    摘要: Processes and systems for C 3+ monoolefin conversion. In some examples, the process can include reacting a first mixture that includes C 3+ monoolefins and a first oxygenate to produce a first effluent that includes a first ether and 3+ olefin. A first product that includes the first ether and a first byproduct that includes at least a portion of any first di-C 3+ olefin and unreacted C 3+ monoolefins can be separated from the first effluent. A second olefin mixture, at least a portion of the first byproduct, and a second oxygenate can be combined to produce a second mixture. The second mixture can be reacted to produce a second effluent that includes a second ether and a second di-C 3+ olefin. The reaction of the second mixture can produce a greater amount, on a mole basis, of the second di-C 3+ olefin than the second ether.

    摘要: This invention is a process for producing diisobutylene from isobutylene. The process comprises first contacting a sulfonic acid resin with a reaction feed comprising isobutylene and tertiary butyl alcohol to produce a product stream comprising diisobutylene, isobutylene, tertiary butyl alcohol, and water. The product stream is distilled to produce a first overhead stream comprising diisobutylene and tertiary butyl alcohol. Water is separated from the first overhead stream, and the resulting isobutylene-enriched stream is recycled back to the reaction step. The first bottoms stream is distilled to produce a second overhead stream comprising tertiary butyl alcohol and a bottoms product stream comprising diisobutylene.

    摘要: The present invention relates to a process for the oligomerization of an olefin in the presence of a selectivity enhancing alcohol modifier wherein the modifier is formed by the reaction of olefin and water in a first reaction, and the thus formed modifier substantially free of water is separated and passed to a second reaction wherein olefin is oligomerized in the presence of the said modifier.

    摘要: A process is provided for the production of a gasoline blending fraction rich in isooctane by the dimerization of isobutylene using tertiary butyl alcohol modifier and isoalkane diluent; advantageously the isobutylene is derived from the dehydration of tertiary butyl alcohol and the isoalkane used as diluent in the dimerization is the product formed by hydrogenation of the oligomerization product.

    摘要: A flexible manufacturing system for selectively producing different alpha-olefins from ethylene includes: (a) a reaction section 18 with ethylene feed operative to oligomerize ethylene; (b) a catalyst feed system 12, 14, 16 comprising a plurality of independent homogeneous catalyst feeders connected with the reaction section for alternatively providing different selective homogeneous catalyst compositions to the reaction section; (c) an ethylene recycle column 22 coupled to the reaction section and adapted to receive crude product and unreacted ethylene therefrom, the recycle column being operative to separate ethylene and optionally lower oligomers from the crude product which are recycled to the ethylene feed to the reaction section, the ethylene recycle column being further operative to provide a crude product bottoms stream; (d) a catalyst removal section 20 coupled to the reaction section adapted to remove spent catalyst from the system; and (e) a first product separation column 24 connected to the recycle column receiving the crude product stream therefrom, the product separation column being operative to separate purified oligomer from the crude product stream. Optionally provided is a second product separation column 26.

    摘要: Fluorinated solid acids and supported fluorinated solid acids are used as catalysts for the polymerization of a feed stream containing at least one of pure monomoer, C5 monomers, and C9 monomers to produce hydrocarbon resins. Freely-associated water may be removed from the fluorinated solid acid catalyst and/or supported fluorinated solid acid catalyst prior to use. Resins with softening points (Ring and Ball) in the range of about 5 DEG C to 170 DEG C can be prepared. These catalysts offer advantages over the traditional Friedel-Crafts polymerization catalysts since the acid sites are an integral part of the solid. The fluorinated solid acid catalysts and supported fluorinated solid acid catalysts are relatively nonhazardous, reusable catalysts which eliminate or at least reduce contamination of the resulting resin products with acid residues or by-products.
