Problems solved by technology

[0007] The pretreatment process of cooking waste oil as raw material of bio-jet fuel is not yet mature. Although the existing electric desalination process can remove most of the inorganic chlorine, the removal rate of organic chlorine in the raw material is very low.
Most of the residual chlorine after desalination exists in the form of organic chlorine, which will be decomposed to generate hydrogen chloride in the subsequent hydrogenation process. Due to the generation of water in the hydrogenation process, a strong acidic corrosion environment will be formed in the local low temperature part, causing serious damage to equipment pipelines

Embodiment 1

[0039] Base oil preparation: The base oil is obtained after three consecutive desalination and dehydration of the raw material of waste catering oil. The base oil test can fully eliminate the influence of inorganic chlorine, and verify the test effect more conveniently and quickly.

[0040] Pre-desalination and dehydration test conditions: temperature 90°C, electric field strength 1300V / cm, water injection 12wt%, shaking 200 times, residence time 30min. There are three stages of pre-desalting, and the pre-desalting conditions of each stage are the same.

[0041] Considering that the content of inorganic chlorine in the base oil is very low, it is assumed that all the residual chlorine is organic chlorine, and the total chlorine m is analyzed and detected. 0 is 17ppm. After the dechlorination reaction and electro-stripping, the upper oil sample and the lower water sample were taken for salt and water analysis, and the upper oil sample was taken for total chlorine analysis. Co...

Embodiment 2

[0062] Use benzyltrimethylammonium hydroxide as the organochlorine transfer agent B, the base oil used is the same as in Example 1, select a different type of organochlorine transfer agent A, and the auxiliary agent C is compounded with B benzyltrimethylammonium hydroxide , dosage remains unchanged, still 170ppm, agent-to-chlorine ratio (mass ratio)=10: 1, operating procedure is identical with embodiment 1, other technological conditions are constant, investigates different types of organochlorine conversion agent A to dechlorination performance The experimental results are shown in Table 2.

[0063] The proportion of dechlorination agent added to each component is:

[0064] The components of 1# dechlorination agent are: A sodium ethylate 70%wt, B benzyltrimethylammonium hydroxide 20wt%, C glycerin 10%wt;

[0065] 2# dechlorination agent components are: A sodium methoxide 70%wt, B benzyltrimethylammonium hydroxide 20wt%, C glycerol 10%wt;

[0066] 3# dechlorination agent com...

Embodiment 3

[0074] Adopt A (potassium methylate)-B (benzyltrimethylammonium hydroxide)-C (glycerol) as compound system, change the ratio of A, B, operation procedure is the same as embodiment 2, investigate A, B The effect of the ratio on the dechlorination performance, the experimental results are shown in Table 3. Electrodesalination conditions are the same as those in Examples 1 and 2 above. The base oil used is the same as in Example 1.

[0075] The amount of dechlorination agent added is 170ppm, and the ratio of agent to chlorine (mass ratio) is 10: 1, and the proportions of the components of the dechlorination agent added are respectively:

[0076] 1#A Potassium methoxide 70%wt, B benzyltrimethylammonium hydroxide 20%wt, C glycerol 10%wt;

[0077] 2#A Potassium methoxide 65%wt, B benzyltrimethylammonium hydroxide 25%wt, C glycerol 10%wt;

[0078] 3#A Potassium methoxide 60%wt, B benzyltrimethylammonium hydroxide 30%wt, C glycerin 10%wt;

[0079] 4#A Potassium methoxide 55%wt, B ...

Abstract

The invention discloses an organic chloride removing method for waste cooking oil. The organic chloride removing method aims at eliminating the harm of organic chloride to subsequent processing equipment and comprises the steps that at least one stage of electric desalting is conducted on the waste cooking oil; then 6-15% by weight of water is added into the waste cooking oil subjected to electric desalting to be mixed with the oil, and a dechlorination agent is added to perform dechlorination reaction, wherein the dechlorination reaction conditions are described as: the reaction temperature is 90-150 DEG C, the reaction time is 45-120 minutes, the stirring rate is 100-600 r / min, and the agent-chlorine mass ratio is 2-20:1 generally; a reaction product obtained after dechlorination reaction is subjected to electric desalting again to obtain organic chlorine removed cooking oil. The organic chloride in waste cooking oil can be efficiently removed by using the method at low cost.

Description

technical field [0001] The invention belongs to the pretreatment process of meal waste oil (commonly known as "gutter oil"), and in particular relates to a method for removing organic chlorine from meal waste oil as raw material oil of biological jet fuel. Background technique [0002] Under the background of gradually declining fossil fuel reserves and increasingly severe environmental protection, biofuel is a new type of energy that can replace petrochemical energy, and its research and application have attracted more and more attention. [0003] Bio-jet fuel is aviation kerosene produced from renewable resources. Compared with traditional petroleum-based aviation kerosene, bio-jet fuel can reduce carbon dioxide emissions by more than 55%, and is renewable, sustainable, and environmentally friendly. Advantage. Foreign bio-jet fuel technology started earlier and developed rapidly. Major countries in Europe and the United States have successively carried out R&D and testing...
