Abstract:

 

Currently the biodiesel industry is suffering from high feedstock prices and poor availability of virgin oil feedstocks. High FFA feedstocks of vegetable and animal origin represent alternative low-cost feedstock materials. These high FFA feedstocks are difficult to process using conventional homogeneous catalysts such as H₂SO₄ and up until recently, no viable solid heterogeneous catalysts were commercially available. Amberlyst™ BD20, a FFA esterification catalyst recently developed by Rohm and Haas, shows very high conversion and long lifetime.

 

Abstract:

 

Glycerol generation in the transesterification of triglyceride oils represents close to 11% of total production yield. The glycerol issued from conventional biodiesel processes has a high salt content, typically 5 to 10% after neutralization. There are many traditional markets for purified glycerol and new applications are emerging as glycerol availability increases. Conventional techniques for purifying glycerol such as distillation and classical ion-exchange may not be the most appropriate. The Ambersep™ BD50 process, jointly developed by Rohm and Haas and Novasep, is a low-cost glycerol purification alternative. It is a flexible process that ensures the most cost-effective solution to meeting a given purity specification.
