  • Patent number: 9809739
    Abstract: The present disclosure relates to a method for regeneration of spent ion exchange resins to obtain regenerated ion-exchange resins. The regenerated ion exchange resins can efficiently reduce the total acid number (TAN) of highly acidic crude oils. The present disclosure particularly relates to a method of treatment of spent ion exchange resins using at least one non-acidic crude oil condensate and at least one polar organic solvent.
    Type: Grant
    Filed: August 19, 2014
    Date of Patent: November 7, 2017
    Assignee: RELIANCE INDUSTRIES LIMITED
    Inventors: Biswajit Shown, Swapan Ghosh, Asit Kumar Das, Suyog Subhash Salgarkar, Mukunda Madhav Baishya, Mitul Amrutbhai Ladani, Chirag Dalpatbhai Panseriya
  • Patent number: 9790175
    Abstract: In the present disclosure there is provided a process for obtaining di-sulfide oil having sodium level below 0.1 ppm wherein a stream comprising di-sulfide oil having sodium level 1 ppm, collected as a waste stream from LPG desulfurization unit, is passed through an alumina bed packed in a column at a pre-determined liquid hourly space velocity (LHSV) and at pre-determined temperature to obtain a treated stream comprising di-sulfide oil having sodium level below 0.1 ppm.

  • Publication number: 20070269867
    Abstract: A novel cytosolic 58 kd phosphoprotein induced during bone marrow stem cell (BMS) differentiation into dendritic cells (DC) during in vitro cultivation with the cytokine GM-CSF by addition of antisera to an 82 kd BM cell surface protein generating cultivatable dendritic progenitor cells (DP). Genes, methods for preparing them as well as early DP have been provided. Potential uses/advantages lie in the study of BM differentiation and innate immunity due to stimulatory/inhibitory DC, contribution of BMS and DP to inflammation during infection and carcinogenesis, tumor promotion/regression, identification of BM-derived blood cells, T-cell activation/regulation/tolerance and inflammation.

  • Publication number: 20060292163
    Abstract: This invention relates to a novel immunoadjuvant, an adjuvant component, and vaccines containing the adjuvant component. The adjuvant includes phytol or a phytol derivative. The adjuvant component, when combined with a soluble or particulate antigen, provides a vaccine with an enhanced ability to induce both humoral and cytotoxic immune responses while displaying reduced toxicity and/or adverse side effects over vaccines that include the antigen but without the benefit of this adjuvant component.
