摘要： In a process for producing phenol and cyclohexanone, a feed comprising cyclohexylbenzene is oxidized to produce an oxidation reaction product comprising cyclohexyl-1-phenyl-1-hydroperoxide. At least a portion of the oxidation reaction product is then cleaved to produce a cleavage reaction product comprising phenol, cyclohexanone, and at least one contaminant. At least a portion of the cleavage reaction product is contacted with an acidic material to convert at least a portion of the at least one contaminant to a converted contaminant and thereby produce a modified reaction product. The oxidation reaction product may have at least 50 wt % of cyclohexylbenzene, no greater than 80 wt % of cyclo-hexyl-1-phenyl-1-hydroperoxide, and 0.1 wt % to 10 wt % of another hydroperoxide.

摘要： A feedstock containing at least 1 wt % butenes, at least 1 wt % pentenes, at least 1 wt % hexenes, at least 10 wppm C4 dienes, at least 10 wppm C5 dienes, and optionally at least 10 wppm C6 dienes can be selectively hydrogenated over a catalyst (e.g., a noble metal) to form a stream containing 100 wppm to 4000 wppm total dienes. The hydrogenated stream, and an olefinic recycle stream having less than 10 wt. % C1+ moieties, can be contacted with a molecular sieve catalyst, e.g., at a recycle to feed ratio between 0.1 and 3.0, at a WHSV of at least 1.0 based on olefin in the feed, and at a reactor ΔT no greater than 40° F. (22° C.), thus forming a reaction product that can then be separated into a distillate, e.g., having from 1 wt % to 30 wt % non-normal C9 olefins, and the aforementioned olefinic recycle stream.

摘要： Disclosed is a molecular sieve catalyst which contains molecular sieve-containing attrition particles and virgin molecular sieve, the attrition particles having been recycled from a catalyst manufacture process or from a reaction system. The catalyst can be used in a variety of catalytic reaction processes. A desired process is making olefins from an oxygenate feedstock. The recovery and use of the attrition particles in the catalyst is beneficial in minimizing waste, thereby reducing problems relating to both environmental and economic constraints.

摘要： Disclosed is a method for making olefin product from an oxygenate-containing feedstock. In the method, a silicoaluminophosphate molecular sieve catalyst is contacted with the oxygenate-containing feedstock in a reactor at an average catalyst feedstock exposure index of at least 1.0. The method produces lower coke yield and provides an olefin product which is low in C1-C4 paraffin content. The invention is particularly effective in producing an olefin product having a very low propane content.

摘要： Disclosed is a method of making an olefin product from an oxygenate feedstock comprising, contacting the feedstock in a reaction zone containing 15 volume percent or less of a catalyst, preferably a catalyst comprising a silicoaluminophosphate molecular sieve. In order to obtain the desired product content, i.e., an olefin product having a low level of by-products, conversion of the feedstock in the 15 volume percent or less reaction zone should be maintained between 80 wt % and 99 wt % at the conditions effective to convert 100 wt % of the feedstock when the reaction zone contains at least 33 volume percent of the catalyst material.

摘要： This invention comprises a method of producing ethylene rich product streams from a pressurized charge gas mixture of olefins and other components received from olefin generation/preparation processes. The method of this invention may eliminate the need for cryogenic fractional distillation and other special separation equipment operating at temperatures below -55.degree. F., and thus also potentially eliminate the refrigeration and heat exchange equipment needed to achieve those low temperatures. Alternatively, the method of this invention may eliminate the need for a circulating lean oil absorbant material, and thus also potentially eliminate the heat exchange equipment and reduces the refrigeration and fractional distillation load required to manage that material. In accordance with the process of this invention, a secondary ethylene rich product stream is produced at a rate and composition suitable for subsequent generation of a primary ethylene rich product potentially containing substantially no components having a boiling point at least as low as ethylene. Further, the secondary ethylene rich product stream may be suitable as feedstock in the production of ethylene derivatives, or be amenable to further concentration of ethylene using bulk separation techniques, or combinations thereof. Accordingly, the capital and operating cost associated with the manufacture of ethylene rich product streams from pressurized charge gas mixtures made by olefin generation processes may be significantly reduced through the method of this invention.
