摘要： Adsorbents and methods for the adsorptive separation of para-xylene from a mixture containing at least one other C8 aromatic hydrocarbon (e.g., a mixture of ortho-xylene, meta-xylene, para-xylene, and ethylbenzene) are described. Suitable binderless adsorbents (e.g., formulated with the substantial absence of an amorphous material that normally reduces selective pore volume), particularly those with a water content from about 3% to about 5.5% by weight, improve capacity and/or mass transfer. These properties are especially advantageous for improving productivity in low temperature, low cycle time adsorptive separation operations in a simulated moving bed mode.

摘要： The present invention comprises a process for removal of oxygenates from a paraffin-rich or olefin-rich paraffin stream which comprises passing a feed stream, comprising one or more C10 to C15 feed paraffins or C10 to C15 olefin-rich paraffin stream and one or more oxygenates through an adsorbent bed comprising one or more adsorbents selected from silica gel, activated alumina and sodium x zeolites to remove essentially all of said oxygenates; and recovering said paraffins. A second adsorbent bed may be employed to more thoroughly remove these oxygenates.

摘要： Various chemicals such as pharmaceuticals and petrochemicals are chromatographically separated in pilot plant quantities using an apparatus comprising a number of chambers containing an adsorbent linked together with valving necessary to simulate the continuous countercurrent flow of the adsorbent and liquid phases. The apparatus preferably comprises five multiport rotary valves, each having at least one port for each column. The fifth rotary valve provides a serial interconnection between the columns and also ensures the desired unidirectional flow of fluid in the apparatus.

摘要： A process for separating a ketose from a feed mixture comprising a ketose and an aldose which process comprises contacting the mixture with an adsorbent comprising a X zeolite containing one or more selected cations at exchangeable cationic sites thereby selectively adsorbing a ketose from the feed mixture and thereafter recovering the ketose. Preferably, the ketose will be recovered by desorption from the adsorbent with a desorbent material.
