DTG provides simultaneous differential thermal (DT) and thermogravimetric (TG) data. The TA-60WS
thermal controller provides advanced acquisition, analysis, and report functions which ensure
comprehensive simultaneous measurements. Installation and commissioning where straightforward
operations. The students were trained to use the instrument.
Task A. Investigation of the thermochemical and thermophysical properties of biofuels
and their neat fatty acids and neat methyl esters
Lower Heating Values of the
The fuels investigated in this study are:
ULSD#2 as reference fuel, Peanuts FAME, and
the Methyl Oleate that is the main fatty acid in
the Peanuts FAME and has been chosen
because it is the best candidate as reference
fuel for biodiesel. The higher heating value for
the tested fuels has been investigated in a
calorimeter presented in Figure 3. It is seen
that the LHV obtained decreases from the
value reference of ULSD#2 as the percentage
of biodiesel or methyl oleate in the blend
increases, Figure 4.
The GC-MS testing determined that the methyl
esters of stearic, palmitic, palmitoleic, and
myristic acid form the balance of the Peanuts
FAEM composition. All of these methyl esters
