Embodiment 1-4

[0096] The test method for the stability test of granular nano-fuel catalytic additives is as follows:

[0097] While stirring at 20 °C and 60 rpm, the nano-fuel catalytic additive was prepared, and the dissolution rate until the lignin was completely dissolved in the A-grade heavy oil was evaluated by measuring the number of seconds. The stability of the solution obtained after standing at room temperature for one week was evaluated.

[0098] "Very good" means completely dissolved,

[0099] "Good" means almost dissolved,

[0100] "Qualified" means that a small amount of insoluble matter can be observed,

[0101] "Not good" means that very much insoluble material was observed.

[0102] The test results are shown in the table below

[0103]

[0104] The nano-fuel catalytic additive components of the above-mentioned Examples 1-4 were extruded into granules through a screw. Add 1g of nano fuel catalytic additive (ie 0.5%) to 200g of diesel. Test the TG carbon slag burnin...

Embodiment 5-10

[0106] The test method for the stability test of liquid nano-fuel catalytic additives is as follows:

[0107] While stirring at 20°C and 60rpm, the nano-fuel catalytic additive was prepared by the composition shown in the table below, and the dissolution rate until the lignin was completely dissolved in the A-grade heavy oil was evaluated by measuring the number of seconds. The stability of the solution obtained after standing at room temperature for one week was evaluated.

[0108] "Very good" means completely dissolved,

[0109] "Good" means almost dissolved,

[0110] "Qualified" means that a small amount of insoluble matter can be observed,

[0111] "Not good" means that very much insoluble material was observed.

[0112] The test results are shown in the table below.

[0113]

[0114]

[0115] After the above components are uniformly dispersed in the dispersant, 0.2g of nano fuel catalytic additive (ie 0.1%) is added to 200g of diesel. Test the TG carbon slag burnin...

Abstract

The invention relates to a nanometer fuel oil catalytic additive which has good dispersity and lubricity, can be used for assisting the fuel oil to combust fully and is environmentally-friendly. The granular nanometer fuel oil catalytic additive comprises the following components in parts by weight: 1-10% of nanometer catalyst, 90-99% of xylogen and 0.1-1% of water. A preparation method of the nanometer fuel oil catalytic additive comprises the following steps of: mixing the nanometer catalyst, the soluble xylogen and water in parts by weight, and prilling through a screw extruder. A liquid nanometer fuel oil catalytic additive comprises 100 parts by weight of solvent, 0.5-1 part of nanometer catalyst, and 5-10 parts of xylogen. A preparation method of the liquid state nanometer fuel oil catalytic additive comprises the following steps of: mixing the nanometer catalyst, the soluble xylogen, the solvent, polyethylene glycol and other addition agents in parts by weight, and uniformly stirring and mixing in a speed of 60 rpm (revolutions per minute) at 20 DEG C till the liquid state nanometer fuel oil catalytic additive is in a stable state.

Description

technical field [0001] The invention relates to a fuel catalytic additive, in particular to a nano fuel catalytic additive. [0002] Background technique [0003] With the increase of the number of domestic locomotives in recent years, the consumption of fuel oil such as gasoline and diesel is increasing day by day, and a large amount of imported oil is needed to meet the demand of the domestic market. The demand for the development of fuel-saving additives and alternative oil products is becoming more and more urgent. Existing gasoline (or diesel) has few branched chain alkanes and low octane number (cetane number), which is prone to knocking phenomenon in which fuel and air are mixed and spontaneously ignites, resulting in insufficient fuel combustion, producing carbon monoxide, nitrogen oxide and unburned gas. Harmful substances such as hydrocarbons and black smoke affect the ecological environment and human health; solid substances such as coke produced by incomplete co...
