  • 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
  • Propane refining, through removing metal ions, basic nitrides
