Abstract

The invention discloses an energy-saving low-carbon diesel oil core agent composed of a cetane number improver, an antioxidant, a cleaning dispersant, a flow improver, a combustion improver, an antifreezing agent, a flavor removing agent, a carbon reduction agent and the like. The core agent is mainly used for automotive methanol diesel oil, overcomes cold startability, improves combustion chamber carbon deposit, makes an engine clean, reduces engine wear caused by methanol combustion, reduces emissions of combustion waste gas, effectively inhibits metal corrosion and rubber swelling, strengthens and improves large-proportion methanol, catalyzes the combustion effect, and opens up a new method of a large-proportion methanol combustion technology for application of methanol diesel oil, microemulsion alcohol diesel oil, methanol biodiesel oil and alcohol-based fuels.

Description

A kind of energy-saving low-carbon diesel oil core-agent

Technical field

The present invention relates to a kind of energy-saving low-carbon diesel oil core-agent, particularly a kind of technology of core-agent.

Technical background

Methyl alcohol because of it, there is cleaning, high heating value, high-level efficiency and the feature such as easily to obtain by the potential first-selected liquid fuel of countries in the world diesel oil as an alternative.Country is more had to it can be used as a kind of fuel liquid for automobile of reality to use.Domestic methyl alcohol is had more example as substitute metirials of diesel oil.Then be among exploration as substitute metirials of diesel oil.Methyl alcohol is used as the subject matter that vehicular engine fuel exists: one is that the dynamic performance of methanol fuel is lower than diesel oil; Two is that cetane value is low, only has 2-3, and when diesel engine compression is started its cetane value can not to be less than 453 the 3rd be that the nonmetal parts of methyl alcohol to engine system has swelling corrosive nature, and potential corrosion problem is existed to metalwork.4th is that the viscous modulus of methyl alcohol is little, and thus it has certain souring to engine system.This four problems affects the major obstacle that methyl alcohol is used as diesel-fuel at present.

Summary of the invention

The present invention is directed to the methanol fuel burning existed in prior art not enough, provide a kind of use for diesel engine methanol fuel special core-agent.This special core-agent can to make in use for diesel engine methanol fuel methanol content up to more than 90%, and has good dynamic performance and low-corrosiveness.

Use for diesel engine methanol fuel core of the present invention agent, solve above-mentioned technical problem adopt a kind of scheme of energy-saving low-carbon diesel oil core-agent to be made up of following weight percent: 1. cetane number improver 1-5%, 2. antioxidant 1-3%, 3. detergent-dispersant additive 1-3%, 4. FLOW IMPROVERS 1-5%, 5. ignition dope 1-3%, 6. frostproofer 1-596,7. dispel taste agent 1-3%, 8. carbon reduction agent 1-5%.

Described a kind of energy-saving low-carbon diesel oil core-agent, wherein 1. cetane number improver improving agent is by isoamyl nitrate, isooctyl ester nitrate, one or both mixture wherein; 2. antioxidant is by hydroxy diphenylamine, the mixture of 2.6-ditertbutylparacresol; 3. detergent-dispersant additive is by allyl butyrate imide, polyisobutenyl succinimide wherein one or both; 4. FLOW IMPROVERS be by vinyl acetate between to for plastic acid and fumaric acid resin copolymer, EVA, ethylene-acrylic acid, wherein one or both; 5. ignition dope is by sulfonated petro-leum, alkyl phenate, and salicylate is a kind of or three kinds of multipolymers wherein; 6. frostproofer is by ethylene glycol ethyl ether, diethylene glycol ether, ethylene glycol monomethyl ether, diethylene glycol dimethyl ether, ethylene glycol wherein one or both; 7. taste agent of dispelling is by Glacial acetic acid, isobutyl acetate, 2.2-dimethylbutane, ethyl acetate, wherein one or both; 8. carbon reduction agent is by dme, methyl lactate, ammonium naphthenate wherein one or both.

Each compositions in weight percentage example joins in reactor item by item above, vacuumizes, and temperature controls at 50-60 DEG C, stir 1-1.5 hour, to be achieved transparent till, a kind of energy-saving low-carbon diesel oil core-agent can be become.

Embodiment

Raw material in following instance is all by weight percentage:

Embodiment 1.

The raw material of this example consists of: cetane number improver is 3%, antioxidant 3%, detergent-dispersant additive 3%, FLOW IMPROVERS 3%, ignition dope 2%, frostproofer 3%, dispel taste agent 2%, carbon reduction agent 3%, squeezes in reactor item by item by above-mentioned raw materials, vacuumize, control temperature 50-60 degree, till low rate mixing 1-1.5 hour makes its complete Homogeneous phase mixing transparent, make to react completely, after cool to room temperature, barrelling seals, and namely obtained this implements a kind of energy-saving low-carbon diesel oil core-agent.

Embodiment 2.
