Multielement mixed liquid-like fuel and preparation method thereof

Abstract

The invention discloses multielement mixed liquid-like fuel. The multielement mixed liquid-like fuel is prepared from the flowing components in percentage by weight: A, 25-90% of liquid fuel, B, 5-55%of carbon-hydrogen containing combustible particles and C, 0.5-20% of water. The carbon-hydrogen containing combustible particles are obtained by separating a carbonaceous material source by the micro-mineral separation technique. The way that water and the carbon-hydrogen containing combustible particles are added in the liquid fuel is achieved for the first time, the obtained liquid-like fuel can have the solid content of 55% by weight, the fluidity is hardly affected, the liquid-like fuel can still be used in an industrial boiler or an internal combustion engine as fuel, and the structureand auxiliary equipment are not required to be transformed is realized for the first time. The carbon-hydrogen-containing combustible particles can be directly added to the liquid-like fuel, and the carbon-hydrogen containing combustible particles are not required to be dried, the situation that the process of mechanical scattering and dispersion is carried out again caused by agglomeration of thecombustible particles during drying is avoided, and the technique process is simpler and more convenient.

Description

technical field [0001] The invention belongs to the field of liquid fuel, and in particular relates to a multi-component mixed liquid-like fuel and a preparation method thereof. Background technique [0002] Liquid fuel is the main source of fuel for various boilers (including various industrial boilers in thermal power plants, chemical plants, and heating enterprises) and internal combustion engines (including internal combustion engines for vehicles, internal combustion engines for ships and aviation propulsion). People hope to increase the energy density of these fuels in order to increase heat generation or work efficiency, increase the mileage corresponding to the unit fuel storage tank of the transportation tool, and reduce the fuel transportation cost per unit calorific value. [0003] Existing methods to increase the energy density of liquid fuels and gaseous fuels include using fuels with higher density or higher unit calorific value, but the increase of fuel densit...

Problems solved by technology

[0004] One way to increase the energy density of liquid fuels is to add high-energy solid materials such as ultra-fine aluminum powder or high-energy solid carbonaceous material particles, but the problem with the former is that ultra-fine aluminum powder is expensive and prone to spontaneous combustion or explosion , is not safe, so it is only suitable for cost-insensitive military fields or aerospace fuel fields, and is not suitable for broader civilian industrial fields; the problem with the latter is: adding high-energy solid carbon to liquid fuels After adding solid material particles, the viscosity of the liquid fuel increases significantly, and the increase in the content of solid particles in the liquid fuel will cause a sudden change in the fluidity of the liquid fuel, changing from a fluid with a lower viscosity to a jelly-like fluid with a higher viscosity, and loses fluidity. There is no way to reuse it in industrial boilers or internal combustion engines
