  • Publication number: 20230391623
    Abstract: The present invention relates to removal of catalytic metals from carbon nanomaterials bearing catalytic metals up to 15 wt % using an environmentally benign, non-mineral acid-based reagent solution. The reagent solution comprises a solid reagent selected from sodium persulphate or potassium persulphate or ammonium persulphate, wherein the solid reagent is dissolved in deionized water. The reagent solution enables removal of the metals present in the carbon nanomaterials without perturbing the structural integrity of carbon nanomaterials. The purification methodology disclosed in the present invention is suitable to use in energy storage, composite polymers, electromagnetic interference (EMI) shielding materials, conductive inks, conductive paints, field emission transistors, etc.

  • Patent number: 10759663
    Abstract: A catalyst composition for the production of carbon nanotubes (CNT) with controlled morphology is disclosed. The catalyst is represented by formula [(MxMny)Moz][binary metal oxide](100?(x+y+z)), where x is in the range 1 to 25 wt %, y is in the range 0.1 to 20 wt %, and z is in the range 0.0 to 10 wt %. Further M represents either iron or cobalt or nickel along with manganese and molybdenum supported on binary metal oxides comprising of boron, magnesium, aluminum, silicon, calcium, barium, and combination thereof. The CNT morphology can be tailor-made with the plural combination of nature of metal and promoters in appropriate proportions. The process yields the CNT with bulk density in the range of 0.01 to 0.20 g/cc, diameter in the range of 5 to 30 nm and purity greater than 95 wt %.

  • Patent number: 9932529
    Abstract: The invention discloses a rubber process oil and a process for manufacturing rubber process oils which are non-carcinogenic in nature. The process comprises of selectively producing Hildebrand solubility components enriched vacuum residue by selective distillation of reduced crude oil (RCO) to obtain minimum of 10 vol % boiling components in the range 490° C. to 50° C., which leads to higher solubility of rubber process oil with an aniline point of less than 70° C. and with extremely low concentration of selective polycyclic aromatics which makes the 15 product non-carcinogenic.
