Description

Technical Field

[0001] This invention relates to the field of fuel preparation technology, and in particular to a novel mixed water-based fuel and its processing method. Background Technology

[0002] With the escalating global energy crisis and increasingly stringent environmental protection requirements, traditional fossil fuels and existing water-based fuels struggle to simultaneously meet the multiple demands for fuel efficiency, storage stability, and environmentally friendly combustion. They fail to satisfy the high standards of clean energy usage required in various scenarios, including industrial production and residential combustion. Therefore, developing a novel hybrid water-based fuel that boasts high fuel efficiency, stable quality, excellent emission reduction effects, and suitability for large-scale use in multiple scenarios, along with a simple and controllable preparation method, has become a pressing technical challenge in this field. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a new type of mixed water-based fuel. This fuel achieves high fuel saving rate, stable quality, emission reduction and environmental protection through the scientific ratio and precise selection of various functional components, and is suitable for use in multiple scenarios.

[0004] Another objective of this invention is to provide a processing method for the above-mentioned novel mixed water-based fuel. This method is simple, easy to implement, and controllable in operation. It can achieve uniform fusion of the components, ensure stable and controllable fuel product quality, and is suitable for industrial and large-scale promotion and production.

Heavy aromatics have a high calorific value, making them suitable for industrial applications requiring high calorific values. The core functions of heavy aromatics are: providing core combustion calorific value for fuels, ensuring basic fuel combustion performance, exhibiting excellent compatibility with water and base oils, showing no stratification after mixing, and having a higher calorific value than conventional light aromatics.

[0006] The base oil used is one or more of the following: No. 46 fully synthetic base oil, No. 68 mineral base oil, and hydrotreated base oil. No. 46 fully synthetic base oil is suitable for precision combustion equipment; No. 68 mineral base oil is more cost-effective and suitable for low-cost, large-scale industrial production; hydrotreated base oil has high cleanliness and is suitable for scenarios with high requirements for combustion cleanliness. The core functions of the base oil are: to provide basic lubricity and auxiliary calorific value to the fuel, improve the stability of fuel combustion, and reduce internal wear of the combustion equipment.

[0007] The catalyst employs one or more of the following: nano-cerium dioxide, nano-titanium dioxide, and ZSM-5 molecular sieve catalyst. Nano-cerium dioxide is a general-purpose catalyst suitable for various conventional applications; nano-titanium dioxide can specifically reduce nitrogen oxide emissions, suitable for applications requiring low nitrogen oxide emissions; and ZSM-5 molecular sieve catalyst has high catalytic efficiency, suitable for applications requiring high thermal efficiency. The core functions of the catalyst are: lowering the ignition point of the fuel, promoting complete combustion, improving overall combustion efficiency, and reducing the emission of unburned materials.

[0008] The combustion improver is one or more of tert-butyl peroxide, di-tert-butyl peroxide, and isooctyl nitrate. Tert-butyl peroxide is a general-purpose combustion improver, suitable for various conventional combustion equipment; di-tert-butyl peroxide has good high-temperature resistance, suitable for high-temperature combustion scenarios; isooctyl nitrate has good compatibility with diesel fuels, suitable for diesel combustion equipment. The core function of the combustion improver is: it has strong oxidizing properties, releases active oxygen during combustion, accelerates the fuel combustion reaction, improves fuel burnout rate, and further improves fuel-saving performance.

Polyisobutylene succinimide is a general-purpose dispersant suitable for various component ratio systems; polymethacrylate has excellent dispersion effect on the aqueous phase and is suitable for fuel systems with a high proportion of aqueous phase; sorbitan monooleate is an environmentally friendly dispersant suitable for civilian combustion scenarios. The core function of the dispersant is to effectively solve the miscibility problem between water and oil phases, reduce interfacial tension, ensure uniform dispersion of each component in the fuel system, prevent fuel stratification and precipitation, and ensure long-term storage stability of the fuel.

[0010] The environmentally friendly cleaning agent uses one or more of the following: polyetheramine (TPEA), polyisobutyleneamine (PIBA), and salicylates.

The core function of the environmentally friendly cleaning agent is to effectively remove carbon deposits inside combustion equipment while reducing the emission of harmful gases such as nitrogen oxides and hydrocarbons during fuel combustion, thus combining the dual functions of equipment cleaning and environmental emission reduction.

[0011] Preferably, the catalyst is composed of nano-cerium dioxide and nano-titanium dioxide in a mass ratio of 2:1.

[0012] This invention also discloses a processing method for the above-mentioned novel mixed water-based fuel, comprising the following steps: a. Preparation and initial setting: According to the weight percentage ratio, take 30% of the total weight of the raw materials as pure water and pour it into a container for later use; b. First stage mixing: Add 25% of the total weight of heavy aromatics and 20% of the base oil to a container filled with pure water. Turn on the stirring equipment and stir at a rate of 300-500 r / min for 5-8 minutes to allow the heavy aromatics, base oil and water to be fully and initially mixed. c. Second stage mixing: Continue to slowly inject catalyst accounting for 10% of the total weight of raw materials into the container, maintain a stirring rate of 300-500 r / min, and continue stirring for 5-8 min to ensure that the catalyst is fully and evenly dispersed in the mixture; d. Heating and third-stage mixing: The container containing the above mixture is heated to a certain temperature. During the heating process, the mixture is continuously stirred at a rate of 200-300 r / min to prevent local overheating. The temperature of the mixture is monitored in real time with a thermometer. When the temperature reaches 40℃±5℃, the heating is stopped. Then, a dispersant of 10% of the total weight of the raw materials is injected into the container, and the mixture is stirred at a rate of 300-500 r / min for 5-8 minutes. e. Natural cooling: Place the container containing the above mixture in a room temperature environment and allow it to cool naturally to room temperature (25℃±2℃) to avoid high temperature damaging the effective components of the subsequently added components; f. Final mixing: Add 2% of the total weight of the combustion improver and 3% of the environmentally friendly detergent to the mixture after natural cooling. Stir thoroughly for 5 to 8 minutes at a stirring rate of 300 to 500 r / min until all components are completely mixed to obtain the new type of mixed water-based fuel product.

[0013] Furthermore, in step d, the container containing the mixture is heated by a water bath or an oil bath. This heating method is gentle, controllable, and safer and more reliable.

Through staged addition, precise temperature control, and constant speed and time stirring, the uniform fusion of each component is achieved, ensuring the consistency of product quality. It is suitable for large-scale, industrialized, and multi-scenario production.

[0017] 4.
