Abstract

A biological diesel oil is prepared from rape oil, turpentine, paraffin and additive of ferrocene. Its preparing process includes adding abovesaid materials into mixer for mixing 10-50 min. at normal temperature and normal pressure, stewing mixer for one hour and obtaining product through filtering.

Description

A kind of biofuel

Technical field

The present invention relates to a kind of biofuel, refer in particular to a kind of particularly biodiesel for automobile of rapeseed oil production of vegetables oil that utilizes.

Background technology

The product that existing commercially available diesel oil is refining of petroleum basically is a petrifaction diesel, belong to Nonrenewable resources, in its production, processing, use balance of nature is also had the recessiveness that has explosive power and threaten, therefore seeking surrogate in natural round-robin renewable resources becomes inevitable.There are indications, world oil production is near the historical high peak, if the energy reserves of industrial country is with annual 2% speed decline, and sun power and wind-power electricity generation can only satisfy the demands 1%, industrial country's stage that must enter economic depression even develop into economic stagnation then, and also can grow in intensity for the energy reserves less and less and the contention of unminding the base.China became the second-biggest-in-the-world oil consuming countries after the U.S. since 2003, a year imported crude oil has increased by 31%, and in the face of above-mentioned fierce day by day oil competition, the cost that China pays also increases day by day; Therefore be to have carried out from coal tar to produce the research of diesel oil and obtained phasic results as one of counte-rplan, but also be fossil oil in view of coal is the same with oil, non-renewable and environmental pollution is serious, finally still can only keep away its in addition on the way.In recent years, go to develop the exploitation problem that the green energy resource reproducible, that environmental pollution is little becomes the countries in the world researchist from the plant biological circle, countries such as the U.S., Germany, France, Italy, Sweden, Australia, Czech have set about carrying out the technical research work of biofuel, obtained initial success, its preparation method is that the animal and plant grease is made fatty acid methyl ester and vegetables oil methyl esters through chemical process, again through wash dry after and get; At present relevant report at home concentrates on Hainan Province and gets biofuel for raw material through hydrolysis, alcoholysis, esterification with waste cooking oil, oil expression waste residue and forest oil fruit (the little seeds of a tung oil tree, Chinese pistache), and it is raw material that Fujian Province uses " rubbish oil ", also gets through alcoholysis, esterification.The shortcoming of above-mentioned chemical synthesis is, complex process, and alcohol must be excessive in the processing, thereby also must supporting corresponding pure retrieving arrangement, the energy consumption height, the cost height, the product yield is low; At high temperature perishable, the esterification products of unsaturated fatty acids is difficult to reclaim, the waste lye discharging is arranged in the production process in the fat.In order to solve the shortcoming of chemosynthesis, also once attempted to adopt the biological enzyme method, be about to transesterification and undertaken by lipase, but conversion of methanol is low, generally has only 40～60%, and methyl alcohol has certain toxicity to lipase, shortened the work-ing life of enzyme, cause the cost height.Domestic research in field of biodiesel oil is progressively in-depth, but because the defective of chemical synthesis, existing researchist is more prone to adopt the simple and easy compound method of a kind of synthetic non-chemically, but the research of this respect at home and abroad still is not reported at present.

Summary of the invention

The purpose of this invention is to provide a kind of synthetic method non-chemically of utilizing rapeseed oil, turps to prepare biofuel.

Designed a kind of biofuel according to above-mentioned purpose, its component comprises rapeseed oil, turps, paraffinic hydrocarbons and additive ferrocene.Wherein, the weight percent of each component is respectively rapeseed oil 60～85, turps 10～30, paraffinic hydrocarbons 4～10, ferrocene 0.2～0.5%.Described paraffinic hydrocarbons is meant C ₁₂～C ₁₈Paraffinic hydrocarbons.

Making method of bio-diesel oil according to above-mentioned component is, rapeseed oil, turps, paraffinic hydrocarbons and additive ferrocene are added in the stirring tank in proportion, mixes at normal temperatures and pressures 10～50 minutes, leaves standstill 1 hour after-filtration promptly.

Component raw material sources of the present invention are wide, and main component rapeseed oil, turps are natural reproducible resource, environmental protection; Its production technique operation is simple, reliable, constant product quality; According to the national standard to the petrochemical industry Pyrolysis gas oil PGO biofuel according to gained of the present invention is detected, relevant index reaches prescribed value fully, and wherein calorific value reaches 44.3 (MJ/kg) and is higher than the mean value of foreign biomolecule diesel oil 36 and the mean value of petrifaction diesel 44; Biofuel to the present invention preparation is carried out the engine test in place as can be known, start fast, dynamic performance is good, it is strong to operate steadily, it is atomic that venting port does not almost have the pollutent of black smoke and discharge.

Specific embodiments

When adopting component formulated product of the present invention, be with an amount of rapeseed oil, turps, C ₁₂～C ₁₈After leaving standstill certain hour after raw material stirring such as paraffinic hydrocarbons and additive ferrocene mix, filter, can use.Wherein, rapeseed oil is by directly squeezing in the Semen Brassicae campestris; turps is then taken from natural or tame pine tree; thus Semen Brassicae campestris and terebinthine demand are driven the development of plant husbandry and the greening of hill to a certain extent, not only improved local peasant's income but also conservation of nature ecology has been played pushing effect.

Below be indefiniteness embodiment of the present invention: get and account for the heavy rape oil seed of gross weight 60%, 30% turps, 9.7% C ₁₂～C ₁₈Paraffinic hydrocarbons and 0.3% additive ferrocene, mix mutually stir half an hour after, filter, can carry out can and sale.

Test shows, when the content of rapeseed oil account for gross weight 60～85%, turps accounts for 10～30%, C ₁₂～C ₁₈Paraffinic hydrocarbons account for 4～10% and the additive ferrocene accounted for its result of use and detect almost indistinction of data at 0.2～0.5% o'clock.Wherein, the main effect of each component is that rapeseed oil is the fuel main body, but because rapeseed oil viscosity height needs to add the requirement that suitable thinner could satisfy on-board engine, can satisfy described condition by repeated screening turps, and C ₁₂～C ₁₈Paraffinic hydrocarbons plays action of evocating, and the effect of additive ferrocene is, combustion-supporting, smoke elimination, energy-conservation during aforementioned each component mixing afterfire.Because various places or the different viscosity of rapeseed oil of squeezing under the condition are different, therefore can regulate viscosity or mobile unanimity by terebinthine number.

The biofuel of gained can directly be used according to the present invention, also can mix in the petrifaction diesel and use.
