Hydrocarbons. Hydrocarbons are organic molecules consisting entirely of carbon and hydrogen. They make good fuels because their covalent bonds store a large amount of energy, which is released when themolecules are burned (i.e., when they react with oxygen to form carbon dioxide and water).

What is H C ratio? Dear Li. High H to C ratio means higher hydrogen molecules in the fuel. As you know, hydrogen has the highest burning velocity between all fuels weather gases orliquids.

How does oxygen affect heat content? When a fuelis burned, oxygen in the combustion air chemically combines with the hydrogen and carbon in the fuel to form water and carbon dioxide, releasing heat in the process. An increase in oxygen in the combustion air can reduce the energy loss in the exhaust gases and increase heating system efficiency.

Why are hydrocarbons bad? All of these substances contribute to the greenhouse effect, and the depletion of the ozone layer. They also reduce the photosynthetic ability of plants, increase cancer rates in humans and animals, and increase the risk of respiratory illness. The most well-known and document dangerous of hydrocarbons is oil spills.

How are hydrocarbons obtained? Hydrocarbons are chemical compounds that contain the elements carbon and hydrogen only. They are compounds that are obtained from the fossil fuel crude oil by a process called fractionaldistillation.
