  • Adsorbent composition and a process for preparing the same
    Patent number: 11452984
    Abstract: An adsorbent composition for reducing impurities of heat transfer fluids is provided and a process for the preparation of the same. The adsorbent composition comprises a layered double hydroxide in an amount in the range of 15 to 70 wt % of the total mass of the composition; alumina in an amount in the range of 30 to 85 wt % of the total mass of the composition; and optionally activated bauxite in an amount in the range of 15 to 50 wt % of the total mass of the composition. The adsorbent composition is economical and eco-friendly, having feed processing capacity in the range of 58 to 600 gm/gm.
    Type: Grant

  • Process for reducing total acid number of heat transfer fluid
    Patent number: 11053446
    Abstract: The present disclosure relates to a process to reduce total acid number (TAN) of a heat transfer fluid. The process comprises contacting the heat transfer fluid with an adsorbent composition at a temperature in the range of 50° C. to 350° C. and a pressure in the range of 1 bar to 10 bar to obtain a treated heat transfer fluid having total acid number (TAN) in the range of 0.003 to 0.03 and pH in the range of 6 to 7.5, wherein the adsorbent composition is provided in a fixed bed and the heat transfer fluid is passed through the fixed bed comprising the adsorbent composition at a liquid hourly space velocity (LHSV) in the range of 0.5 per hour to 10 per hour.
