Description
Technical field
The present invention relates to technical field of biodiesel preparation, and waste oil in kitchen waste is utilized in particular to one kind
The method for producing biodiesel.
Background technology
Biodiesel, also known as fatty acid methyl ester, it is a kind of New-type fuel produced using vegetable oil or animal oil processing.With
The pay attention to day by day of worldwide energy shortage and people to environmental protection, this green of R and D biodiesel
Environment-friendlyfuel fuel is extremely urgent to substitute the petroleum-based energy of continuous exhaustion.Gutter oil based on animal and plant fat is reacted
Modification can turn into the bio-fuel used for internal combustion engine, be the regenerative resource of cleaning, be typical " green energy resource ", energetically
Development biodiesel has to sustainable economic development, propulsion energy substitution, mitigation environmental pressure, control urban atmospheric pollution
Important strategic importance.
In China, the yield of waste cooking oil is very big, it was reported that the only waste cooking oil in Shanghai City, it is annual just more than 150kt.Hair
The catering trade reached is provides the raw material of abundance using kitchen gutter oil preparing biological diesel oil, using cheap kitchen gutter oil as original
The prepared biodiesel of material, its manufacturing expense significantly reduce than the biodiesel using vegetable oil as raw material.In energy today
Source is in short supply, price of oil going up sky-high at the time of, the gas station in city arrange long queue wait diesel oil automobile, it is believed that people for hair
Exhibition biodiesel has sufficient enthusiasm.It is that raw material produces biodiesel using kitchen gutter oil, to preventing kitchen gutter oil again
The secondary development for flowing into dining table and promoting biodiesel has sufficient superiority.
The content of the invention
It is an object of the invention to provide a kind of method that biodiesel is produced using waste oil in kitchen waste, to solve
Above mentioned problem.
To realize the object of the invention, the technical scheme that uses for：One kind produces biological bavin using waste oil in kitchen waste
The method of oil, specifically comprises the following steps：
（1）Kitchen garbage be sent in filter plant and carries out being filtrated to get gutter oil, obtained gutter oil is sent to
Precipitated in sedimentation basin, the gutter oil after precipitation is heated up to 60 DEG C -110 DEG C, and the gutter oil of heating is subjected to vacuum and taken off
Water obtains feedstock oil, and feedstock oil is sent into agitator；
（2）Aluminum sulfate is added into agitator by trench oil purification, the gutter oil in agitator is divided into and separates colloid and impurity；
（3）Caused colloid in step 2 is sent in reactor, reactor is warming up to 70 DEG C -80 DEG C, and into reactor
Methanol is added, stirs 1h-2h；
（4）0.4%-0.6% pyrovinic acid, 0.3%-0.6% phosphate and 3%-5% hydroxide is added into reactor
Sodium, and be uniformly mixed；
（5）Obtained product in step 4 is centrifuged, upper strata is the biodiesel prepared, and lower floor is glycerine, solid
Base catalyst and remaining methanol, lower floor is released, separate solid base catalyst and be distilled to recover methanol.
Further, the whipping temp in the step 4 is 80 DEG C -110 DEG C, mixing time 3h-5h.
Further, it is described that obtained biodiesel in step 4 is heated to 90 DEG C~110 DEG C at ambient pressure, and add
Percentage by weight 3-5% decolorising agent, carry out decoloring reaction.
Further, the decolorising agent is hydrochloric acid, sodium hypochlorite.
The beneficial effects of the invention are as follows,
Raw material of the present invention is easy to get, simple production process, production equipment totally-enclosed, will not cause secondary environmental pollution.The present invention
The resource circulation utilization of waste oil in kitchen waste is efficiently solved, it is achieved thereby that the purpose that kitchen garbage is turned waste into wealth, together
When also improve foodsafety.
Embodiment
The present invention is described in further detail below by specific examples of the implementation.
A kind of method that biodiesel is produced using waste oil in kitchen waste provided by the invention, specifically includes following step
Suddenly：
（1）Kitchen garbage be sent in filter plant and carries out being filtrated to get gutter oil, obtained gutter oil is sent to
Precipitated in sedimentation basin, the gutter oil after precipitation is heated up to 60 DEG C -110 DEG C, and the gutter oil of heating is subjected to vacuum and taken off
Water obtains feedstock oil, and feedstock oil is sent into agitator；
（2）Aluminum sulfate is added into agitator by trench oil purification, the gutter oil in agitator is divided into and separates colloid and impurity；
（3）Caused colloid in step 2 is sent in reactor, reactor is warming up to 70 DEG C -80 DEG C, and into reactor
Methanol is added, stirs 1h-2h；
（4）0.4%-0.6% pyrovinic acid, 0.3%-0.6% phosphate and 3%-5% hydroxide is added into reactor
Sodium, and be uniformly mixed；
