Please check some of my publication in Tribology Transactions and wear where I use DSC for that purpose
They are two different techniques. The calorimetric pump is used to determine combustion heats while the DSC is not a suitable technique to measure this heat. Depending on the type of sample, you can easily determine calorific capacities in DSC (you can see some of my publications)
I suppose that you look at heat of combution (calorific value) as understood by F. Fraga (he means probably "calorimetric bomb"). I have to look at Gabi Nehme papers (not easy to find...), but DSC is essentially designed to measure phase transitions (T and enthalpy). Determination of heats of combustion means that you characterize inital and final state, that may be realized after some extenvive work using a closed (bomb) system. With an open DSC cup I don't see how to resolve the combustion problem. J-F
I suggest that Dr. Gabi Nehme give the references of the most relevant papers he wrote on the matter. I did not find them (or have no access to siome editors) on the net.
I found these articles corresponding to the "concise" info given:
"The effect of FeF3/TiF3 catalysts on the thermal and tribological performance of plain oil ZDDP under extreme pressure loading" Gabi N. Nehme∗ University of Balamand, Balamand, El-Koura, Lebanon Wear 278–279 (2012) 9-17
Concerns thermal decomposition analysis by DSC
"Optimization of Extreme Load and Break-in Period in Plain ZDDP Oil with FeF3 Catalyst Using Design of Experiment and Fundamental Study under Different Speeds"
Tribology Transactions Volume 57, 2014 - Issue 6
Only the abstract is available on my site. The abstract says "Thermal decomposition of ZDDP is examined in the presence of powder and dispersed FeF3 using differential scanning calorimetry (DSC) and thermogravimetric analysis (TGA)...."
So these references are irrelevant to the problem of calorific value, if understood as heat of combustion, that is a transformation of a matter into CO2, H2O, and other oxidation products.
On the other hand, I think that there are (approximate) methods to evaluate the heat of combustion from the C, H, N, S... content, if known from elemental analysis, see for example:
- "The relationship between elemental composition and heat of combustion of microbial biomass" Applied Microbiology and Biotechnology January 1987, Volume 25, Issue 4, pp 305–312.
- "Biomass, biochar and hard coal: Data mining application to elemental composition and high heating values prediction"
Journal of Analytical and Applied Pyrolysis Volume 104, November 2013, Pages 153-160.
and many others...
I did not read in detail these papers. A literature search into a precise domain should be done for specific applications.
