Problems solved by technology

[0006] The technical problem mainly solved by the present invention is aimed at the high viscosity of the fuel oil currently used in boiler combustion, so the surface tension is large and the atomization is poor, resulting in large sprayed oil droplets during the application process, resulting in incomplete combustion, which will increase Coking and carbon deposits make the operation efficiency of the combustion furnace or engine cylinder low. Compared with the defect of mineral oil, the currently developed biological liquid fuel oil has a lower calorific value, and a method for the preparation of low-viscosity carbon-deposit-reduced fuel oil is provided.

example 1

[0025] In parts by weight, 70 parts of biogas slurry, 20 parts of shell powder, 4 parts of chitosanase, 5 parts of Nile red, and 5 parts of chlorella were added to the plastic tank, and they were placed in a place with sufficient light and air circulation for cultivation. During the period, after the daily light was over, the culture liquid in the plastic tank was inspected with ultraviolet light. After the surface of the culture liquid in the plastic tank was found to be completely covered with red, the culture was terminated, and the surface chlorella was salvaged, and put into a high-speed centrifuge for dehydration. Rotate at 4000r / min, centrifuge for 12min, remove the supernatant to obtain the lower chlorella sediment, put the chlorella sediment into an oven, heat up to 80°C, and dry for 10 hours to obtain the dried chlorella sediment; Place the dried chlorella sediment in an ultrasonic breaker to break the wall, control the ultrasonic frequency to 40kHz, and the ultrasoni...

[0029] In parts by weight, add 80 parts of biogas slurry, 25 parts of shell powder, 5 parts of chitosanase, 10 parts of Nile red, and 10 parts of chlorella to the plastic tank, and place it in a place with sufficient light and air circulation for cultivation. During the period, after the daily light was over, the culture liquid in the plastic tank was inspected with ultraviolet light. After the surface of the culture liquid in the plastic tank was found to be completely covered with red, the culture was terminated, and the surface chlorella was salvaged, and put into a high-speed centrifuge for dehydration. Rotate at 4300r / min, centrifuge for 15 minutes, remove the supernatant to obtain the lower layer of chlorella sediment, put the chlorella sediment into an oven, heat up to 90°C, and dry for 12 hours to obtain the dried chlorella sediment; Place the dried chlorella sediment in an ultrasonic breaker to break the wall, control the ultrasonic frequency to 45kHz, and the ultrason...

Abstract

The invention discloses a preparation method of low-viscosity carbon deposit-reducing fuel oil, and belongs to the technical field of new energy production. In the method, high-calorific value liquidbio-fuel oil is produced from chlorella, which has an obvious single-cell protein nucleus; with biogas slurry, shell powder and the like wastes being culture substrate, atomized dispersion liquid is prepared from ethanol trimer, ethylene glycol monobutyl ether, octadecyl sulfobetaine and the like, wherein the octadecyl sulfobetaine has certain cleaning performance on tar; V2O5, isobutanol and benzyl alcohol are used as raw materials and are subjected to a heating reaction in a phosphoric acid solution; methanol and isopropanol serve as a dispersion liquid; before combustion, magnesium powder can be subjected to oxidization complexing with sodium polyphosphate and triethanolamine through preheating, thus forming an oleophobic protective layer for reducing deposition of a residual carbon layer during the combustion of the fuel oil, magnesium being reduced into the magnesium powder; according to such circulating reaction with the residual carbon layer, the deposition of the residual carbon layer can be reduced. The method has extensive application prospect.

Description

technical field [0001] The invention discloses a method for preparing low-viscosity carbon-deposition-reduced fuel oil, which belongs to the technical field of new energy preparation. Background technique [0002] Fuel oil is also called heavy oil and residual oil. It is a dark brown viscous flammable liquid with moderate viscosity, good fuel performance and high calorific value. The properties of fuel oil mainly depend on the nature of crude oil and processing methods, and the main specifications that determine the quality of fuel oil include viscosity, sulfur content, pour point, etc. Fuel oil for power plants also has regulations on vanadium and sodium content. [0003] Fuel oil is mainly made of petroleum cracking residue and straight-run residue, which is characterized by high viscosity and contains many non-hydrocarbon compounds, colloids, and asphaltenes. Its components are mainly hydrocarbons, and also contain some sulfur and trace amounts of inorganic compounds. I...
