  • Biodiesel Purification

Biodiesel as a biodegradable, sustainable and clean energy has worldwide attracted renewed and growing interest in recent years, chiefly due to development in biodiesel fuel and ecological pressures which include climatic changes. In the production of biodiesel separation and purification is a critical technology.
Biodiesel as a biodegradable, sustainable and clean energy has worldwide attracted renewed and growing interest in recent years, chiefly due to development in biodiesel fuel and ecological pressures which include climatic changes. In the production of biodiesel separation and purification is a critical technology for upgrading biodiesel quality.

SEPLITE®BD130 is a provenion exchange resin for purifying biodiesel.It can be used without any special pre-treatment, which greatly simplifies biodiesel purification. It functions as a desiccant, neutralizing agent and an ion exchanger to remove water, leftover reactants and by-products of the transesterification process, including soaps, glycerin, NaOH and organics.
Other Typical Applications
  • Ethylene glycol polishing
  • Caprolactam purification
  • Purification of polysiliconfor semiconductor
  • Removal of aldehydes from ethylene glycol
  • Weak acid refining, through separating strong acid and weak acid.
  • Caprolactam refining, through reducing matting, alkalinity and volatile alkali content
  • Preparing electronic grade hydrogen peroxide, through reducing organic carbon content
  • Alkyne production of 1,4 butanediol intermediates, through removing salt & silicon
  • Concentrated hydrochloric acid refining, through removal iron and zinc
  • Methanol refining, through removing for metal ions, basic nitrides

Advancing Ergothioneine Biosynthesis through Adsorption and Separation Technology

Sunresin has developed Uniform Particle Ion Exchange Resin using targeted research and development, advanced chromatographic equipment, and strict quality control, utilizing new synthetic biology technology. This resin is designed to address the impurities and high salt content of existing fermentation processes used to produce ergothioneine. It is used for chromatographic desalination, decolorization, and purification, achieving an inorganic/organic salt removal rate of over 95% in high salt systems, reducing conductivity to below 50μs/cm. Moreover, the uniform particle characteristic of the resin allows for lower pressure drop in the resin bed, larger online liquid processing capacity, lower resin breakage rate, and better impurity and salt removal compared to conventional resins. This results in higher yields and significantly improved production efficiency, while reducing production costs.
