摘要： The invention relates to 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 temperature 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： A process and apparatus for catalytically converting hydrocarbons to light olefins with a short contact circulating fluidized bed reactor system. The process comprises the steps of feeding a hydrocarbon feedstock into a reaction zone (1) containing a solid catalyst, contacting the hydrocarbon feedstock in the reaction zone (1) with the catalyst under conditions which favour catalytic conversion of hydrocarbons into light olefins, separating the reaction products obtained from the reaction zone (1) after catalytic conversion, recovering the catalyst, and regenerating the deactivated catalyst in a regenerator (3). According to the invention, the hydrocarbon feedstock is contacted with the catalyst in a circulating fluidized bed reactor (1) at a residence time in the range of 0.1 to 3 seconds. The process is used for preparing propylene, butylenes and pentenes and high octane, low benzene gasoline fraction by catalytic conversion of LGO, HGO, VGO or naphta, using conventional or improved FCC catalysts. The process can also be used for preparing propylene, isobutylene or isoamylene rich products by catalytic dehydrogenation from propane, isobutane or naphta, respectively, using conventional or improved dehydrogenation catalysts for fluidized bed service.

摘要： the present invention concerns a process for producing 2-butyl-2-ethyl-1,3-propanediol. According to the process, a reaction mixture is formed, containing 2-ethylhexanal and formaldehyde, into which a hydroxide compound is fed, whereby 2-ethylhexanal and formaldehyde are reacted to produce 2-butyl-2-ethyl-1,3-propanediol. According to the invention, the hydroxide compound is incrementally fed into the reaction mixture. Preferably, the hydroxide compound is fed at least at two input rates, in such a way that the heat production of the reaction between 2-ethylhexanal and formaldehyde immediately after each increase of the input rate of the hydroxide compound is at least almost the same. The invention allows for the production of BEPD in a controlled and safe manner, with excellent yields.

摘要： In the preparation of alkenyl succinic anhydride (ASA) from an olefinically unsaturated hydrocarbon and a maleic anhydride, additives are used in the preparation reaction in order to improve the yield of the product and to reduce side reactions. According to the present invention, quinone and hydroquinone derivatives as well as dialkyl sulfoxides and transition-metal acetylacetonate have such properties. The amounts to be added are approx. 0.01-2 mol % of the amount of maleic anhydride. The olefin is preferably a straight-chain alpha -olefin or a straight-chain or branched internal olefin having a chain length of 6-20 carbon atoms. The olefin may also be a polyolefin, in which case the preferred molecular weight is 900-1500. The preparation process may be of the batch type or the semi-batch type, and the maleic anhydride and the additive may be added in several batches or as a continuous feed which may be even or variable. The ASA obtained by the process may be used in particular as an additive in foods, for hydroxy sizing of paper, or as a dispersing agent in lubricants.

摘要： The application relates to a process for the oligomerization of olefins, preferably a hydrocarbon blend which contains 1-butenes and/or 2-butenes, for example the so-called Raffinate II stream and cyclic aromatic or alicyclic hydrocarbons, by means of BF3 and a cocatalyst. The aromatic hydrocarbon may preferably be styrene, alpha-methyl styrene, alkyl styrene, or a blend thereof, and the alicyclic hydrocarbon may be vinyl cyclohexane, vinyl cyclohexene, or a blend thereof. The cocatalyst is an aliphatic alcohol, carboxylic acid or inorganic acid. The oligomerization may be carried out with or without a medium, at a temperature above 0 DEG C, by adjusting the pressure to 1-10 bar by means of BF3 gas. The oligomer prepared by the process may be used as a solvent or an additive in fuels or lubricants, in surfactants, in white and cosmetic oils requiring extra purity, and in PVC and polyolefin plastics. In polyester and vinyl ester resins this oligomer can be used for replacing in part the monomer (e.g. styrene), thus reducing monomer evaporation and to inhibit shrinkage at the hardening stage, and it also improves the optical properties of the said resins.
