摘要： A process combination is disclosed to reduce the aromatics content of a key component of gasoline blends. Paraffins contained in catalytic reformates are conserved and upgraded by separation and isomerization, reducing the reforming severity required to achieve a given product octane with concomitant reduction in paraffin aromatization and cracking. Light reformate may be separated and isomerized, and heavier paraffins are separated from the reformate by solvent extraction or adsorption; the recovered heavy paraffins are isomerized, optionally at a substoichiometric hydrogen ratio. A gasoline component having a reduced aromatics content relative to reformate of the same octane number is blended from the net products of the separation and isomerization steps.

摘要： A processing step is added to an existing catalytic reforming unit to increase the yield of aromatic product. The additional processing comprises separation of product from the reforming unit into an aromatic concentrate and a low-octane recycle stream which is upgraded by aromatization. The separation preferably is effected using a large-pore molecular sieve, and the aromatization with a nonacidic L-zeolite contained within the hydrogen circuit of the existing catalytic reforming unit.

摘要： A combination isomerization and liquid phase adsorptive separation process is given increased efficiency and cost effectiveness by the elimination of a column for the separation of desorbent material from selectively retained components. By decreasing the ratio of normal paraffin desorbent to the selective pore volume circulation rate, the extract column can be eliminated without providing other means for the rejection or recovery of desorbent material. This reduction in the ratio of normal paraffin desorbent to selective pore volume circulation rate has been found not to decrease the recovery from the adsorption section. The elimination of the column provides a substantial decrease in the cost of the equipment to operate a combination isomerization zone and liquid phase adsorption section. In an alternate arrangement, the extract column is replaced with a deisohexanizer column. The deisohexanizer column can be used to produce a C.sub.5 -C.sub.6 product stream having research octane numbers of 93 or greater.
摘要翻译：组合异构化和液相吸附分离方法通过消除用于将解吸剂材料与选择性保留的组分分离的柱来提高效率和成本效益。通过降低正常石蜡脱附剂与选择孔体积循环速率的比例，可以消除萃取柱而不提供用于排除或回收解吸材料的其它方法。发现正常石蜡脱附剂与选择性孔体积循环速率之比的这种降低不会降低吸附段的回收率。柱的消除大大降低了操作组合异构化区和液相吸附段的设备的成本。在替代布置中，萃取柱用脱乙酸酯柱代替。脱甲基塔可用于生产具有研究辛烷值为93或更高的C5-C6产物流。

摘要： A tubular reactor passes a flowing stream of reactants through a plurality of mixing devices that simultaneously provide indirect heat exchange of the reactants to improve the uniformity of reactant temperatures and concentrations. The mixing devices provide intimate mixing by passing the reactants through a plurality of narrow channels defined by parallel plate elements that channel a heat exchange fluid on their opposite side to provide the simultaneous indirect heat exchange. The heat exchange channels can have any desired degree of mixing intensity by providing irregularities in the channel walls or flow path that supply the desired degree of fluid shear. Preferably the mixing reactor provides a series of mixing devices with heat exchange along the length of the conduit flow path with space between the devices for remixing of the fluid reactants.

摘要： A combination of an etherification process and a process for the isomerization of linear alkenes to isoalkenes uses an adsorptive separation zone that receives an effluent fraction from the etherification reaction zone and separates the fraction at low efficiency to produce an isomerization feed stream comprising normal butenes and butanes, and a butane stream that is rejected from the process. The rejection of butanes at low efficiency reduces or eliminates the loss of butenes with the rejection of butane. A low efficiency adsorptive separation to reject butanes also benefits the isomerization process by inhibiting coking.

摘要： Embodiments of methods for co-production of linear alkylbenzene and biofuel from a natural oil are provided. A method comprises the step of deoxygenating the natural oils to form paraffins. A first portion of the paraffins is hydrocracked to form a first stream of normal and lightly branched paraffins in the C9 to C14 range and a second stream of isoparaffins. The first stream is dehydrogenated to provide mono-olefins. Then, benzene is alkylated with the mono-olefins under alkylation conditions to provide an alkylation effluent comprising alkylbenzenes and benzene. Thereafter, the alkylbenzenes are isolated to provide the alkylbenzene product. A second portion of the paraffins and the isoparaffins are processed to form biofuel.

摘要： An integrated process for the production of normal paraffins from a feed mixture of normal paraffins, iso-paraffins and aromatics is disclosed. The process integrates a normal paraffin sorption process and an aromatics sorption process. The normal paraffin product of the process of our invention meets the commercial requirements for production of detergents, including sufficiently-low concentrations of both iso-paraffins and aromatics. The process achieves these results without the need for two additional factionation columns that are necessary to prior unintegrated processes.
