SUMMARY

The discussion focuses on locating enthalpy profiles for various hydrocarbons, specifically fuels such as petroleum, diesel, ethanol, methanol, and biodiesel. The user, an IB student, seeks reliable literature values to compare combustion results and analyze the by-products of these fuels. Key resources mentioned include the NIST Chemistry WebBook for thermochemistry data and Wikipedia for heat of combustion values. The user also inquires about studies on emission gases from alternative fuels, particularly CO2 and NOx emissions.

PREREQUISITES
  • Understanding of enthalpy and thermochemistry
  • Familiarity with combustion processes and fuel types
  • Basic knowledge of emissions and environmental impact
  • Ability to evaluate scientific literature and data sources
NEXT STEPS
  • Research NIST Chemistry WebBook for detailed thermochemical data
  • Examine Wikipedia's entries on heat of combustion for various fuels
  • Investigate studies on CO2 and NOx emissions from alternative fuels
  • Explore experimental methods for measuring combustion by-products
USEFUL FOR

This discussion is beneficial for IB chemistry students, researchers in fuel science, environmental scientists, and anyone interested in the combustion characteristics and emissions of various fuels.

Hi i am a IB student currently working on my extended essay in the field of chemistry and was wondering if anyone could suggest where i could find the enthalpy profiles for specific hydrocarbons including standard enthalpy changes for fuels such as: petroleum, diesel, ethanol, methanol, bio-diesel and any other fuels that i might be able to find literature values for.

the premis of the experiment is to examine how the fuel to air mixtures affect the power of the combustions and which fuels have the most violent explosions. What i need the the enthalpy profiles for is to examine the bi-products of combusting these fuels.

If i could get any suggestions it would be much appreciated because the only values i have currently are those recorded by other students and i would like my sources to have less error in them in order to compare my results to accurate literature vales.

any help would be much appreciated,
cheers

Here is an excellent government reference that should get you started

http://webbook.nist.gov/chemistry.html

search by name and click on thermochemistry data links.As for the fuels like gasoline and diesel I was lazy and used wiki

http://en.wikipedia.org/wiki/Heat_of_combustion

I'm not sure how reliable the sources are for the enthalpies of combustion for the fuels, but you can look up the source and determine for yourself.

thanks for the help

I was just wondering if anyone currently using this forum has done any enperimenting or knows of any experiments where the emission gasses of proposed alternative fules has been studies for example CO2 levels and NOx emissions has been studied. If you have please give me the heads up on them i would find them especially useful when making conclusions to my findings.

thanks
