Problems solved by technology

[0002] Waste oil generally refers to all kinds of low-quality oils that exist in daily life, such as recycled cooking oil, repeatedly used frying oil, etc. These oils are often exhausted, which not only causes environmental pollution, but also is a great waste
At present, there are materials that disclose the technology of refining diesel oil through waste oil, and hydrogenation reaction with hydrogen participation is mostly used. This method is carried out under closed high-pressure conditions, and the reaction conditions are harsh. The participation of hydrogen gas is easy to cause combustion or explosion, and the production is safe. Low resistance, the final product is diesel

Embodiment 1

[0020] The specific steps are:

[0021] ①Pretreatment: Heat 160kg of waste oil to boiling, keep it warm for 15 minutes, cool to room temperature, filter to remove impurities, then heat the waste oil after the filter residue to 80°C, slowly add 22.9kg of 25% partial weight under stirring Sodium aluminate solution, keep warm for 2 hours until completely separated, remove the water layer and flocs; then add 90kg of water to the waste oil, heat to 50°C, keep stirring for 15 minutes, stand until completely separated, remove the water layer , to obtain salt-free waste oil, then add 8 kg of anhydrous magnesium sulfate to the salt-free waste oil, let it stand for 2 hours, filter and remove the magnesium sulfate solid to obtain anhydrous waste oil, and finally add 3.2 kg of activated clay to the anhydrous waste oil , heated to 110°C, kept standing for 1 hour, filtered to remove activated clay, and obtained 150.4kg of pretreated waste oil;

Abstract

The invention relates to a method for preparing biological aviation kerosene by using swell-cooked dirty oil. The method comprises the following steps: filtering out slag, desalting, dewatering and decoloring, then conducting fractional distillation, circulating three to five times together with ammonium formate in circulating type microwave reaction equipment under the action of a Pd/Al2O3 catalyst, extracting together with ethyl acetate, then desalting and dewatering, adding into a fractionating tower for fractionating to obtain biological aviation kerosene. The biological aviation kerosene prepared by adopting the method reaches the existing biological aviation kerosene standard, the shortage of biological aviation kerosene can be effectively overcome, the recovered swell-cooked dirty oil can avoid polluting the environment, and the resources can be saved.

Description

technical field [0001] The invention relates to a method for preparing bio-aviation kerosene, in particular to a method for preparing bio-aviation kerosene with waste oil as raw material. Background technique [0002] Waste oil generally refers to all kinds of low-quality oils that exist in daily life, such as recycled cooking oil, repeatedly used frying oil, etc. These oils are often exhausted, which not only causes environmental pollution, but also is a great waste. At present, there are materials that disclose the technology of refining diesel oil through waste oil, and hydrogenation reaction with hydrogen participation is mostly used. This method is carried out under closed high-pressure conditions, and the reaction conditions are harsh. The participation of hydrogen gas is easy to cause combustion or explosion, and the production is safe. Low resistance, the final product is diesel. With the development of the economy, the usage of aviation kerosene is increasing day ...
