Benefits of technology

[0031]As a result, the method of the present invention makes the most of the valuable energy resources and cheap materials, changes waste into values, improves oil quality, and converts emulsified fuel oil of low heating value, high viscosity, high sulfur content, water contained, and high condensation point into the emulsified fuel oil with the advantages of high heating value, low viscosity, good liquidity, low sulfur content, and low condensation point.
[0032]The emulsified fuel oil of the present invention can satisfy the technical standard of 0# light diesel oil, and thus can be used for high speed diesel engine trucks and fuel boiler, and can be burnt completely without discharging dark smoke, and thereby, reaches the standard of environmental protection and energy saving. The emulsified fuel oil of the present invention can be stored for a long time without layering and contains particles with a particle size of less than 5 μm, and has a good liquidity under the temperature of between −20° C. and −40° C., and thus can be stored and transported conveniently.

Problems solved by technology

However, there are still many deficiencies to be improved, and thus one cannot promote the emulsification technology more widely.
The main deficiencies of the emulsified fuel oil are: 1) the storage is not stable, oil and water separation phenomena will happen in several months after emulsification, even only after several days; 2) the heating value reduces when burning, the heating value of a normal emulsification oil reduces to about 6000-7000 kcal / kg; 3) the sulfur content is not decreased significantly, especially for the oil emulsified from the heavy oil imported from middle east regions, the sulfur content is still more than 2%, resulting in the discharge of harmful gases such as SO2, NOx, soot, and so on, leading to serious environmental pollution; 4) the condensation point is high, the emulsification oil must be stored in an environment with a certain temperature; some emulsification oil can only be emulsified and then burned directly, and is unlike light diesel oil that can be stored in oil storage tank and transported by pipelines; 5) the quality of emulsification oil is not improved largely, and thus can not be used for high speed diesel engines (>2200 rpm), agricultural transportation vehicles, and truck power units; 6) the ash content is high, the residual carbon and rare elements such as V and Mo are high, resulting in damage of the machines; and 7) the viscosity is high and a lot of colloids exist, resulting in jam of the nozzle.
However, the high energy liquid fuel cannot solve the above problems.
For example, the storage stability is poor, the oil will thicken after storing for only 6 months; the sulfur content is certainly improved, but it still cannot meet the relevant national and international standards; though the condensation point is decreased, it is still not satisfying; the quality of the emulsification oil is increased and can meet the standard of 1# marine fuel oil, but it cannot satisfy the requirement of 0# light diesel fuel oil and thus cannot be used for high-speed diesel engine and tractor trucks; since the oil thickens after a certain time of storage, it cannot be transported by pipelines; and the raw materials to be used are also limited.
