Product Specification

Modified Pelletized Adsorbent for Pharmaceutical & Coating Solvent Recovery

Product Introduction

The Modified Pelletized Adsorbent for Pharmaceutical & Coating Solvent Recovery is a high-purity inorganic adsorbent specifically designed for cyclic adsorption and recovery of organic solvents such as ethyl acetate, isopropanol (IPA), and methyl ethyl ketone (MEK).

Manufactured from refined composite oxides with a precisely controlled pore structure, this material offers high surface area, stable mechanical strength, and exceptional regeneration durability.
Its smaller cylindrical pellets (3–4 mm) provide improved contact efficiency and rapid mass transfer, making it ideal for pharmaceutical, coating, and fine chemical processes where high-purity solvent recovery and VOC emission control are essential.

Note: Specifications and particle sizes can be customized according to customer requirements.

Features

• High Solvent Adsorption Efficiency: Optimized micropore and mesopore distribution ensures excellent adsorption of polar and semi-polar organic solvents such as IPA and ethyl acetate.

• Superior Regeneration Durability: Maintains ≥ 90 % adsorption performance after more than 250 regeneration cycles under thermal or vacuum desorption conditions.

• High Purity & Safety: Non-carbon, low-dust material eliminates ignition risks and contamination of recovered solvents.

• Fine Pellet Size: Smaller cylindrical pellets enhance surface contact area and shorten adsorption/desorption cycles.

• Stable Mechanical Strength: Uniform pellets resist crushing and attrition in high-flow cyclic adsorption systems.

Applications

• Pharmaceutical Solvent Recovery: Used in closed-loop systems for recovery and reuse of isopropanol, and ethyl acetate in API and formulation plants.

• Coating & Printing Industry: Applied in VOC control and solvent recycling units for paints, inks, and varnishes.

• Fine Chemical Production: Ideal for solvent vapor recovery from reactors, distillation vents, and purification processes.

• Activated Carbon Replacement: Provides higher thermal resistance, cleaner regeneration, and longer operational life compared to traditional carbon pellets.
