摘要： In an embodiment, a method for decreasing reactor fouling in a steam cracking process is provided. The method includes steam cracking a hydrocarbon feed to obtain a quench oil composition comprising a concentration of donatable hydrogen of 0.5 wt. % or more based on a total weight percent of the quench oil composition; exposing a steam cracker effluent flowing from a pyrolysis furnace to the quench oil composition to form a mixture; and fractionating the mixture in a separation apparatus to obtain a steam cracker tar. In another embodiment, a hydrocarbon mixture is provided. The hydrocarbon mixture includes a mid-cut composition.

摘要： Processes are described for isomerizing one or more C14-C24 alpha olefins to produce an isomerization mixture comprising one or more C14-C24 internal olefins comprising contacting an olefinic feed comprising the one or more C14-C24 alpha olefins with a catalyst under isomerization conditions, wherein the catalyst comprises a microporous crystalline aluminosilicate having an MWW framework. The resulting isomerization mixture typically exhibits a low pour point with maintained biodegradability properties as compared to the olefinic feed, and is particularly useful in drilling fluid and paper sizing compositions.

摘要： A cyclohexane dehydrogenation process comprising a step of providing, as a benzene-containing stream, a vapor phase in equilibrium with a liquid phase at a condensation separation system; supplying benzene, hydrogen, and cyclohexane into a dehydrogenation reactor where at least part of the benzene supplied is from the benzene-containing stream. The use of a condensation separation system enables the control of the partial pressure of benzene in the material fed into the dehydrogenation reactor by controlling the temperature of the vapor phase, and hence the control of hydrogen to benzene molar ratio in the dehydrogenation reactor. The process results in a long life of the dehydrogenation catalyst due to reduced coking.

摘要： In a process for producing phenol, a cleavage feed comprising cyclohexylbenzene hydroperoxide is supplied to a cleavage reaction zone and a cleavage reaction mixture comprising the cleavage feed is contacted in the cleavage reaction zone with a solid acid catalyst under conditions effective to produce a cleavage effluent comprising phenol and cyclohexanone. The cleavage effluent is then divided into at least a cleavage product and a cleavage recycle and the cleavage recycle and a polar solvent is supplied to the cleavage reaction zone to produce the cleavage reaction mixture with the cleavage feed. Preferably, the polar solvent is combined with the cleavage recycle before being charged into the cleavage reaction zone.

摘要： In a process for producing cyclohexylbenzene, hydrogen and benzene are introduced to a first hydroalkylation reaction zone which contains a hydroalkylation catalyst and which is operated under at least partly liquid phase conditions sufficient to effect hydroalkylation of benzene to produce a mixed liquid/vapor phase effluent comprising cyclohexylbenzene and unreacted benzene, wherein at least a portion of the unreacted benzene is in the vapor phase. At least a portion of the effluent is cooled to condense a liquid phase stream containing at least some of the cyclohexylbenzene in the effluent portion and leave a residual stream containing at least some of the unreacted benzene and cyclohexylbenzene. At least a portion of the liquid stream is recycled to the first hydroalkylation reaction zone or to contact the mixed phase effluent exiting the first hydroalkylation reaction zone. Other methods of cooling the reaction effluent are disclosed.

摘要： Processes and systems for upgrading a hydrocarbon feed. The process can include feeding a hydrocarbon feed, catalyst particles, and molecular hydrogen (H2) into a separation zone. The hydrocarbon feed and H2 can be contacted in the presence of the catalyst particles under hydrotreating conditions in the separation zone that can include contacting under a total pressure of less than 3,500 kilopascals-gauge. The H2 can be fed into the separation zone at a rate of no greater than 270 cubic meters of H2 per cubic meter of the hydrocarbon feed, where the volume of H2 and hydrocarbon feed are based on a temperature of 25 C and a pressure of 101 kilopascals-absolute. A vapor phase hydrocarbon stream and a liquid phase hydrocarbon stream can be obtained from the separation zone. At least a portion of the vapor phase hydrocarbon stream can be fed into a pyrolysis reaction zone to produce a pyrolysis effluent.
