Description

A kind of hydrogen gas and methanol fuel and preparation method thereof for M100

Technical field

The present invention relates to technical field of fuel preparation, in particular to a kind of for the hydrogen gas and methanol fuel of M100 and its preparation Method.

Background technique

With manufacturing development, mechanically the demand of burning oil such as gasoline is gradually increased, still, existing vapour Oil can generate a large amount of pollution gas and graininess pollutant after combustion, seriously affect the quality of environment.Therefore, respectively Pedestrian scholar actively studies Environment-friendlyfuel fuel, to reduce burning exhaust gas.But accomplishing to reduce burning dirt in existing technology It while contaminating object discharge, decreases the calorific value of fuel also, so that mechanical output power reduces, influences making for user If things go on like this mechanical performance can also be adversely affected with impression.

It is well known that hydrogen is a kind of substance of calorific value high (heat that 1g Hydrogen Energy discharges 142 kJ (kilojoule)s), liquid condition It is 3 times of gasoline calorific value, combustion product is water, it without lime-ash and exhaust gas, does not pollute the environment, and flammability is good, ignition point Low, burning point is high and burning velocity is fast, and the calorific value of methanol is low, and power performance is low.Therefore, if hydrogen and methanol can be blended in Together, using the oxygen interreaction in liquid hydrogen and methanol, and a certain amount of additive is added, it is applied in automobile and is fired It burns, is then not only avoided that the generation of burning pollutant, and combustion heat value can be improved, provided for burns gasoline machinery bigger Power.

Summary of the invention

In order to solve the above technical problems, technical solution provided by the invention are as follows: a kind of hydrogen gas and methanol fuel for M100 And preparation method thereof, take hydrogen and 80~85 parts of methanol, 20~25 parts of additive, at normal temperatures and pressures by a certain amount of hydrogen first It is mixed with methanol, and additive is added, can be obtained hydrogen gas and methanol fuel.

Preferably, the additive includes following component: 3~3.5 parts of dimethyl carbonate, 2~2.5 parts of isopropanol, and MTEB 0.85~0.99 part, 1~1.2 part of different monooctyl ester, 0.6~0.9 part of acetone, 1.8~2.2 parts of first contracting an aromatic plant metioned in ancient books, 0.2~0.33 part of PVP, 1.5~1.9 parts of n-butanol, 1.5~1.9 parts of isobutanol, 0.6~0.9 part of cyclohexylamine, 3.9~4.1 parts of aromatic hydrocarbons and ethyl acetate 1.5~1.8 parts.

Preferably, when liquefying to hydrogen, high-quality hydrogen is selected, and a certain amount of methanol is squeezed into reaction kettle processed In；Reaction kettle lower part is equipped with ventilation interface, and close energy conversion pin hole processed is arranged at bottom in reaction kettle, first by hydrogen to be greater than 2.1MPa Pressure by interface be sent into bottom board, and after through energy conversion pin hole be diffused into methanol solution, then use circulating pump Mixing liquid in kettle is pumped into static mixer, returns again to reaction kettle, so recycle 20~30 minutes, realize hydrogen by gaseous state to The conversion of liquid.

Preferably, the mass fraction of the hydrogen gas and methanol and additive is respectively as follows: the molecule content of hydrogen in methyl alcohol 200-300PPM, 80 parts of methanol, 3.5 parts of dimethyl carbonate, 2 parts of isopropanol, 0.9 part of MTEB, 1.2 parts of different monooctyl ester, acetone 0.8 Part, 2 parts of first contracting an aromatic plant metioned in ancient books, 0.2 part of PVP, 1.5 parts of n-butanol, 1.5 parts of isobutanol, 0.8 part of cyclohexylamine, 4 parts of aromatic hydrocarbons and ethyl acetate 1.6 parts, after dissolution, addition can be obtained M100 hydrogen gas and methanol fuel in proportion.

After the above ingredient and preparation method, the present invention has the advantage that

(1) by the way that a certain amount of liquid hydrogen to be incorporated into methanol, burning is then mixed with gasoline, hydrogen is just and in methanol Oxygen full combustion, it is three times of gasoline that the combustion heat value of hydrogen, which is 142MJ/Kg, and the product after burning is water, will not be produced Raw lime-ash and exhaust gas, and the consumption of methanol is increased, it is not only environmentally friendly, and calorific value is high, and utilizability is strong；

(2) in order to realize that the stabilization of hydrogen gas and methanol is smoothly used, prevent from causing during burning under machine power will, Gasoline meets the problems such as water stratification, corrosion metal, swollen rubber, joined various additives, realizes of the invention steady in a long-term Using.

Specific embodiment

The present invention is described in further detail below.

In the present invention, the effect difference for the additive being related to is as follows:

Dimethyl carbonate: anti-corrosion improves calorific value, improves flammability；Isopropanol: increase rate alkane value, it is anti-corrosion, antifreeze and de- Water；MTEB (methyl tertiary butyl ether(MTBE)): hydrotropy, cold-starting improve saturated vapour pressure, and increase rate alkane value increases power, the row of reduction High-volume；Different monooctyl ester: anti-corrosion improves calorific value, improves flammability；Acetone: hydrotropy, anti-layering, anti-vapour lock；First contracting an aromatic plant metioned in ancient books: cold-starting, Improve flammability；PVP (polyvinylpyrrolidone): good miscible agent can be such that preparation thickens, and hinder releasing for hydrogen gas and methanol vaporization It puts；N-butanol: cosolvent；Isobutanol: cosolvent；Cyclohexylamine: corrosion inhibiter；Aromatic hydrocarbons: octane number is improved；Ethyl acetate: it improves pungent Alkane value.

Mixing burning due to hydrogen gas and methanol will appear a series of problems, therefore need to be added in the mixture of hydrogen and methanol Blender, including detergent-dispersant additive, antioxidant, corrosion inhibiter, antiwear additive, waterproofing agent, antifreezing agent, uprising dose, solvent resistant, stabilization Agent, catalyst, combustion adjuvant and cold start-up additive.

During with the present invention, it is necessary to meet the following conditions: (1) must satisfy the liquid fuel of various engines General character requirement to quality, i.e., vapo(u)rability appropriate, good flammability, the safety of height, good low temperature properties are good The requirement of cleanliness, non-corrosive, the economy of fuel, energy conservation and environmental protection；(2) present invention being fabricated to must have compatibility Can, it can be used in mixed way with gasoline in the market with arbitrary proportion.
