Embodiment 1

[0028] After the Jatropha curcas crude oil, which had been filtered to remove insoluble impurities, was heated to 50° C., 0.5% adsorbent and 1% oxalic acid were added by weight of the oil, stirred for 15 minutes, and then filtered, 70 parts of activated carbon in the adsorbent, Its average pore size is 800nm ​​and its specific surface area is 300m 2 / g, 30 parts of magnesium silicate; after heating the filtered Jatropha curcas oil to 70°C, add 5% chelating agent MEA based on the weight of the crude oil, mix well for 40 minutes, remove the chelating agent MEA by centrifugation, vacuum Dehydration and drying to obtain refined oil.

[0029] The obtained refined oil has an unsaponifiable content of 0.19%, a metal ion content of 9 ppm, a phosphorus content of 2.3 ppm, an acid value of 4 mgKOH / g, and a moisture content of 1000 ppm, and the appearance is clear and transparent.

Embodiment 2

[0031] After the conventional Jatropha curcas refined oil that the insoluble impurities were removed by filtration and reached the index through prior art processing was heated to 60°C, 10% adsorbent and 0.8% acetic acid were added by weight of grease, stirred for 45 minutes, and then filtered , 85 parts of activated carbon in the adsorbent, its average pore size is 100nm, and its specific surface area is 500 m 2 / g, 15 parts of magnesium silicate; after heating the filtered conventional Jatropha curcas oil to 80°C, add 3% chelating agent MEA based on the weight of conventional Jatropha curcas oil, mix well for 30 minutes, and remove by centrifugal separation chelating agent MEA, vacuum dehydration and drying to obtain refined oil.

[0032] The obtained refined oil has an unsaponifiable content of 0.2%, a metal ion content of 8.1 ppm, a phosphorus content of 2.2 ppm, an acid value of 2.5 mgKOH / g, and a moisture content of 800 ppm, and the appearance is clear and transparent. ...

Embodiment 3

[0034] After the Jatropha curcas crude oil with the insoluble impurities removed by filtration was heated to 95°C, 5% adsorbent and 0.1% citric acid were added by weight of the oil, stirred for 50 minutes, then filtered, and 80 parts of activated carbon in the adsorbent were added. , with an average pore size of 500 nm and a specific surface area of ​​400 m 2 / g, 20 parts of magnesium silicate; after heating the filtered Jatropha curcas oil to 40°C, add 1.5% chelating agent MEA based on the weight of the crude oil, mix well for 50 minutes, remove the chelating agent MEA by centrifugation, vacuum Dehydration and drying to obtain refined oil.

[0035] The obtained refined oil has an unsaponifiable content of 0.15%, a metal ion content of 5ppm, a phosphorus content of 1.5ppm, an acid value of 2mgKOH / g, and a moisture content of 500ppm. The appearance is clear and transparent.

Abstract

The invention discloses Jatropha bio-aviation fuel refined oil, which is characterized in that in the refined oil, the unsaponifiable matter content is less than or equal to 0.2 percent, the metal ion content is less than or equal to 10 ppm, the phosphorus content is less than or equal to 3 ppm, the acid value is less than 5 ImgKOH / g, the moisture content is less than or equal to 1000 ppm, and the appearance is clear and transparent. The invention further discloses a preparation method of the Jatropha bio-aviation fuel refined oil. Due to the situations that on one hand, the method adopts an acidic modifying agent to convert nonhydratable phospholipid into hydratable phospholipid, and on the other hand, the method selects activated carbon with the aperture matched with the size of phospholipid and larger specific surface area and magnesium silicate, and additionally adopts succimer MEA, the nonhydratable phospholipid and metal ions and the like in Jatropha crude oil or in conventional Jatropha refined oil processed by the prior art can be effectively removed, and various performance indexes of the obtained refined oil achieve the standard for the production of the bio-aviation fuel refined oil, so that the possibility of large-scale production of Jatropha bio-aviation fuel is realized; and the method is simple and mature, has low investment cost, and is particularly suitable for industrial application.

Description

technical field [0001] The invention belongs to the technical field of biological aviation fuel raw material oil and its preparation, and particularly relates to a Jatropha curcas aviation fuel refined oil and a preparation method thereof. Background technique [0002] Jatropha curcas is a perennial drought-tolerant woody plant with strong vitality, suitable for planting in barren and marginal lands without occupying arable land. It has simple planting, extensive management and rapid growth. It can be put into production in 3 years, and it will enter the full fruit period in 5 years. The fruit picking period is as long as 50 years, and the oil content of the seed kernel is 60-70%. Since Jatropha curcas oil is not edible, it has been recognized by the industry as an ideal source of raw materials for the preparation of biodiesel, and it is also recognized as one of the high-quality bio-aviation fuel raw materials at home and abroad. At present, more than 40 countries are plan...
