Tulsion T-45 BD MP is a premium grade, solid acid catalyst based on a cross-linked polystyrene matrix containing sulfonic acid groups.  Tulsion T-45 BD MP is manufactured using controlled particle size synthesis and is used for many process applications.

The first step in biodiesel production involves esterification of fatty acids and trans-esterification of  triglycerides, commonly found in raw oil feedstocks.  This process yields a fatty-acid-methyl-ester or “biodiesel” component in the hydrophobic phase and a gylercine component in a hydrophillic phase. 

In the purification step, Tulsion T-45 BD MP is used to remove trace levels of glycerine and soaps from the biodiesel exhibiting high conversions with excellent physical, chemical stability and operating characterstics. T-45 BD MP can be used in a wide  range of temperature and pH conditions.
