Description
Technical field
The present invention relates to a kind of preparation method of biofuel, relate in particular to a kind of sewer oil and methyl alcohol of utilizing and prepare method of bio-diesel oil, belong to field of grease chemical technology.
Background technology
The oil product anxiety is nothing to be surprised at, and not only in China, it relates to All Around The World, has employed the deposit oil sources now as the U.S..Oil is a kind of Nonrenewable resources, and prospective oil is limited, and local war happens occasionally in addition, the attack of terrorism, and partial area all make former nervous oil supply make the matter worse with the turmoil of country.The international petroleum price has broken through 70 dollars/barrel at present, and to industrial production, the people's daily life causes very big harm.China has become the second-biggest-in-the-world oil consuming countries that is only second to the U.S. from 2003, for guaranteeing China's economic stability high speed development, realize Chinese nation's development, energy security is the task of top priority, the most important thing, therefore, save energy, the development and use new forms of energy are to solve the energy-intensive effective way.Utilize vegetables oil, it is desirable preparing biofuel as soybean oil, rapeseed oil, Oleum Gossypii semen, Trisun Oil R 80, palm wet goods, and existing people is engaged in the work of this respect.Its problem is to contend over raw materials with edible oil, must not be that cost solves the energy shortage problem with the interests of sacrificing common people.These cost of material height in addition, the biofuel cost of preparing is also high, exceeds commercially available diesel-fuel price.Although the strategic importance of a kind of new forms of energy of exploitation is arranged, is difficult to enter oil product market.For solving above-mentioned two problems, the present invention is the feedstock production biofuel with sewer oil and methyl alcohol, neither strives with edible oil and chews, and price is cheap again, can enter oil product market unobstructedly.Sewer oil is a waste, and price is low.Methanol feedstock is abundant, can be transformed by coal, and China is big coal country, and resource is guaranteed.The low price 2300-2500 unit/ton of methyl alcohol.The economic rationality of utilizing sewer oil and methyl alcohol to prepare biofuel be it serves to show in present commercially available diesel-fuel price 4700-4900 unit/ton.Sewer oil is the vegetable and animals oils that big hotel, restaurant, huge numbers of families' cooking enter water drain, and its composition is the lipid acid triglyceride.Can not look down upon this sewer oil, the sewer oil in 1 year of general provincial capital has about 2,000 ten thousand tons, and common city also had ten thousand tons of 500-1000 in 1 year.This is populous to China, country with a vast territory is an a considerable number of new forms of energy source.
Each city all has a few peoples to be engaged in the trench oil recovery, and some reclaims sewer oil and flows back to the pedlar there that restaurant and fried fruit etc. are engaged in fried food product again, directly endangers the healthy of people.If it as an engineering, is concentrated sewer oil is reclaimed, makes with extra care, be used to prepare biofuel, both purified emissions, stopped the healthy root of harm people, a kind of new forms of energy of cheapness are provided for society again, benefit the society.
Summary of the invention
The invention provides a kind of sewer oil and methyl alcohol of utilizing and prepare method of bio-diesel oil.
The present invention takes following technical scheme:
The present invention utilizes sewer oil and methyl alcohol to carry out esterification under catalyzer and temperature action, and chemical reactions such as ester handing-over generate fatty acid methyl ester, i.e. biofuel.Preparation process is as follows:
1, sewer oil is refining
Sewer oil impurity is many, and step such as removal of impurities, dehydration is refining after filtration.
It is to carry out under 10-50 ℃ of condition that a, sewer oil filter.
Sewer oil after b, the filtration is being to carry out the normal pressure dehydration under the 105-120 ℃ of condition, or at the 750mm mercury column, 50-100 ℃ of condition vacuum hydro-extraction.
C, obtain refining sewer oil by adding that atlapulgite decolours and further purifying.The weight ratio of atlapulgite and sewer oil is 2-6: 100.
2, utilize refining sewer oil and methyl alcohol under complex acid catalyst and temperature action, to carry out esterification and transesterification reaction, obtain fatty acid methyl ester-biofuel.The physical and chemical index of biofuel is similar to diesel oil, and the burning blowdown reduces greatly, is the clean fuel of environmental protection and energy saving.
It is 100 that described sewer oil and methyl alcohol carry out the esterification parts by weight: 13-40,5-10 hour widely different stream reaction times.
Described complex acid catalyst is sulfuric acid and Phenylsulfonic acid, with refining sewer oil weight ratio be 0.5-3: 100.
