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.

Adsorbent composition and a process for preparing the same

The present disclosure provides an effective and efficient process for the preparation of a dry chlorinated polyvinyl chloride (CPVC), comprising introducing chlorine gas into slurry of polyvinyl chloride in water to obtain a reaction mixture; irradiating the reaction mixture to obtain a product mixture comprising CPVC and water solution including unreacted chlorine gas and hydrogen chloride; filtering the product mixture to obtain a first mass; adding water to the first mass for extracting unreacted chlorine gas and hydrogen chloride to obtain an aqueous suspension, and filtering the aqueous suspension to obtain a second mass; passing nitrogen through the second mass to extract residual water solution to leave behind a third mass; and agitating the third mass in a high-speed mixer together with a neutralizing agent, and optionally with a stabilizer and a processing additive to obtain dry thermally stable CPVC with thermal stability in the range of 1000 seconds to 1500 seconds.

Process for the preparation of dry chlorinated polyvinyl chloride

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&#xb0; C. to 350&#xb0; 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.
