Description

Gel-type alcohol fuel composition {GEL-TYPE ALCOHOL FUEL COMPOSITION}

The present application relates to a gel alcohol fuel composition, and a method for producing the same.

The conventional alcohol fuel has various problems such as generation of toxic gas, lack of storage stability, short continuous duration, and danger of fire due to careless handling due to liquefaction during combustion. Paraffin-based solid fuel is used as a substitute for this, but it also has a drawback that its use is limited because of the high risk of fire when careless handling occurs because some of the components are liquefied during combustion.

Since a fuel composed of conventional alcohols has the above problems, it has been required to develop a semi-solid gelled fuel that has a suitable fluidity and can be burned directly by sublimation during combustion. In other words, gelled fuels having gelled alcohols are widely used in that they are unlikely to be easily leaked even if they are damaged, inadvertently handled or spilled, unlike solid or liquid fuels.

Prior literatures disclose fuels using higher fatty acid salts or dibenzylidene sorbitol, but higher fatty acid salts or dibenzylidene sorbitol are almost in the solid phase, especially in the case of higher fatty acid salts due to their high metal content, which influences the effects of moisture in the atmosphere. The amount of heat received was not able to achieve the desired calorie value, and its practical value is low because of the high amount of ash after combustion.

In the prior literatures, a fuel using nitrocellulose is disclosed, but since nitrocellulose itself is an explosive sensitive to heating or impact, it is extremely dangerous, and in summer, it is produced because there is always a risk of ignition or explosion due to decomposition heat at the same time as natural decomposition. The problem is that extreme care must be taken when using fuel or fuel.

In the prior documents, a fuel using an acrylic acid polymer is disclosed, and although the acrylic acid polymer is useful as an additive component in the preparation of gelled fuel in that it forms a good viscosity gel, it is possible to use a gel alcohol fuel by using this material. When prepared, there is a restriction that a relatively low molecular weight base such as ammonia must be used as the neutralizing thickener. In addition, these low molecular weight neutralizing thickeners are toxic and irritant, and their vapors irritate the skin and cause inflammation, so there is a drawback that care should always be taken when preparing gelled alcohol fuels or handling such fuels.

Moreover, these gelled alcohol fuels lack gel stability and generate toxic gases upon combustion, and gelled fuels with low calorie content are gelled by mixing alcohols having a large heat of combustion with two or more carbon atoms to increase calories. In this case, the addition of a low molecular weight neutralizing thickener not only results in poor gel formation ability, but also results in the fact that the resultant gel is partially destroyed at high temperatures.

In addition, there is a conventional technology related to the gel alcohol fuel in addition to the above, there is still a problem that is insufficient to be used in a field that requires a large amount of residual material after combustion and high calorific value.
