Butane is a hydrocarbon that is commonly used as fuel. Mixed with propane it is called LPG or liquefied petroleum gas. It is the most widely used alternative fuel due to its low carbon dioxide emissions, around 35\% less than diesel. Its use has not stopped growing in recent years and is expected to continue growing. This fuel has certain advantages, such as a lower price compared to gasoline, it causes less mechanical wear, hence its wide use in heavy vehicles and public transport, its storage can be done at lower pressures, which favors the installation of tanks in vehicles, making them less heavy and cheaper and lastly, LPG has a higher calorific value than gasoline. The combustion of n-butane (C4H10) with air follows the next reaction: 2C4H10(g)+13O2(g)8CO2(g)+10H2O(g) 1. Determine the air-fuel ratio for the complete combustion of n-butane. 2. Determine the composition of the products if a 50% excess air is introduced inside the chamber. 3. Which techniques could be used to control the products generated if particles with a diameter between 10 and 15m are also formed besides the gaseous compounds?
