The Production of BioDiesel

We will begin by describing the nature of tri-glycerides, fatty acids, methyl esters, etc. After introducing these basic concepts, the class will move to the lab where they will participate in the trans-esterification (conversion to BioDiesel) of 25 gallons of WVO. The class will move in and out of the lab through the duration of the workshop as the production process continues through filling, titration, methoxide preparation, mixing, settlement, glycerin removal, water washing, etc. While in class we will also cover ASTM testing protocols and various quality and usage issues.

Clean Diesel/Common Rail Technology

This section will introduce the participants to the functional description of high pressure common rail systems, including high pressure delivery pumps, Piezo Injectors, advanced engine management systems and emission after-treatment system including Diesel Particulate Filters and Selective Catalytic Reduction NOx Converters. Practices that ensure the successful use of BioDiesel with these late model technologies will be emphasized. Much material from the SAE Symposium “light duty diesel emissions” will be presented. As time permits, the class will also be introduced to Tier 4 standards for non-highway engines and the leading proposals before Congress and the U.N. regarding CO2 emissions.
