How Are Biofuels Used in Transportation?
Most vehicles run on gasoline and diesel. Diesel is a synthetic organic compound derived from crude oil. Gasoline is gasoline, dilute with water or air. Diesel is the commercial name for methanol, but hgh (a chemical compound of hydrogen) is also sometimes called gasoline. There are also two kinds of synthetic fuels, methylene chloride and ethylene glycol, which are made from petroleum and glycol, a by-product resulting from making soap.
Natural gas and petroleum coke have been in existence for decades.
The difference now is that petroleum coke is a by-product from the petrochemical industry and natural gas is here to stay. Natural gas and petroleum coke are both derived from the same natural resources, namely petroleum (petrol) and coal (natural gas), which are composed of molecules of carbon (C). They differ only in the amount of hydrogen contained within the molecule. Natural gas and petroleum coke have higher boiling points than gasoline and diesel fuel oil, respectively, though at a lower average density.
Ethanol has been around since the 1970s.
It has historically been used as an alternative fuel for tractors, semisubsidures, and diesel fuel trucks. Unfortunately, although it is cheaper than gasoline and diesel fuel oil, it still contributes to global warming because it is derived from petroleum. Because it is made from corn, it is technically not renewable, meaning that the supply will eventually dry up. Ethanol is available in three basic forms: ethanol liquid, ethanol gaseous, and gasolineification byproducts.
An alternative to Ethanol
is to blend ethylene and propane into a single solid block called Ethanol. This fuel has a much higher density than gasoline, so it burns cleaner. There are currently no Ethanol gas refineries in operation. However, Ethanol is beginning to slowly find its way into the marketplace as “flex-fuel” or as another type of motor fuel backed by federal research funding.
When crude oil is cracked and refined into gasoline,
some of the heat that results is transferred into the gasoline. Most modern cars are equipped with what is called an “oil cracking” technology, whereby some of the heat energy is transferred into the gasoline during the cracking process. The heat energy is not wasted, though, because it is instead converted into thermal energy during the final processing stages. Some modern-day refineries use mechanical cracking to achieve this end. The final step is to heat the gasoline once more to make it ready to be sold.
Biomass is the two major sources of nonrenewable natural gas and diesel fuel.
The natural gas that is produced from biomass is usually combusted in power plants to form either diesel or natural gas, but the bias is usually fed directly into the vehicle’s fuel system as a supplement to gasoline. Many governments have been exploring the potential for new technologies to replace fossil fuels such as gasoline and diesel for transportation shortly, and one such replacement technology is cellulosic ethanol.
