Problems solved by technology

The literature reports on the reduction of adsorbent residual oil mainly focus on solvent extraction method, pressing method, aqueous method, lye extraction method, surfactant method, etc. Solvent extraction method is used to reduce and fill the adsorbent residual oil, and it is necessary to increase the solvent extraction tank and Solvent recovery tanks, etc. require a large investment in equipment, and the involvement of solvents has operational risks; the squeezing method can also be used to reduce residual oil on existing equipment, that is, nitrogen pressure can be increased on existing column equipment to squeeze, but the residual oil The oil reduction effect is not obvious, and the gas pressure is high, and the risk of industrial operation increases; the water method, alkali extraction method, etc. can reduce the residual oil of the filled adsorbent, but both need to increase equipment investment, which will undoubtedly further increase the cost of medicine. oil production cost

Embodiment 1-8

[0178] Pack the column according to the adsorbent scheme in Table 1 to obtain the chromatographic column of Examples 1-8.

[0179] The column chromatography of Examples 1-8 was used to perform column chromatography on 30-fold column volume of soybean oil to purify and prepare high-quality soybean oil, and to determine the weight of the residual oil of the waste filler adsorbent to calculate the residual oil rate of the waste filler adsorbent.

[0180] After the purification process, configure the mobile phase according to the scheme in Table 1, and switch to a new mobile phase, make the aqueous mobile phase pass through the adsorbent column at a certain flow rate (specifically as shown in Table 1), and collect the discharged soybean oil until it is seen The aqueous mobile phase was discharged, the addition of the aqueous mobile phase was stopped, and the final residual oil rate was measured. At the same time, the anisidine value, acid value, peroxide value, color and absorbance of t...

Embodiment 9-14

[0201] Using rapeseed oil, palm oil, corn oil, rice oil, fish oil, and algae oil instead of soybean oil, respectively, column chromatography was performed according to the method of Example 1, and the subsequent chromatography column treatment process. The residual oil amount and grease index of the adsorbent before and after treatment were measured.

Embodiment 15-22

[0208] Prepare multiple chromatography columns, and each column is packed according to the scheme in Table 4 to obtain the chromatography column group of Examples 15-22. The connection mode between the chromatography column groups is series (as attached figure 2 As shown), the column set of Examples 15-22 was used to perform column chromatography on 30 times the column volume of soybean oil to purify and prepare high-quality soybean oil, and to determine the residual oil of the waste packed adsorbent of each chromatography column. After the purification process is over, configure the mobile phase according to the scheme in Table 4, and switch to the new mobile phase at 0.56L / h·cm 2 The flow rate through the chromatography column group is collected, the discharged soybean oil is collected until a small amount of new mobile phase is discharged, the addition of new mobile phase is stopped, and the final adsorbent residual oil amount and oil index of each chromatography column are me...

Abstract

The present invention provides a treatment method for a grease adsorbed adsorbent, wherein a water-containing mobile phase is added to the grease adsorbed adsorbent. According to the present invention, on the base of the existing equipment, the residual grease in the adsorbent is reduced, and the post-treatment step is simplified so as to solve the technical problems of high equipment cost and complex post-treatment in the prior art; and after the treatment through the method of the present invention, the index of the grease desorbed from the adsorbent and the quality of the grease treated by the adsorbent are the same, and the residual grease in the treated adsorbent is low.

Description

Technical field [0001] The invention relates to a processing method of a grease adsorbent in the field of grease refining and a product obtained therefrom. Background technique [0002] Natural oil products usually contain a variety of non-triglyceride impurities. These impurities may originate from oils or from the oil preparation process. Studies have found that fat emulsion injections made from soybean oil containing impurities can trigger pyrogen reactions in the body and seriously threaten the lives of patients. At the same time, when oil is refined at high temperature for a long time, polymers such as conjugated dienes, trienes, and linolenic acid isomers will be produced. Refined oils are also easily oxidized, and oils must be refined before they can be used as medical oils. Medicinal oil is a high-quality oil, and its production, filling and storage have strict guarantee measures. [0003] Column chromatography technology is also called column chromatography technology. ...
