Abstract

The invention relates to a compound sulfur removal agent used for petroleum extraction, crude oil processing, gasoline and diesel sulfur removal. The compound sulfur removal agent is prepared from the following raw materials: diethanol amine, triethanolamine, ethanediamine, N,N-=methylethanolamine, ammonia water, diisopropylamine, N,N dimethyl-1,3-propane diamine, cyclo-aziridine and hexadecyl trimethyl ammonium chloride. The invention discloses a preparation method and a using method of the compound sulfur removal agent. The performance of the compound sulfur removal agent is obviously superior to that of an existing conventional sulfur removal agent, the compound sulfur removal agent is high in adaptability and is particularly used for a crude oil extraction and processing process, and the sulfur removal effect can be improved.

Description

technical field [0001] The invention relates to the technical field of oil exploitation, crude oil processing, and gasoline and diesel desulfurization, and in particular to a compound desulfurizer and its preparation method and use method. Background technique [0002] At present, the desulfurizers used in the process of oil exploitation, crude oil processing, and gasoline and diesel treatment have poor adaptability and cannot meet the purpose of desulfurization in oil field development, crude oil processing, gasoline and diesel treatment, especially the deep processing of crude oil and the sulfur content of gasoline and diesel products. development requirements. Contents of the invention [0003] The invention provides a compound desulfurizer and its preparation method and use method, which overcomes the shortcomings of the prior art, and its performance is obviously better than that of the existing conventional desulfurizers. [0004] A composite desulfurizer, which con...
