Biodiesel
Soybeans are better for the soil than corn.
A hybrid car uses standard gasoline and electricity. A biodiesel car runs on a completely different fuel, such as ethanol. There are also other kinds of biodiesel that are being developed.
Ethanol evaporation can affect the efficiency of a chemical reaction by changing the concentration of reactants and products in the reaction mixture. When ethanol evaporates, the volume of the reaction mixture decreases, leading to a higher concentration of the remaining components. This can potentially alter the reaction rate and equilibrium, impacting the overall efficiency of the reaction.
Biofuels are produced from plants, ethanol, biodiesel, and several other things.
The chemical formula for biodiesel is C17H34O2. It is derived through a process called transesterification, where vegetable oils or animal fats are reacted with alcohol (usually methanol or ethanol) in the presence of a catalyst to produce biodiesel and glycerin.
the only ones I'm aware of are ethanol-gasoline and biodiesel
Biodiesel improves public health and the environment, and provides safety benefits. It also reduces greenhouse gas emissions better than gasoline, ethanol, and conventional diesel.
Vegetable Oil is used to make biodiesel, and corn is used to make ethanol for a gasoline substitute.
Alternative fuels like biodiesel, ethanol, natural gas, and hydrogen offer benefits such as lower greenhouse gas emissions, reduced dependence on fossil fuels, and potential for renewable sources. However, drawbacks include higher production costs, limited availability of infrastructure, and lower energy density compared to traditional fossil fuels.
While not as a chart, this is an idea about combustion energy values: Ethanol 77,000 Btu per gallon, Gasoline 125,000 Btu per gallon, Diesel 135,000 Btu per gallon and Biodiesel 130,000 Btu per gallon. Grades of fuel imply differences in composition and thus differences in combustion Btu values. Combustion values for ethanol will not depend on source of ethanol as long as ethanol content/composition is the same. Ali Hamza A_Hamza@yahoo.com
The iodine value of biodiesel gives an indication of the degree of unsaturation in the fatty acid chains present in the biodiesel. It is typically lower for biodiesel derived from saturated fats or oils, and higher for biodiesel derived from unsaturated fats or oils. Knowing the iodine value can help assess the oxidative stability and cold flow properties of biodiesel.
Ethanol burns differently than a mix of ethanol and water because water has a higher boiling point compared to ethanol. Water will absorb heat during combustion, which can lower the overall temperature and affect the efficiency of the burning process. This can lead to a slower and less complete combustion compared to pure ethanol.
