Did you have experience about Amberlyst™ catalysts for Esterification process to convert FFA to Methyl Ester

Representatives from R&H were at the NBB conference. There was a display in the booth showing a R&H reusable catalyst being used in the esterification of FFA to methyl ester process. The people in the booth said the catalyst was still being worked on and may be ready by summer for market introduction.
