Embodiment 1

[0038] A preparation method for a treatment agent for liquefied petroleum gas purification, the specific steps are as follows:

[0039] (1) earlier take manganese nitrate, antimony nitrate and titanium tetrachloride as raw material, make manganese, antimony doped titanium dioxide;

[0040] (2) Then manganese and antimony doped titanium dioxide are modified on the surface by polyethyleneimine to obtain a modified material;

[0041] (3) The modified material is then reacted with epoxidized cellulose to obtain a composite material;

[0042] (4) Add composite material to the modified bentonite premix again, ultrasonically oscillate evenly, polymerize, and dry to obtain the treatment agent;

[0043] Among them, the modified bentonite premix is ​​obtained by using bentonite as a raw material, which is modified by γ-methacryloxypropyltrimethoxysilane first, and then uniformly mixed with acrylamide and water.

[0044] The specific method of step (1) is as follows: first 1kg manganese ...

Abstract

The invention discloses a treatment agent for liquefied petroleum gas purification and a preparation method thereof. First, manganese nitrate, antimony nitrate and titanium tetrachloride are used as raw materials to prepare manganese and antimony doped titanium dioxide; then manganese and antimony are mixed with manganese and antimony. Hetero-titanium dioxide is surface-modified with polyethyleneimine to obtain a modified material; then the modified material is reacted with epoxidized cellulose to obtain a composite material; the composite material is then added to the modified bentonite premix, ultrasonically oscillated uniformly, and polymerized Reaction, drying, and that's it. The treating agent can realize one-step purification of liquefied petroleum gas, has simple process and good purification effect.

Description

technical field [0001] The invention relates to a liquefied petroleum gas purification material, in particular to a treatment agent for liquefied petroleum gas purification and a preparation method thereof. It belongs to the technical field of liquefied petroleum gas. Background technique [0002] The production methods of liquefied petroleum gas mainly include oilfield associated gas or natural gas extraction, and oil refining extraction. In addition to its main components such as propane, propylene and butane, it often contains more impurities, such as H 2 S, COS, CS 2 , mercaptan, sulfide and disulfide, etc., are poisonous and harmful, seriously pollute the environment and damage human health, and can also cause catalyst poisoning, corrosion of equipment, etc. during the production process, which in turn produces more impurities, resulting in the quality of liquefied petroleum gas not meeting the requirements Related standards. [0003] In addition, the moisture in the...
