Phenolic Or Toxic Oils Patents (Class 208/2)
  • Patent number: 11858892
    Abstract: A process of removing methanol, CO2, or both from a hydrocarbon stream is described. The process uses an adsorbent comprising binderless type 3A zeolite. The adsorbent has high methanol removal capacity and low olefin co-adsorption capacity, as well as low reactivity in an olefin stream. This allows reduced adsorbent loading while maintaining downstream catalyst performance and product quality. The adsorbent comprises a type 3A zeolite comprising less than 5% of a binder and an ion exchange ratio of 30% to 70%. The adsorption process can obtain an outlet methanol content of 1 ppmw or less.

  • Patent number: 9962681
    Abstract: An adsorbent having a microwave absorption property is provided. The adsorbent having an improved microwave absorption property, which has a core-shell structure including a silicon carbide bead disposed therein, and an adsorbing material disposed outside the silicon carbide bead, can be provided. Also, the adsorbent may further include a plurality of silicon carbide particles dispersed and disposed therein and having a diameter of 1 ?m to 10 ?m, and the adsorbing material may be ion-exchanged with a cation. Therefore, the adsorbent can be useful in improving desorption efficiency since the adsorbent may be rapidly heated by microwaves to reach the desorption temperature due to high reactivity to microwaves. Also, the adsorbent can be useful in maintaining full adsorption capacity without having an influence on adsorption quantity since the silicon carbide bead is disposed in the inner core of the adsorbent.

  • Patent number: 5028543
    Abstract: A method for measuring the halogenated organic compound content, e.g., polychlorinated biphenyl ("PCB") content, of soil samples may effectively be carried out with an inexpensive, disposable (that is, single-use) field test kit. The method includes contacting a weighted soil sample suspected of containing PCB or some other organohalogen contaminant with a pre-mixture of water and an organic solvent in which water is slightly soluble. The water extracts any inorganic halides which may be present and would adversely affect the accuracy of the test. The organic solvent wets the moist soil sample sufficiently to extract any PCB therein. The resultant organic solvent phase is separated from the soil sample and aqueous phase, dried by passage through a moisture-adsorbent material to remove or at least greatly reduce its moisture content, and analyzed by means of a color-change titration to determine halide content, and thereby the PCB (or other organohalogen) content, of the soil sample.

    Abstract: An improved creosote wood preservative is produced that has a reduced crystal content, a light color and that makes a creosote-pentachlorophenol preservative less corrosive to metals. This improved creosote is produced by mildly hydrogenating a conventional coal tar creosote to reduce the aromaticity index, I.sub.A, by 10-62%. This is accomplished by hydrogenating the creosote at a temperature in the range of 250.degree.-450.degree.C. in the presence of a sulfur resistant hydrogenation catalyst.
