Abstract
The invention discloses a preparation method of an absorptive decolorant special for rapeseed oil refining. The decolorant is prepared by adding carbonized rice husk ash accounting for 2-3% by mass of modified attapulgite into the modified attapulgite and mixing. The preparation method comprises the following steps: (1) purification and activation of attapulgite; (2) modification of attapulgite; (3) preparation of the carbonized rice husk ash; and (4)mixing the modified attapulgite and the carbonized rice husk ash with a mass ratio of 97-98:2-3 in a stirring tank, and smashing by a flour mill to obtain the absorptive decolorant. The prepared absorptive decolorant is large in absorption capacity, high in selectivity, and helps to effectively solve the problem that red chroman-5-quinone and red chroman-6-quinone in rapeseed oil are difficult to decolor.
Description
Technical field
The present invention relates to the preparation method of adsorbent, be specifically related to the preparation method of the special-purpose adsorption decolouriser of a kind of rapeseed oil refining.
Background technology
Rapeseed oil is one of large oil plant of China, and output is only second to soybean, and output in recent years is about 100000t.The amino acid of vegetable seed protein forms and is better than soybean protein, its sulfur amino acid content is higher than soybean protein, and the balance of essential amino acid is also good than soybean protein, more near the recommendation of the United Nations's grain and oil tissue and the World Health Organization (FAO/WHO), the nutritive value of rapeseed protein is parity with or superiority over animal protein, is a kind of very promising full price albumen extremely leaved for development.In view of above-mentioned advantage, rapeseed cultivation is promoted rapidly in China.
Why with color and luster, be that the existence of pigment not only is an impediment to the processing of oil product, also affects the outward appearance of oil product, and finally affects the stability of oil product owing to be mixed with due to the oil-soluble pigment in the various natural oils.In order to guarantee the quality of oil product, satisfy different oil product purposes to the requirement of color and luster, must be to the processing of decolouring of thick oil.
The method of decolouring is a lot, but industrial what be most widely used is adsorption decoloring method.It is to utilize some that pigment is had the material of selectively acting as adsorbent, absorption is except pigment in the degrease and other impurity, thereby improve the oil product presentation quality, can also adsorb simultaneously and remove trace meter and the colloids such as micro-soap, phosphatide, even can also adsorb some stink substance, polycyclic aromatic hydrocarbon and remains of pesticide etc.Thereby guarantee the quality of oil product, be conducive to the oil product deep processing, and improve local flavor and the antioxygenic property of oil product.
In adsorption bleaching, the factor that affects adsorption effect is a lot.Wherein adsorbent is to affect the most key factor of adsorption bleaching effect.Different types of adsorbent has different characteristics, and according to the specific requirement of grease-decolor, the type of choose reasonable adsorbent could obtain best decolorizing effect.
Summary of the invention
The object of the invention is to: the preparation method of the special-purpose adsorption decolouriser of a kind of rapeseed oil refining is provided, and the adsorbent adsorption capacity that adopts this preparation method to obtain is large, and selective wide, adsorption efficiency is high, and production cost is low.
Technical solution of the present invention is: the 2-3% interpolation charring rice husk ash according to its quality in attapulgite modified is mixed into adsorption decolouriser; This preparation method may further comprise the steps:
(1) attapulgite is purified and activated: at first Concave-convex clay rod is added on the wet recessed soil that stirs in the distilled water to get according to mass ratio 6:3, presses mass volume ratio 1:3 in the wet recessed soil and adds mass concentration 4% sulfuric acid immersion 1.5h, gets attapulgite solution; Secondly mass concentration is that 25% sodium hexametaphosphate solution adds in the attapulgite solution according to volume ratio 3:1, and it is 6.5 that mass concentration 1% sodium hydroxide solution is adjusted pH value, supersonic oscillations 2.5h; Then the failure of oscillations, sedimentation separates the deposition impurity layer and gets suspension, and suspension press filtration in filter press gets the attapulgite of moisture content 30%; Then 150 ℃ of dry 3.5h of temperature get the purifying attapulgite in drying box; 350-500 ℃ of roasting 1-3h of final purification attapulgite temperature gets the activation attapulgite;
(2) attapulgite modified: as to add in the high-speed mixer after will activating the attapulgite corase grind, under the 2000r/min high-speed stirred, add the modifier bromination palmityl pyridine of activation attapulgite quality 1.5%, get attapulgite modified;
(3) preparation of charring rice husk ash: rice husk is 350-450 ℃ of heating 3-5h in molten flame stove, cools off to get the charring rice husk ash;
(4) preparation of decolorizer: attapulgite modifiedly mix in agitator tank with the charring rice husk ash according to mass ratio 97-98:2-3, the flour mill abrasive dust gets adsorption decolouriser.
The present invention has the following advantages:
(1) with organic surface active agent bromohexadecane yl pyridines to the attapulgite modifying surface, replace inorganic cation between attapulgite with long carbochain organic cation, interlamellar spacing is enlarged, simultaneously the attapulgite particle surface also can the absorbed portion inorganic cation, the lattice internal and external parts crystallization water, adsorbed water are replaced by organic matter, thereby improve hydrophobicity, strengthen the ability of adsorb organic compound, the attapulgite percent of decolourization after the modification improves greatly;
(2) the charring rice husk ash removes grease deep oxidation product aldehyde compound, charring rice husk ash with attapulgite modified to combine result of use better, the strong characteristics of pigment ability in the attapulgite adsorbed oil had so both been utilized, utilized again the stronger adsorption capacity of charring rice husk ash to residual phosphatide, peroxide, aldehyde compound, free fatty, thereby the color (especially red chroman-5 ,-6 quinones) of rapeseed oil has been played desirable decolorizing effect;
(3) raw material is easy to get, and technique is simple, and is with low cost.
