60 DEG C of the industrial brine that concentration is 20% is added, is stirred and stands, from reactor bottom recovered brine；
The sodium hydroxide solution of concentration 20% is added, is stirred and adjusts pH value to be 8-9, completely reacted material and methanol, aqueous phase is immiscible, pH value is modulated to obtain the mixture that methanol, water, oil are transparent after neutrality.
It is preferred that, methods described also includes：
The gutter oil is put into after reactor, and gutter oil is sloughed into stink under agitation, and is cooled to after moisture is sloughed 50 DEG C；
In the reactor after enriching sulfuric acid, 3 hours are reacted under agitation, 3 hours are stood, then reclaim sulfuric acid aqueous mixtures from reactor bottom；
The concentration that adds is stirred for 20% 60 DEG C of industrial brine and after standing is 1 hour of stirring, stands 1 hour, then from reactor bottom recovered brine.
From such scheme it can be seen that, the present invention takes full advantage of the gutter oil that people discard, modified grease and methanol, dimethyl ether etc. is made by sulfating reaction in gutter oil to dissolve each other, fuel combination as alcohol ether oil, the calorific value of increase fuel combination is reached, methanol, dimethyl ether fuel is solved and there is the defect that calorific value is low, consumption is big, while fuel value is improved, the cost of fuel is reduced again, it is often more important that reach the effect of energy-conserving and environment-protective and twice laid.
Brief description of the drawings
In order to illustrate more clearly about the embodiment of the present invention or technical scheme of the prior art, the required accompanying drawing used in embodiment or description of the prior art will be briefly described below, apparently, drawings in the following description are only some embodiments of the present invention, for those of ordinary skill in the art, on the premise of not paying creative work, other accompanying drawings can also be obtained according to these accompanying drawings.
Below in conjunction with accompanying drawing, the present invention will be further described, in accompanying drawing：
Fig. 1 is methanol fuel gain of heat agent preparation method the first schematic diagram of flow；
Fig. 2 is methanol fuel gain of heat agent preparation method the second schematic diagram of flow.
Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.Based on the embodiment in the present invention, all other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made belongs to the scope of protection of the invention.
Present invention offer is a kind of both to have excellent fuel performance, and the method that utilization gutter oil convenient for cleaning and with low cost prepares methanol fuel gain of heat agent.
Fig. 1 is methanol fuel gain of heat agent preparation method the first schematic diagram of flow, including：
Step 101, using gutter oil, the concentrated sulfuric acid, Nacl, sodium hydroxide be used as raw material carry out hybrid reaction obtain product；
Step 102, it regard the product as methanol fuel gain of heat agent.
Fig. 2 is methanol fuel gain of heat agent preparation method the second schematic diagram of flow.Fig. 2 the inventive method with respect to Fig. 1 more detailed descriptions.
What methanol fuel gain of heat agent of the present invention was mainly made up of following raw material：Discarded gutter oil 100%, the concentrated sulfuric acid 20%, Nacl（Concentration 20%, weight can be the 10%-100% of gutter oil）, sodium hydroxide（Concentration 20%, weight can be the 10%-100% of gutter oil）In right amount（It is appropriate to adjust product pH value 6-9）.
As shown in Fig. 2 its preparation method of the methanol fuel gain of heat agent of the present invention is：
Step 201, first gutter oil is heated with steam, filtering is gone after the removal of impurity, is put into reactor, then be passed through steam, under agitation sloughs gutter oil after stink, is passed through steam heating and sloughs 50 DEG C are cooled to after moisture.
Step 202, under agitation, the concentrated sulfuric acid is added dropwise in reactor, concentrated sulfuric acid weight is between the 20% of trench weight of oil, 60-70 DEG C of reaction temperature of holding, after dripping off, 3 hours of stirring reaction, 3 hours are stood, 20% sulfuric acid aqueous mixtures are weighed from reactor bottom oil recovery.
Step 203,60 DEG C of industrial brines of concentration 20% are added, after 1 hour of stirring, 1 hour are stood, from reactor bottom recovered brine.
Step 204, add the sodium hydroxide solution that concentration is 20%, stir 1 hour, pH value 8-9 is adjusted, completely reacted material and methanol or aqueous phase is immiscible, material and methanol, water, infinitely mix, PH is adjusted to neutrality, as clean methanol, water, oil mixture, you can the gain of heat agent as clean methanol fuel, Industrial Boiler fuel or food and drink cooking fuel are used as.
The principle of the above-mentioned preparation method of the present invention is, discarded food and drink gutter oil is the mixture of animal and plant fat, have the advantages that heat height, cost are low, due to trench, oil does not dissolve in water and methanol, it is generally used for aliphatic acid Methanol-biodiesel ＆ Its processed, because gutter oil is that compound lard still suffers from the defects such as viscosity height, condensation point height in fatty acid methyl ester biodiesel processed, therefore biodiesel is confined as alternative ore diesel oil, it is single also to be used as fuel oil because environmental protection index is exceeded by limitation, therefore widen the application exactly people of gutter oil and expected.
Gutter oil is made modified grease and methanol, dimethyl ether etc. by sulfating reaction and dissolved each other by the present invention, fuel combination as alcohol ether oil, reach the calorific value of increase fuel combination, solve methanol, dimethyl ether fuel and there is the defect that calorific value is low, consumption is big, while fuel value is improved, the cost of fuel is reduced again, it is often more important that reach the effect of energy-conserving and environment-protective and twice laid.Methanol is in burning because calorific value is low, efficiency of combustion is low, add after gain of heat agent, while efficiency of combustion is enhanced, methanol further decomposes CO, H2 and adds the chemical energy of fuel to discharge more energy at high temperature, therefore the caloric value of methanol has been significantly increased, >=33000KJ/kg actual heat is reached.
Therefore methanol fuel gain of heat agent of the present invention, with cost is low, raw material sources are extensive, fuel value is high, to make storage convenient, and when burning, standard limit of smog release is the same with natural gas, is conducive to energy-conserving and environment-protective.
The technical scheme provided above the embodiment of the present invention, it is described in detail, specific case used herein is set forth to the principle and embodiment of the present invention, and the explanation of above example is only intended to help to understand method and its core concept of the invention；Simultaneously for those of ordinary skill in the art, according to the thought of the present invention, it will change in specific embodiments and applications, in summary, this specification content should not be construed as limiting the invention.
