Description
Technical field
The invention belongs to oil chemical technology field.
Background technology
Sewer oil belongs to the reject product of catering industry, face is wide in a large number, there is no at present good utilization of waste material channel both at home and abroad, causes a large amount of physical obsolescences that produce sewer oil, cause serious environmental pollution, some illegal retailers, serve dining table using the sewer oil of production as edible oil, or as the various food of edible oil raw material production, bring very major injury to people's health, how digestion process sewer oil, turns waste into wealth, and has formed serious social concern.
Fatty acid zinc softening agent is for the industrial chemicals of rubber tyre industry, and the conventional raw material that obtains fatty acid zinc softening agent at present is both at home and abroad plam oil, and the plam oil of take is first produced thick acid as raw material, then reacts with zinc oxide by distil process.Its production technique comprises: hydrolysis, distillation, synthetic, obtain fatty acid zinc rubber plastizing agent, other byproducts of glycerine.This production technique is owing to lacking oil treatment in early stage and granulation process step, can not meet and take the fatty acid zinc rubber plastizing agent needs that sewer oil is raw material production, and because main raw material plam oil acquisition price is far above sewer oil, directly import lipid acid price is higher, and need a large amount of foreign exchanges, the corresponding production cost that raises fatty acid zinc softening agent product.
Summary of the invention
The object of this invention is to provide a kind of method of utilizing sewer oil to produce fatty acid zinc rubber plastizing agent, to solve prior art, lack processing in early stage and rear granulation process step, can not meet and take the needs of sewer oil as raw material production fatty acid zinc rubber plastizing agent, and because main raw material plam oil acquisition price is far above sewer oil, directly import lipid acid price is higher, need a large amount of foreign exchanges, the corresponding problems such as production cost that improve fatty acid zinc rubber plastizing agent product.
The technical solution adopted for the present invention to solve the technical problems is that employing sewer oil is that main raw material is for the feature of sewer oil material composition complexity, increase and process and rear granulation process step early stage, improve distillation and synthesis technique step, obtain highly purified fatty acid zinc rubber plastizing agent and crude acid, other byproducts of glycerine; Its production method processing step is as follows:
1, oil treatment in early stage:
A, freezing: in freezing container, sewer oil raw material is carried out to freezing treatment, 5 ℃ of freezing temperature degree – are to 15 ℃ of –, 2 to 3 hours time;
B, filtration: the sewer oil raw material of freezing treatment is filtered, obtain crystalline product A and non crystallized product B;
2, hydrolysis:
The A that step 1 is obtained, B product adopt mechanical water solution to be hydrolyzed, and are hydrolyzed pressure 2.0 to 2.5Mpa, 220 to 250 ℃ of hydrolysis temperatures; 8 to 10 hours time; A, corresponding thick sour C, the D that becomes correspondence of B product after hydrolysis.
3, distillation:
Thick sour C or D that step 2 is obtained are placed in still kettle vacuum distillation, 220 to 240 ℃ of temperature, and negative-pressure vacuum degree and temperature are negative correlation.
4, rough segmentation:
The product of step 3 is carried out in separation column to rough segmentation, 230 ℃ to 240 ℃ of temperature: pressure 0.995 to 0.0998Mpa fractionates out different distillation stages according to molecular size range stroke, extracts each distillation stage, obtain the thick product of lipid acid that 65% above purity is different.
5, synthetic:
The lipid acid that step 4 is obtained and zinc oxide are synthetic in reactor, adopt the vitriol oil to make catalyzer, proportioning raw materials: lipid acid 85 to 90%, zinc oxide 10 to 15%, catalyzer 0.3 to 0.5%; In reactor, temperature rises to 180 to 200 ℃, is sequentially added into lipid acid, zinc oxide and catalyzer, obtains fatty acid zinc rubber plasticizing agent composition.
6, granulation:
Step 5 is obtained to the granulation in nodulizer of fatty acid zinc rubber plasticizing agent composition, obtain particulate state fatty acid zinc rubber plastizing agent product.
Adopting positively effect of the present invention is these affluent resources of waste sewer oil that take full advantage of catering industry, turns waste into wealth, and has solved the social effects of pollution problem that sewer oil is put on the dining table, and has avoided the discarded environmental pollution bringing of sewer oil.By improvement innovate, experimental study, formed and take sewer oil as raw material, the process matched therewith method of producing, its quality and purity are better than or are equivalent to take the fatty acid zinc rubber plastizing agent product that plam oil or import stearic acid go out as raw material production, raw materials cost reduces more than 30%, save a large amount of imported raw material foreign exchanges, reduced production cost, there is wide market outlook and huge society and economic benefit.
