BlankHi Everyone, Here is something of interest for all you folks interested in making and using ethanol in the biodiesel process. At www.uspto.com under patent number 4,695,411 there are 12 Examples of different ways to manufacture ethyl esters from different feedstocks. One Example uses cottonoil, another uses raw palm oil, several others use palm oil in different ways. One note of interest is the use of hydrated ethanol, that is to say ethanol with a water content of 1% to 60% !!! They use a first step acid transesterification and also use a regular base ( naoh or koh ) esterification with methanol or other alcohol as a second step. As always Patents are tough reading but the information in this Patent could yield some very helpful tips for those of you who want to use ethanol in your process. The Description section also says that the processes described can use vegetable or animal oil or greases. Another note of interest is the fact that the Patent was granted in September 1987 !!
