Embodiment 1

[0053] The raw material oil is Chinese tallow tree oil, and its properties are shown in Table 1. By adopting the method provided by the present invention, the palm oil successively passes through the hydrotreating reaction zone, the hydroisomerization depressing zone A zone, the hydroisomerization depressing zone B zone and the hydrofining reaction zone to react to obtain the hydrofining reaction product, wherein, taking Chinese tallow oil as a benchmark, the mass content of water entering the hydrotreating reaction zone is 8%, and in the hydroisomerization depreciation reaction zone, the A zone and the B zone The catalyst loading ratio is 1:1. After the gas-liquid separation of the hydrofining reaction product, its liquid phase flow enters the distillation zone, and jet fuel and solvent oil are obtained after fractional distillation.

[0054] The hydrogenation reaction conditions are shown in Table 2, and the product distribution and properties are shown in Table 3 and Table ...

Embodiment 2

[0056] Jatropha oil is used as raw material oil, and its properties are shown in Table 1. By adopting the method provided by the present invention, waste catering oil is sequentially passed through the hydrotreating reaction zone, hydroisomerization depressing zone A, hydroisomerization depreciation zone B and hydrogenation The reaction is carried out in the refining reaction zone to obtain a hydrofining reaction product. Among them, based on jatropha oil, the mass content of water entering the hydrotreatment reaction zone is 6%, and in the hydroisomerization decondensation reaction zone, the catalyst loading ratio of zone A and zone B is 1:1. After the gas-liquid separation of the hydrofining reaction product, its liquid phase flow enters the distillation zone, and jet fuel and solvent oil are obtained after fractional distillation.

[0057] The hydrogenation reaction conditions are shown in Table 2, and the product distribution and properties are shown in Table 3 and Table 4. ...

Abstract

The invention discloses a method of using renewable raw materials to prepare jet fuel. The method includes: in a hydrotreating reaction area, after being mixed with hydrogen and water, enabling vegetable oil and / or animal fat to contact with a hydrotreating catalyst for reaction to obtain a hydrotreating reaction product; in a hydrogenation isomerization pour point depression reaction area, enabling the hydrotreating reaction product to contact with a hydrogenation isomerization pour point depression catalyst for reaction to obtain a hydrogenation isomerization pour point depression reaction product, wherein a hydrogenation isomerization pour point depression area A and a hydrogenation isomerization pour point depression area B which are in serial connection are arranged in the hydrogenation isomerization pour point depression reaction area; in a hydrogenation refining reaction area, enabling the hydrogenation isomerization pour point depression reaction product to contact with a hydrogenation refining catalyst for reaction to obtain a hydrogenation refining reaction product, and separating and fractionally distilling the hydrogenation refining reaction product to obtain the jet fuel. By adopting the method, the jet fuel is high in yield and low in freezing point.

Description

technical field [0001] The present invention relates to a method of producing jet fuel using a hydrotreating process of renewable raw materials. Background technique [0002] With the tightening of traditional fossil energy supply and increasing pressure to reduce carbon dioxide emissions, the development of renewable and clean alternative energy has become a global consensus. Due to its renewable and green nature, bioenergy has received special attention in recent years and is considered to be one of the most ideal ways to solve the global energy crisis. [0003] As the demand for jet fuel continues to increase, the technology to prepare jet fuel from renewable raw materials is gaining more and more attention. These renewable raw materials include, but are not limited to, vegetable oils (soybean oil, rapeseed oil, palm oil, jatropha oil, tallow oil), animal fats (lard, tallow, fish oil), acidified oils, various fatty acids and acidified oils. [0004] At present, there a...
