I'm not Rohm and Haas Sale people but You can contact them via www.amberlyst.com
for my idea operation cost of Catalyst not more than 12.5 USD/ 1000 liter of Biodiesel from pre-Treated Palm Oil.

[U]Dear quemala

1.how much methanol you use in this process?
In the lab with batch reactor It's need more methanol about time to time save fuel between Pretreatment palm Oil/Methanol/save fuel Catalyst because It's to well mixing by magnetic bar.
2. You use dry methanol or wet methanol...or during the process you produce water so at the end of the esterification the methanol layer is wet?
Yes You can use wet MeOH MV=<2500 PPM but Dry MeOH baster. End of Reaction as same as sulfuric acid Catalyst Esterification, water was producing by Esterification Reaction betweeb FFA+MeOH = ME+H2O sothat If 15%FFA will create 3%Water mix with surplus MeOH.
3. You use Crude palm oil with a pretreatment..what kind of pretreatment you give to the oil?
Pretreatment Palm Oil mean half of Refine Palm Oil (Deguming+Bleaching+Filtering)
4. It's reusable the amberlyst resin??..it's expensive?? how much amberlite you use?
I think So because Acid Catalyst Esterification you can not use SST316 to make Reactor.
