摘要： Dual desorbent composition and/or dual temperature technique, when employed in a simulated moving-bed adsorption-desorption separation system embedded with a solid sorbent comprising certain sieves, e.g., Rb-exchanged Type X crystalline aluminosilicate sieve, which preferentially adsorb ethylbenzene, entails an improved separation and recovery of ethylbenzene from C.sub.8 aromatic feedstreams as sorbate product. Further, certain specific sieves, which preferentially adsorb xylene isomers, i.e., orthoxylene, metaxylene and paraxylene, may also be employed, in said simulated process utilizing the dual desorbent composition and/or the dual temperature concept, in order to effect the improved separation and recovery of ethylbenzene from its C.sub.8 aromatic isomers as raffinate product.

摘要： Dual desorbent composition and dual temperature techniques as improvements for simulated moving-bed adsorption-desorption separation processes whereby certain hydrocarbons can be separated from mixtures containing various unsaturated and/or saturated aliphatic and/or aromatic hydrocarbons. The dual desorbent composition technique is implemented by employing a strong desorbent stream in the desorption zone and a weaker desorbent stream in the rectification zone of a simulated moving-bed countercurrent adsorption-separation system; while the dual temperature concept envisions the temperature differentiation between the desorption zone and the remaining zones of said separation system in order to both minimize the desorbent requirement and enhance the purity of the separation products. A combined use of both the dual desorbent composition and the dual temperature techniques can further improve the performance of said simulated moving-bed system.

摘要： Simulated moving bed processes for the separation of C.sub.8 aromatic isomers using molecular sieve adsorbents are improved by the use of meta-diisopropylbenzene as the eluting agent. The invention describes a process for continuously separating, in a liquid phase, components of the feed mixture by contacting said feed mixture with a solid sorbent and utilizing a simulated countercurrent flow system wherein a liquid stream flows through serially and circularly interconnected desorption, rectification and sorption zones. In such a process the flow of liquid stream is interrupted between both the desorption and rectification zones and a first portion of effluent from the desorption zone, a portion being rich in sorbate may be directly circulated and a second portion, the same comprising sorbate of high purity and desorbent may be fed to a distillation apparatus from which one portion of the sorbate distillate may be circulated as reflux to the rectification zone to maximize the sorbate product purity at reduced costs and another portion is recovered as product. The present improved process is conducted using meta-diisopropylbenzene as a desorbent either alone or in combination with inert diluents such as paraffins. This embodiment provides a more effective separation of paraxylene and ethylbenzene peaks, thus increasing paraxylene recovery and at the same time reducing the amount of recycle and further ethylbenzene-paraxylene separations such as distillations and the like. This better separation allows more efficient use of the adsorbent bed and/or lower ratios of eluting materials to C.sub.8 aromatic feed which results in a more economic process.CROSS-REFERENCE TO RELATED APPLICATIONThis application is a Continuation-In-Part application of Ser. No. 457,056, filed Apr. 1, 1974 and now abandoned.

摘要： In a liquid chromatography commercial process for the separation of two or more components contained in admixture in a feedstream including the steps of (a) contacting the feedstream mixture containing the components to be separated with a bed of crystalline aluminosilicate adsorbent at conditions to effect the selective retention of two or more of the components by said adsorbent, (b) passing through said bed an eluent selected from the group consisting of aromatics and substituted aromatics, (c) increasing the strength of the eluting agent in the liquid carrier during the operation of the steps (a) and (b) above, (d) recovering from said bed a stream or streams containing at least a portion of the less selectively adsorbed components, and (e) recovering a stream substantially enhanced in concentration of said selectively adsorbed components relative to other components of feedstream wherein the improvement comprises preheating the eluting agent of step (c) above prior to passing it through said bed at temperatures of at least 160.degree. C., to thereby effect the desired separation under conditions that cause substantially lower elution volume to feed ratios. The improved liquid chromatography process is particularly applicable to the separation of paraxylene and ethylbenzene from a C8 aromatic isomer mixture containing ethylbenzene. The above process when operated with the eluting agent preheating step at temperatures of about 160.degree. C or higher causes temperature waves to flow through the bed with the final peak of each feed slug being eluted with the hotter eluting agent-carrier mixture, thus providing lower elution volume to feed ratios and thereby producing paraxylene more economically.

摘要： Dual desorbent composition and dual temperature techniques are provided as improvements for a simulated moving bed adsorption-desorption separation process which help reduce total desorbent requirements. The invention describes a process for continuously separating, in a liquid phase, components of a C.sub.8 aromatic feed mixture by contacting said feed mixture with a solid sorbent and utilizing a simulated countercurrent flow system wherein a liquid stream flows through serially and circularly interconnected desorption, rectification and sorption zones. One of the embodiments envisioned in the present improved process is directed to the employment of two desorbent streams of different strengths. This embodiment minimizes total amount of desorbent requirements by using a strong desorbent stream in the desorption zone and a suitable weaker desorbent stream in the rectification zone to achieve the desired separation. In another embodiment, the concept of temperature gradient is utilized to increase the desorbing power of the desorbent employed. Such an embodiment is carried out by providing a means of heating the desorbent stream prior to its introduction to the desorption zone and thereafter removing any residual heat before the desorbent stream passes to the rectification zone by means of a heat exchanger. Further, both the dual desorbent composition and the dual temperature techniques can be also simultaneously employed as another embodiment.
