  • Patent number: 10046970
    Abstract: A two-step sc-SWCNT enrichment process involves a first step based on selective dispersion and extraction of semi-conducting SWCNT using conjugated polymer followed by a second step based on an adsorptive process in which the product of the first step is exposed to an inorganic absorptive medium to selectively bind predominantly metallic SWCNTs such that what remains dispersed in solution is further enriched in semiconducting SWCNTs. The process is easily scalable for large-diameter semi-conducting single-walled carbon nanotube (sc-SWCNT) enrichment with average diameters in a range, for example, of about 0.6 to 2.2 nm. The first step produces an enriched sc-SWCNT dispersion with a moderated sc-purity (98%) at a high yield, or a high purity (99% and up) at a low yield. The second step can not only enhance the purity of the polymer enriched sc-SWCNTs with a moderate purity, but also further promote the highly purified sample to an ultra-pure level.

    Abstract: A method for retracting oil on a water surface, and a method for reducing the quantity of oil on an oil control boom are described. Spreading of oil can be reversed by reducing the surface tension of the seawater, for example by using a low concentration of a water-soluble surfactant, such as a non-ionic surfactant. A controlled amount of the surfactant may be continuously discharged at the inner-wall of a spill control boom surrounding the oil spill. The spilled oil is caused to retract away from the boom toward the center of the area encircled thereby, such that the oil layer becomes sufficiently thick to be more effectively removed mechanically. The surfactant also reduces the amount of oil on the spill control boom, whereby the boom can easily be removed from a remediated oil spill and reused at a later date without further cleaning.

  • Patent number: 9260672
    Abstract: The present invention provides a process for deep desulphurization of cracked gasoline with minimum octane loss of about 1-2 units. In this process full range cracked gasoline from FCC, Coker, Visbreaker etc is sent to Diolefin Saturation Reactor for selective saturation of diolefins. After saturation of diolefins, the stream is sent to Splitter for splitting into three cuts i.e Light Cut (IBP-70° C.), Intermediate Cut (70-90° C.) and Heavy Cut (90-210° C.). The Light Cut which contains majority of the high octane olefins and mercaptan sulfur is desulfurized with caustic treatment using Continuous Film Contactor (CFC). The sulfur in the Intermediate Cut is also predominantly mercaptans and the cut can be desulfurized by caustic treatment using CFC along with Light cut or separately desulfurized before being sent for isomerization. The Heavy Cut containing mainly thiophinic sulfur compounds is treated either by using conventional HDS process or reactive adsorption process.
