Technical Field
The invention relates to the technical field of petroleum desulfurization, in particular to a petroleum desulfurization adsorbent.
Background
Petroleum refers to a mixture of hydrocarbons in gaseous, liquid and solid states, with natural occurrence. Petroleum is classified into crude oil, natural gas liquids, natural coke oils, etc., but "petroleum" is still used as the definition of "crude oil" in a conventional manner.
The petroleum contains sulfur-containing waste hydrogen, which is harmful to human body, and the adsorption desulfurization technology attracts more and more attention due to the advantages of low equipment investment, high desulfurization rate, no hydrogen consumption, low price and the like.
Disclosure of Invention
The invention aims to provide the petroleum desulfurization adsorbent which is low in price, convenient to use and environment-friendly.
The above purpose is achieved by the following scheme:
the petroleum desulfurization adsorbent is characterized by being prepared from the following raw materials in parts by weight:
20-40 parts of peanut shell, 10-20 parts of corncob, 5-10 parts of straw, 13-21 parts of polyvinyl alcohol, 13-15 parts of ethylene glycol, 4-5 parts of lime, 30-50 parts of natural zeolite, 1-2 parts of coconut monoethanolamide, 1-3 parts of sodium cobalt hexanitrate and 1-3 parts of guar gum.
The petroleum desulfurization adsorbent is characterized in that: the preparation method comprises the following steps:
(1) crushing natural zeolite, and sieving with a sieve of 100-120 meshes to obtain zeolite powder for later use;
(2) uniformly mixing the zeolite powder with polyvinyl alcohol and ethylene glycol, adding a proper amount of water, and grinding for 3-6h to obtain mixed powder for later use;
(3) uniformly mixing peanut shells, corncobs and straws, adding coconut monoethanolamide, sodium cobalt hexanitrate, guar gum and a proper amount of water, crushing, uniformly stirring, drying, soaking in a potassium permanganate solution for oxidation treatment, and drying to obtain compound powder for later use;
(4) mixing the compound powder with the rest raw materials.
The petroleum desulfurization adsorbent is characterized in that: the concentration of the potassium permanganate solution is 1-2%.
The invention has the beneficial effects that:
(1) the petroleum desulfurization adsorbent prepared by the invention has the advantages of good adsorption performance and strong regeneration capacity.
(2) According to the invention, the desulphurization adsorbent is prepared by modifying peanut shells, corncobs, straws and the like, oxidizing by potassium permanganate and then matching with other raw materials, so that the desulphurization adsorbent is long in service life, environment-friendly, capable of changing waste into valuable and capable of removing sulphur to 1 ppmw; low production cost and suitability for industrial production. Can be widely applied to the removal of sulfur in crude oil and dry gas of refineries, liquefied gas, oil field gas and natural gas.
Detailed Description
The petroleum desulfurization adsorbent is prepared from the following raw materials in parts by weight (kg):
40 parts of peanut shells, 20 parts of corncobs, 10 parts of straws, 21 parts of polyvinyl alcohol, 15 parts of ethylene glycol, 4 parts of lime, 30 parts of natural zeolite, 2 parts of coconut monoethanolamide, 3 parts of sodium cobalt hexanitrate and 3 parts of guar gum.
The preparation method of the petroleum desulfurization adsorbent comprises the following steps:
(1) crushing natural zeolite, and sieving with 100 mesh sieve to obtain zeolite powder;
(2) uniformly mixing the zeolite powder with polyvinyl alcohol and ethylene glycol, adding a proper amount of water, and grinding for 6 hours to obtain mixed powder for later use;
(3) uniformly mixing peanut shells, corncobs and straws, adding coconut monoethanolamide, sodium cobalt hexanitrate, guar gum and a proper amount of water, crushing, uniformly stirring, drying, soaking into a potassium permanganate solution with the concentration of 1% for oxidation treatment, and drying to obtain compound powder for later use;
(4) mixing the compound powder with the rest raw materials.
The modified desulfurization adsorbent prepared by the embodiment has high desulfurization depth, can reduce the sulfur in the raw material gasoline to below 1ppmw within 5-6 hours of adsorption desulfurization, and has a service life as long as about 10 hours.
