invention, the reaction between the isoolefins and the alcohols is essentially carried out in at least one reactor (5-7) of the kind, which is combined with a distillation column (3) intended for product separation, by conducting at least a part of the liquid flow of the column through the reactor and returning it to a lower tray than the one from which it was taken. At least half of cation exchange resin is placed in the side reactor (5-7). In the process according to the invention, the catalyst can be rapidly changed without stopping the process. In order to improve conversion additional alcohol can be fed to at least one of the side reactors.

摘要： The invention relates to a process for the treatment of a gas stream obtained from the production of polyolefins and containing unreacted compounds. According to the process, uncondensed compounds are removed from the gas stream and, when so desired, these compounds are directed to further treatment. According to the invention, the uncondensed compounds are separated from the gas stream by membrane separation. Thus the separation of gases is facilitated, since by coupling the membrane system in conjunction with distillation columns the distillation can be carried out at a substantially higher top temperature. By using the membrane system it is possible effectively to remove the lightest gases, which would otherwise accumulate in the process.

摘要： A process for dimerizing light olefinic hydrocarbons in a reaction zone containing a solid acidic catalyst. The process comprises recovering a reaction zone effluent which contains unreacted olefinic hydrocarbons, converting the unreacted olefinic hydrocarbons into an intermediate product in the effluent and separating the intermediate product from the effluent. By decomposing the separated intermediate product the unreacted olefinic hydrocarbons can be recovered and recycled to the reaction zone. By means of the invention, the yield of the product and the lifetime of the catalyst can be improved in a direct dimerization process of light olefins.

摘要： The invention relates to a process for preparing tertiary alkyl ethers. According to the process the feedstock containing hydrocarbons is fed to a catalytic distillation reactor system, in which the isoolefines, in particular the C.sub.4 to C.sub.7 isoolefines, of the feed are reacted with an alkanol in the presence of a cation exchange resin in order to produce tertiary alkyl ether products. The reaction product containing the ethers is removed from the distillation system as the bottoms product and, if necessary, it is subjected to an additional treatment for producing a gasoline component. The unreacted alkanol is removed as the overhead product of the distillation. According to the invention, the distillate withdrawn mainly contains an azeotrope of C.sub.4 hydrocarbons and alkanol, the C.sub.4 amount of which at least approximately corresponds to the C.sub.4 hydrocarbon concentration of the hydrocarbon feed, a substantial amount of the unreacted alkanol being removed in the form of said azeotrope. By means of the invention the need for a separate alkanol washing unit is eliminated in the apparatus which considerably reduces apparatus investment costs.
