AMBERLYST BD20 PDF

To produce biodiesel from high free fatty acid FFA oils, the esterification characteristics of two kinds of heterogeneous acid catalysts, Amberlyst 15 and Amberlyst BD20, were compared. When the FFA contents of oils were The activity of Amberlyst 15 was inhibited by the water produced during the esterification process, but the activity of Amberlyst BD20 was not similarly affected by water. In images obtained with a scanning electron microscope SEM , many pores were seen within the Amberlyst 15 catalyst, whereas Amberlyst BD20 showed few pores. Despite the fact that the pores of the catalyst play a role in increasing the number of active sites, Amberlyst BD20, which had fewer pores, was deemed to have more desirable performance in reducing the inhibition by water of the esterification of high FFA oils.

BD20 catalyst for the esterification of a variety of feedstocks containing a wide range of FFA concentrations. We will also discuss the long-term operability of the unit, design constraints, and recommendations for design improvements. BD20 catalyst. Skip to main content. Thursday, November 11, - pmpm. Sarafinas, A. Miller, C. Hanlon, R. Schultz, A. The use of biodiesel as a renewable energy resource that could be an economical alternative to fossil fuels is receiving great interest.

Biodiesel is produced by the transesterification reaction of triglycerides with methanol to produce fatty acid methyl esters FAME. Unfortunately, lower cost feedstocks for biodiesel manufacture often have unacceptably high levels of free fatty acids FFAs.

Presence of these FFAs lead to poorer process economics and increased problems in separation during the transesterification reaction. BD20 catalyst specifically designed for the effective and efficient conversion of FFAs to FAME, enabling biodiesel manufacturers greater flexibility with feedstocks for transesterification, with the added benefit of meeting increasingly challenging biodiesel quality standards.

According to Dr. Rajiv Banavali, Process Chemicals Research Manager, Rohm and Haas, this technology is significant for biodiesel producers because it enables the use of lower cost feedstocks, such as animal fats, crude vegetable oils, soap stock, and other more affordable high, free fatty acid oil and fat feedstocks. Kim Ann Mink, Vice President and General Manager, Ion Exchange Resins, Rohm and Haas, adds, "The process economics and biodiesel quality are far more favorable with this catalyst technology than other standard solid catalysts. We are pleased that we can support the state of Pennsylvania and, at the same time, further demonstrate how this technology will benefit biodiesel producers.
