Embodiment
The present invention has adopted the Principles of Chemical Engineering such as oil extraction and esterification/transesterify, high efficiente callback grease and be processed into the Technology of biofuel from useless carclazyte.
The flow process of production technique of the present invention is referring to Fig. 1.
Using carclazyte in the oil and fat refining process is for grease-decolor, has mainly utilized physical adsorption and two processes of chemisorption of carclazyte, except the colors in the degrease, soap-like matter and the subsidiary impurity such as phosphatide, metal species derivative of removing.Carclazyte is inhaled in these impurity of absorption, has also adsorbed inevitably a large amount of greases, has reduced the yield of grease.
The main chemical constitution of useless carclazyte after the decolouring is: SiO
2, Al
2O
3, Fe
2O
3, CaO, MgO, Na
2O, K
2O, neutral grease, nonhydratable phosphatide, natural pigment, lipid acid and VITAMIN etc. are generally chocolate oil-containing and other organic semi-solid thing, porous surface, and specific surface area can reach 150～459m
2/ g, surface adsorption aromatic hydrocarbons or other oil product have certain combustibility.Because production technique is different with equipment quality, the oil length in the useless carclazyte is also different, generally can reach 20%～30%, and oil refining plant need to be paid cleaning up cost mostly for this reason.
Extraction refiltered oil technique:
Solvent extration is lixiviation process, and the solvent of selecting has methyl alcohol, ethanol, No. 4 solvents (propane and butane) and No. 6 solvents (industrial hexane), wherein No. 6 solvent the bests.
The ratio of useless carclazyte and solvent affects the extraction yield of grease, and ratio is less, and extraction yield is higher.Consider production cost, this project has been selected useless carclazyte: solvent is 1:1 and two kinds of ratios of 1:2 according to weight percent.
Experimental technique: take by weighing useless carclazyte and industrial hexane by different ratios, stir into homogeneous system, the static immersion of normal temperature renews bright solvent and continues to soak after 1 hour, and useless carclazyte is taken out in continuous extraction three times, measures oleaginousness.The oil length of useless carclazyte is 26.55% in this test, and the result is as shown in table 1:
Table 1, the resid amount of useless carclazyte after the industrial hexane extraction
| Sample | Useless in soil (gram) | Industrial hexane (gram) | Extraction time (time) | Resid amount (%) | Percentage extraction (%) |

| 1 # | 100 | 200 | 0.5 | 7.12 | 70.25 |
| 2 # | 100 | 200 | 1.0 | 6.29 | 73.73 |
| 3 # | 100 | 200 | 1.5 | 6.10 | 74.51 |
| 4 # | 100 | 200 | 2.0 | 5.27 | 77.99 |
As shown in Table 3, when extraction time was 2 hours for the second time, the oil mass of extraction was maximum, and residual oil content is minimum, so the Best Times of extraction is 2 hours for the second time.
Get soak time and be 2 hours sample, extract for the third time, extraction time was respectively 0.5,1,1.5,2 hour for the third time.Take out useless carclazyte, carry out residual oil content and measure, calculate the extraction oil mass, the result is as shown in table 4:
