Combustion Energy: A Measure of Stability in Alkanes and Cycloalkanes02:14

Combustion Energy: A Measure of Stability in Alkanes and Cycloalkanes

6.2K
The low reactivity in alkanes can be attributed to the non-polar nature of C–C and C–H σ bonds. Alkanes, therefore, were  initially termed as “paraffins,” derived from the Latin words: parum, meaning “too little,” and affinis, meaning “affinity.”
Alkanes undergo combustion in the presence of excess oxygen and high-temperature conditions to give carbon dioxide and water. A combustion reaction is the energy source in natural gas, liquified...

Fates of Pyruvate

8.3K
Pyruvate is the end product of glycolysis, where glucose is oxidized to pyruvate, simultaneously reducing NAD+ to NADH. Two molecules of ATP are also produced by substrate-level phosphorylation.
In aerobic organisms, pyruvate is metabolized via the citric acid cycle to produce reduced coenzymes NADH and FADH2. These coenzymes are then oxidized in the electron transport chain to produce ATP and, in the process, regenerate the NAD+ and FAD. As seen in some cell types and organisms, fermentation...

Area of Science:

  • Agricultural Economics
  • Chemical Engineering
  • Environmental Science

Background:

  • Global aviation industry seeks greenhouse gas (GHG) emission reductions.
  • Biojet fuel from sugarcane offers a sustainable alternative.
  • Current sugarcane mill operations in Brazil lack market flexibility.

Purpose of the Study:

  • Analyze optimal operation of integrated sugarcane mills for sustainable aviation fuel (SAF) production.
  • Determine economic viability and required incentives for biojet fuel production using Alcohol-to-Jet (ATJ) technologies.
  • Evaluate the impact of operational flexibility on profitability and guide policy development.

Main Methods:

  • Two-stage stochastic linear programming model.
  • Utilized historical time-series commodity price data from Brazil.
  • Conducted sensitivity analysis on conversion costs, operating costs, and SAF incentives.

Main Results:

  • Required premiums for current ATJ technologies range from $0.4 to $2 per liter.
  • Emerging ATJ technologies require premiums between $0.1 and $1.25 per liter.
  • A flexible sugarcane mill could generate an additional R$6 million annually, primarily from ATJ process flexibility.

Conclusions:

  • Biojet fuel production from sugarcane is feasible but requires specific economic incentives.
  • Operational flexibility in sugarcane mills and ATJ processes is crucial for profitability.
  • Findings inform biojet fuel policy and technology development in Brazil, with global applicability for supply chain expansion.
