Problems solved by technology

[0004] One way to increase the density of liquid fuels or gaseous fuels is to add high-energy solid materials such as ultra-fine aluminum powder to them, but ultra-fine aluminum powder is expensive and prone to spontaneous combustion or explosion, which is not safe, so it is only suitable for low-cost applications Insensitive military field or aerospace fuel field, not suitable for broader civilian industrial field

Embodiment 1

[0041] This example illustrates the preparation of low-sulfur and low-ash ultrafine carbonaceous material particles.

[0042] The source of the carbonaceous material used is peat with a mineral content of 30wt%, which is transported to a crusher for primary crushing, then introduced into a wet mill and ground to a particle size of less than 50 microns, and then wet milled by adding water and additives Slurry. The prepared coal water slurry is stored in the coal water slurry storage tank, and the addition amount of the coal water slurry is controlled by the coal water slurry weighing instrument. The coal-water slurry is delivered to the micro-nano separation equipment at a pumping pressure of 0.3Mpa through the coal-water slurry feed pump and the coal-water slurry delivery pipeline.

[0043] The separation principle of the micro-nano separation equipment is based on the difference of particle surface properties and the principle of particle interference and sedimentation in th...

Embodiment 2

[0046] This example illustrates that the low-sulfur and low-ash ultrafine solid carbonaceous material particles M obtained in Example 1 are blended in various proportions into various liquid fuels and gaseous fuels F (the blending ratio is calculated according to the M / F mass ratio) After the application effect. Wherein, when blended into liquid fuel, the dispersant used is terpineol oil, and its dosage is 2.5 wt% of the weight of the low-sulfur, low-ash ultrafine solid carbonaceous material particles. Then, according to the national standard method, the indicators before and after blending were measured, and the specific data are shown in Table 1.

[0050] Note 1: The M / F value of coal-water slurry refers to the mass ratio of particles M to conventional coal powder for slurry preparation.

[0051] Among them, for liquid fuel, not only the energy density is improved, but also the cost of liquid fuel per unit volume or unit calorific v...

Embodiment 3

[0056] This embodiment illustrates the application effect after the low-sulfur and low-ash ultrafine solid carbonaceous material particles M obtained in Example 1 are blended into liquid fuel F (a certain DMB marine fuel oil) (the blending ratio is 30%, according to M / F mass ratio calculation). Granule M has not been treated by wet method or pyrolysis desulfurization, and the sulfur content is 0.2%. The dispersant used is pine alcohol oil, and its consumption is 3wt% of the weight of the ultrafine solid carbonaceous material particles with low sulfur and low ash. The energy density changed from 33558kJ / L before blending to 35417kJ / L after blending; the viscosity of liquid fuel changed from 7.0mm before blending 2 / s becomes 7.8mm after blending 2 / s, slightly up. The unit calorific value liquid fuel cost after blending is about 24% lower than before blending.

[0057] The sulfur content of the DMB marine fuel oil is 0.5%, and the sulfur content of the liquid fuel is reduce...

Abstract

The invention discloses a method of increasing energy density of liquid fuel or gaseous fuel. The method is characterized in that low-sulfur and low-ash superfine solid carbon material particles with an ash content of less than 3wt%, a total sulfur content of less than 0.6wt% and an average particle size of less than 500 micrometers are doped into the liquid fuel or the gaseous fuel. The low-sulfur and low-ash superfine solid carbon material particles are obtained by separating low-ash superfine solid carbon material particles from a carbon material source via a micro mineral separation technology and performing desulfuration via a desulfuration technology as appropriate. The method can increase the energy density of the liquid fuel in unit volume by 1.4 times and a calorific value of the gaseous fuel in the unit volume by 4 times maximally.

Description

technical field [0001] The invention belongs to the field of fuel additives, in particular to a method for increasing the energy density of liquid fuel or gaseous fuel. Background technique [0002] Liquid fuel and gaseous fuel are the main sources 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 fuel density of these fuels in order to increase heat 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 improve liquid fuels and gaseous fuels include using fuels with higher density or higher unit calorific value, but the improvement of fuel density and unit calorific va...
