摘要： This invention comprises a process for separating a saturated fatty acid from a feed mixture comprising saturated and unsaturated fatty acids, which process comprises contacting the mixture at separation conditions with a molecular sieve comprising a crystalline silica, thereby selectively retaining the saturated fatty acid. The saturated fatty acid is recovered from the molecular sieve by displacement at displacement conditions with a displacement fluid comprising a diluent soluble in the feed mixture and having a polarity index of at least 3.5. Amorphous silica is a preferred binder for the molecular sieve.

摘要： A fluid feed mixture, either liquid or gaseous in nature, may be subjected to a gas enrichment separation process. The process is effected by contacting the mixture with the upstream face of a mixed matrix membrane which comprises an organic polymer having a solid particulate adsorbent incorporated therein, the permeability coefficient of the organic polymer being compatible with the permeability coefficient of the adsorbent. The permeate which emanates from the downstream face of the membrane comprises a fluid product mixture in which the proportion of the first fluid component of the feed mixture, which possesses a greater steady state permeability in relation to the second fluid component, is greater than the proportion present in the original fluid feed mixture.

摘要： This invention comprises a process for separating a fatty acid from a mixture comprising a fatty acid and a rosin acid, which process comprises contacting the mixture at separation conditions with a molecular sieve comprising a crystalline silica, thereby selectively retaining the fatty acid. The fatty acid is recovered from the molecular sieve by displacement with a displacement fluid comprising an ester containing less than six carbon atoms per molecule. Once the rosin acid is removed from the feed mixture, the process is also effective in separating the fatty acids from each other, using the same molecular sieve and displacement fluid.

摘要： An improved adsorbent comprising a crystalline aluminosilicate, method of manufacture of the adsorbent and improved process for separating a component from a feed mixture comprising an aqueous solution of a mixture of different components, such as a mixture of saccharides. In the process the mixture is contacted with the adsorbent, which selectively adsorbs a component from the feed mixture. The adsorbed component is then recovered by contacting the adsorbent with a desorbent material such as water to effect the desorption of the adsorbed component from the adsorbent. There is an undesirable tendency for the silicon constituent of the crystalline aluminosilicate to dissolve in the aqueous system. The improvement to the adsorbent and process comprises the coating of the adsorbent with ethylcellulose which substantially reduces the undesirable dissolution. The adsorbent is manufactured by mixing together the uncoated precursor of the adsorbent with the organic polymer dissolved in a liquid organic solvent, and removing the solvent.
