The Fuel of the Future?

The Fuel of the Future?

More recently, ethanol has been considered a potential generator of biodiesel, though other materials yielding other types of biodiesel, and the world today betting on ethanol as gasoline superseded in the future, as humanity faces serious problems related to the issue of gases in the ozone layer, such as carbon monoxide (CO), and can have serious consequüências to future generations.


One of the main topics of discussion in the modern world is the role of energy in the survival and development of human civilization, and the risk of destruction of the environment by the indiscriminate use of energy. The energy can be generated in nuclear power plants and power plants, but much of the energy used today comes from burning fossil fuels, which are organic compounds, so the concern with the problems of energy is necessarily part of the consciousness of organic chemicals.

We know that fossil fuels (gasoline, natural gas) are important sources of energy and raw materials for the maintenance of life and civilization. However, they are not renewable resources, that is, will be exhausted in the near future, concern and decisions. In the future, we will rely on energy from nuclear fission - also non-renewable - energy and renewable resources, which can be replaced periodically by the seasonal growth of plants.

The concept of renewable energy comes from the following considerations: without the influence of humans, the Earth receives energy only from the sun and loses energy into space in a balanced process that keeps the average temperature constant of the energy received from the Sun is used by plans to transform CO2 and H2O in organic compounds, which are used by animals to regenerate energy CO2, also keeping constant the concentration of CO2 in the atmosphere, another part is used to turn water into steam or air to move, and then converted to heat in the rain, wind, waterfalls, etc.. The energy produced by hydroelectric dams, therefore, should not change the temperature of the earth, for it would even be transformed into heat in one way or another, and is renewable because water always restarts the cycle of evaporating and condensing, returning ace waterfalls, likewise, the energy produced by fuels such as ethanol (derived from the fermentation of sugarcane juice) is not an added energy to the environment, it would be transformed into heat in any wood and is renewable because it can be planted more cane to absorb solar energy and produce more ethanol.

Of cane sugar, a renewable resource, is obtained a fuel used in Brazil: the ethyl alcohol or ethanol (C2H5OH). Other vegetables rich in sugar, like sugar and fruit, starchy foods such as cassava, rice and corn, and cellulose such as wood - especially the eucalyptus - can also be used to produce ethanol.

Green Fleet tries to revive Proálcool

The kick to the reactivation of Proálcool was given by the government, through Law No. 9660. Among other things it established the "green fleet, forcing the replacement of the entire fleet of models to Federal alcohol within five years. The exceptions are tanks and troop carriers of the Army. Vehicles purchased with tax incentives should also be moved with the fuel (such as taxis), and groups of the consortium for the purchase of vehicles to have alcohol to a longer term.

Combustion

The alcohols in excess of oxygen, burn (complete combustion), producing CO2 and H2O. The clean combustion of alcohol contributes to the reduction of greenhouse gases and substantially reduce air pollution, minimizing their impact on public health.
