“…To address this issue, both the Federal Aviation Administration of the USA (FAA) and the Civil Aviation Administration of China (CAAC) have established airworthiness regulations mandating necessary measures to minimize fuel tank flammability [3]. Years of research have demonstrated that fuel tank inerting technology, which reduces the OC in the fuel tank ullage, is the most effective method for mitigating fuel tank flammability [4][5][6].…”

Oxygen-consuming inerting technology is expected to be the primary method for suppressing aircraft fuel tank fires and explosions in the next generation, with the catalytic reactor serving as its core component. However, the catalytic properties of the developed catalyst have yet to be thoroughly studied, and a primary reaction kinetic equation is needed to support further investigation of the reactor. Thus, this study focuses on the performance of the developed catalyst for RP-3 fuel vapor, with a test bench built to analyze its reaction kinetic characteristics. Initially, we tested the steady-state variation in the fuel vapor concentration (FVC) with fuel temperature and fitted an empirical equation, providing fundamental data for subsequent experiments. Subsequently, we studied the impact of critical parameters, such as the FVC, oxygen concentration (OC), CO2 concentration, and reaction temperature, on the reaction performance. The results demonstrate that the reaction rate is positively correlated with the FVC, OC, and reaction temperature, while CO2 has no impact on the catalytic reaction characteristics. Finally, a kinetic equation for the developed catalyst is summarized based on the experimental data, providing a fundamental equation for simulating research on the catalytic reactor and the oxygen-consuming inerting system.

The Impact on Emissions When an Engine Is Run on Fuel with a High Heavy Alcohol Content

This research reviews the impact on emissions from the engine fueled with the fuel containing a large share of bio-components, in particular with 30% n-Butanol. The research was carried out using a diesel engine. It has been shown that it is possible to achieve a double positive ecological effect concerning CO2 emissions. There was a decrease in CO2 emission from the engine with the fuel contained a significant share of bio-carbon. At the same time, NOx and Filter Smoke Number (FSN) emissions have been reduced together (FSN in large percentage). Usually, if NOx emissions are reduced, FSN increases, and vice versa. The paper shows also that the use of n-Butanol (bio, but nonfood) in the future is more effective than larger amounts of higher fatty acids methyl esters, although the full withdrawal of these esters seems unjustified.
