摘要： Disclosed are novel processes for the production of cyclic imide compounds such as N-hydroxyphthalimide (NHPI). The processes may be particularly well-suited for commercial-scale production of cyclic imides such as NHPI. Such cyclic imide compounds are suitable for use as oxidation catalysts, and specifically may be used to oxidize cyclohexylbenzene to cyclohexyl-1-phenyl-1-hydroperoxide. Such an oxidation may be particularly useful in a process for the production of phenol and/or cyclohexanone from benzene via a process comprising hydroalkylation of benzene to cyclohexylbenzene, oxidation of the cyclohexylbenzene to cyclohexyl-1-phenyl-1-hydroperoxide, and cleavage of the cyclohexyl-1-phenyl-1-hydroperoxide to phenol and cyclohexanone. The cyclic imide production process may advantageously include water washing and reactant recovery steps to maximize purity and yield.

摘要： Processes and apparatus for preparing a liquid hydrocarbon product are provided. In one embodiment, a process for preparing a liquid hydrocarbon product includes thermally-treating a tar to produce a first tar composition and blending the tar composition with a utility fluid to form a tar-fluid mixture. The process includes separating the tar-fluid mixture to form a first lower-density portion and a first higher-density portion containing solids. The process further includes thermally-treating the first higher-density portion to form a thermally-treated first higher-density portion to convert at least a portion of the solids to liquid.

摘要： Disclosed are processes for abating 3-cyclohexenone from a feed mixture comprising cyclohexylbenzene, cyclohexanone, phenol, and 3-cylclohexenone and cyclohexanone, comprising feeding the feed mixture to a first distillation column and a hydrogenating a fraction from in the presence of a hydrogenation catalyst under hydrogenation conditions. Hydrogenation can be carried out in a hydrogenation reactor separate from the first distillation column or in a hydrogenation zone disposed inside the first distillation column.

摘要： Disclosed are processes for making cyclohexanone from a feed mixture comprising cyclohexylbenzene, cyclohexanone, phenol, 3-cylclohexenone and optionally 2-cyclohexenone, comprising feeding the feed mixture to a first distillation column and hydrogenating a fraction from the first distillation column in a hydrogenation reactor separate from the first distillation in the presence of a hydrogenation catalyst under hydrogenation conditions. A cyclohexanone-rich upper effluent comprising 3-cyclohexenone and 2-cyclohexenone at low concentrations can be obtained from the first distillation column.

摘要： Disclosed are a process for abating 3-cyclohexenone from a feed mixture comprising 3-cylclohexenone and cyclohexanone, comprising a hydrogenation step of contacting the feed mixture with hydrogen in the presence of a hydrogenation catalyst under hydrogenation conditions to obtain a hydrogenated mixture, cyclohexanone-containing products comprising 3-cyclohexenone and/or 2-cyclohexenone at low concentrations, and compositions of matter useful for making such cyclohexanone-containing products, particularly by using such processes.

摘要： In some examples, a vapor phase product and a liquid phase product can be separated from a heated mixture that can include steam and a hydrocarbon. The liquid phase product can be catalytically cracked in the presence of a fluidized catalyst to produce a catalytically cracked effluent. A bottoms product can be separated from the catalytically cracked effluent. The bottoms product can be hydroprocessed to produce a hydroprocessed product. For example, the bottoms product can be hydroprocessed under pre-treater hydroprocessing conditions to produce a pre-treated bottoms product and the pre-treated bottoms product can be hydroprocessed under bottoms product hydroprocessing conditions to produce the hydroprocessed product. A hydroprocessor heavy product can be separated from the hydroprocessed product. The vapor phase product can be steam cracked to produce a steam cracker effluent. A tar product and an upgraded steam cracker effluent can be separated from the steam cracker effluent.

摘要： Systems and methods are provided for increasing the portion of a pyrolysis tar fraction that can be hydroprocessed by using a physical particle size reduction process on at least a portion of the pyrolysis tar fraction. The physical particle size reduction process can reduce the percentage of particles in the pyrolysis tar fraction that have a particle size of 50nm or greater. It has been unexpectedly discovered that at least a portion of the particles having a size of 50nm or less, can be effectively hydroprocessed to form products of greater value while still reducing or minimizing the amount of fouling or plugging in a hydroprocessing catalyst bed. By increasing the number of particles having a size of 50nm or less, while selectively removing larger particles from the SCT fraction, a higher yield of hydrocarbon products can be achieved for a feed containing an SCT fraction. This can reduce or minimize the amount of particulates that are disposed of by incineration or another disposal method for fractions that have a lesser value.
