摘要： Improved alkylation catalysts, alkylation methods, and methods of making alkylation catalysts are described. The alkylation method comprises reaction over a solid acid, zeolite-based catalyst and can be conducted for relatively long periods at steady state conditions. The alkylation catalyst comprises a crystalline zeolite structure, a Si/Al molar ratio of 20 or less, less than 0.5 weight percent alkali metals, and further having a characteristic catalyst life property. Some catalysts may contain rare earth elements in the range of 10 to 35 wt %. One method of making a catalyst includes a calcination step following exchange of the rare earth element(s) conducted at a temperature of at least 575° C. to stabilize the resulting structure followed by an deammoniation treatment. An improved method of deammoniation uses low temperature oxidation.

摘要： An alkylation process including an upfront isomerization zone is described. 100% n-butane or field butanes can be converted into a blend of approximately 60 wt % isobutane and 40 wt % n-butane in the isomerization zone. This blend can be used as the feed to all types of alkylation zones. It stabilizes the feed composition so that the dehydrogenation zone and alkylation zone always operate with the same feed.

摘要： An alkylation process and apparatus are described. The alkylation process includes pre-mixing a paraffin stream with an ionic liquid catalyst stream from a settler. The premixed paraffin and ionic liquid catalyst stream is mixed in a low-efficiency pump to form a paraffin and ionic liquid catalyst mixture. An olefin feed stream is introduced into a riser reactor. The paraffin and ionic liquid catalyst mixture is introduced into the riser reactor to form a reaction mixture comprising alkylate and the ionic liquid catalyst. The reaction mixture is separated in a settler into an ionic liquid catalyst stream and a hydrocarbon stream.

摘要： The invention relates to a process for purifying hydrocarbon mixtures, in which a contaminated hydrocarbon mixture comprising olefins having three to eight carbon atoms is at least partly freed of sulphur-containing contaminants by contacting it with a solid sorbent, the hydrocarbon mixture being exclusively in the liquid state during the contact with the sorbent. The problem that it addressed was that of virtually completely removing sulphur compounds present in the mixture without forming new sulphur compounds again at the same time. At the same time, 1-butene present therein was not to be lost in the purification of the mixture. Finally, the sorbent used was to have a high sorption capacity, be very substantially free of carcinogenic constituents and be readily available. This problem is solved by using a sorbent based on copper oxide, zinc oxide and aluminium oxide in a particular composition, and by conducting the purification in the presence of a small amount of hydrogen.

摘要： Methods and apparatus for refining feedstocks, such as crude or synthetic oil, and like feedstocks, are disclosed herein. In some embodiments, a reactor for refining a feedstock includes: a chamber having an inner volume to hold a liquid feedstock, a feedstock inlet port, a process gas inlet port, and an outlet port; a gas diffuser housed within the chamber and coupled to the process gas inlet port; and a radical generator coupled in fluid communication with the inner volume via the gas diffuser. In some embodiments, a method for refining feedstock includes: providing liquid feedstock to an inner volume of a reactor; flowing a radicalized process gas from a radical generator into the inner volume and into contact with the feedstock via a gas diffuser to fractionate the feedstock and produce one or more fractions of product in a vaporous mixture; and collecting a desired product from the vaporous mixture.

摘要： Continuous processes for monoalkylating aromatic compound with an aliphatic feedstock comprising aliphatic olefin of 8 to 18 carbon atoms per molecule are effected using at least 3 reaction zones in series, each containing solid alkylation catalyst with effluent cooling between reaction zones, each of which reaction zones is supplied a portion of the fresh aliphatic feedstock, such that the Reaction Zone Delta T in each reaction zone is less than about 15° C. The overall aromatic compound to olefin molar ratio is less than about 20:1. The alkylation product has desirable linearity and low amounts of dimers, dealkylated compounds and diaryl compounds even though a low aromatic compound to olefin molar ratio is used.
