text: The hydrocarbons in crude oil are mostly alkanes, cycloalkanes and various aromatic hydrocarbons, while the other organic compounds contain nitrogen, oxygen and sulfur, and trace amounts of metals such as iron, nickel, copper and vanadium.
text: More specifically, the invention relates to a process for the separation of polar organic compounds containing sulfur, oxygen or nitrogen atoms from a feed mixture comprising naphtha and such compounds, which process employs a solid adsorbent which selectively removes the compounds from the feed mixture thereby producing a naphtha raffinate stream having a reduced content of such compounds.
text: In brief summary, this invention is, in one embodiment, a process for separating polar organic compounds containing sulfur, oxygen or nitrogen atoms from a naphtha containing those compounds which process comprises contacting the mixture at adsorption conditions with an adsorbent comprising a crystalline aluminosilicate, which exhibits relative selectivity for the compounds, thereby selectively adsorbing at least a portion of the compounds.
text: This invention is, in another embodiment, a process for separating polar organic compounds containing sulfur, oxygen or nitrogen atoms from a feed mixture comprising naphtha and those compounds.
text: The feasibility of separating polar organic compounds containing sulfur, oxygen and/or nitrogen atoms from a feed mixture comprising those compounds and naphtha by selective adsorption of the compounds on the particular adsorbent disclosed herein, which was demonstrated by pulse test results, was confirmed by continuous testing in the laboratory-sized apparatus described above.
text: For the particular separation process of this invention where polar organic compounds containing sulfur, oxygen or nitrogen compounds are to be recovered in high purity as a raffinate component it is necessary that the zeolitic adsorbent possess selectivity for all of the compounds with respect to the naphtha so that the naphtha will be rejected rather than adsorbed by the adsorbent.
text: This example illustrates the ability of this process when operated in its preferred embodiment as a continuous simulated moving-bed countercurrent flow type of operation to separate polar organic compounds containing sulfur, oxygen and/or nitrogen from naptha, i.e., to separate the thiophene, pyridine and phenol from the above described coal derived naphtha feed.
