Abstract

The present invention relates to one kind of biodiesel oil prepared with vegetable oil, methanol, ethanol, kerosene, 0# diesel oil and additive. The vegetable oil may be palm oil, rape seed oil, soybean oil, etc. The process of preparing the biodiesel oil includes the following steps: adding vegetable oil in 20 wt%, methanol in 25 wt% and 0# diesel oil in 40 wt% into the first reactor, and catalytically reacting while heating and stirring to obtain transparent resultant liquid; adding kerosene in 5 wt%, ethanol in 5 wt% and additive in 5 wt% into the second reactor successively, and reacting under the action of Ti catalyst and through stirring; cooling the resultant liquid from the first reactor quickly in a cooling reactor and feeding the cooled resultant liquid to a third reactor; and adding the resultant liquid from the second reactor to the third reactor for catalytically hydrogenating reaction until obtaining transparent product. The biodiesel oil is environment friendly.

Description

Environment-protective biodiesel and preparation method thereof

Technical field

The present invention relates to biofuel, be specifically related to a kind of biofuel of having utilized vegetables oil and No. 0 diesel oil participation preparation, be widely used in aspects such as diesel car, locomotive, steamer, generating, mining machinery.Belong to International Classification of Patents C10G " preparation of liquid hydrocarbon mixture " technical field.

Background technology

The present diesel oil that uses belongs to non-renewable resource as the petrifaction diesel of refining of petroleum.In production, processing and the use of this class diesel oil, balance of nature is existed immeasurable recessive the threat.Therefore, seeking surrogate in natural round-robin renewable resources becomes inevitable.There is some evidence that the oil production in the world is near historical climax.Because the scarcity of oil, industrial country will enter the lag phase of economic depression even Economic development.From the situation of China, China became the second-biggest-in-the-world oil consuming countries after the U.S. since 2003, and a year crude oil import amount has increased by 31%.In the face of this situation, scientific research institution had once carried out the research of extracting diesel oil from coal tar, but because coal chemistry is also very serious to the pollution of environment, finally can only look for its way in addition.At present domestic also have research and inquire in the bio-synthetic diesel field, but manufacturing cost height often, the equipment configuration complexity, impracticable.And the diesel oil that aspects such as the diesel car of present China, locomotive, steamer, generating, mining machinery are used is all based on mineral oil.Because the exhaust emissions situation of mineral oil has caused severe contamination to ecotope, has had a strong impact on people's life, environment and healthy.

Summary of the invention

The purpose of this invention is to provide a kind of environment-protective biodiesel that comprises the vegetables oil raw material and preparation method thereof.

The objective of the invention is to be achieved through the following technical solutions.

A kind of environment-protective biodiesel and preparation method thereof, its composition comprise vegetables oil, methyl alcohol, ethanol, kerosene, No. 0 diesel oil and additive etc.

The weight percentage of described each composition is vegetables oil 20%, methyl alcohol 25%, ethanol 5%, 5%, No. 0 diesel oil 40% of kerosene, additive 5%.

More than the weight percentage of each composition also can be: vegetables oil 25%, methyl alcohol 25%, ethanol 5%, 5%, No. 0 diesel oil 35% of kerosene, additive 5%.

More than each composition weight percentage be: vegetables oil 30%, methyl alcohol 20%, ethanol 5%, 5%, No. 0 diesel oil 35% of kerosene, additive 5%.

The preparation method of environment-protective biodiesel is as follows:

1) with 20% vegetables oil, in the titanium catalytic reaction kettle---in No. 1 still, heat, stir catalysis to 50 ℃, add 25% methyl alcohol then, the stirring that continues to heat adds 40% No. 0 diesel oil, the stirring of heating again, be warming up to 60-70 ℃, produce aggravation titanium catalyzed reaction in the still, transparent to synthetic liquid;

2) with 5% ethanol, 5% kerosene, 5% additive join another one titanium catalytic reaction kettle sequentially---and carry out the titanium catalyzed reaction in No. 2 stills, stirred 5 minutes;

3) the synthetic liquid in No. 1 still is delivered in the cooling reactor, is lowered the temperature 10-20 ℃ rapidly, deliver to strontium catalytic hydrogenation reaction still again---in No. 3 stills, stir catalysis, synthetic liquid in No. 2 stills is also delivered in No. 3 stills, is carried out catalytic hydrogenation reaction, be stirred to dissolve each other, till the homogeneous transparent.

Described vegetables oil can utilize plam oil, rapeseed oil, levant cotton oil, Cortex jatrophae oil, soybean wet goods various plants oil.

The preparation of described additive, be with pure metallic titanium, strontium carry out laser pulverize the nanoscale powder obtain synthetic in proportion after, add Nitromethane 99Min., n-propyl alcohol, trichloromethane, synthesize additive; Described ratio is ti powder 10 grams, strontium powder 5 grams, Nitromethane 99Min. 60 grams, trichloromethane 20 grams, n-propyl alcohol 5 grams.

The invention provides a kind of vegetables oil, methyl alcohol, ethanol of renewable resources of utilizing and be basic material, make vegetables oil become the environment-protective biodiesel of modification, have the basic function of mineral diesel through titanium, strontium catalysis.Prescription of the present invention is unique, has possessed the basic function of mineral diesel fully, also can make the objectionable impurities of various diesel engines exhaust emissions reduce more than 90% simultaneously.Promoted the use of on a large scale, can not destroyed the eubiosis, can not caused pollution, can not influenced people's life and healthy air ambient, and renewable, never exhausted.The present invention does not contain the aromatic series alkane that environment is polluted, thereby the infringement of human body is lower than mineral diesel, can significantly reduce the pollution to environment.

Embodiment

Embodiment 1

Vegetables oil 20%, methyl alcohol 25%, ethanol 5%, 5%, No. 0 diesel oil 40% of kerosene, additive 5%.

Embodiment 2

Vegetables oil 25%, methyl alcohol 25%, ethanol 5%, 5%, No. 0 diesel oil 35% of kerosene, additive 5%.
