Problems solved by technology

The weight and deterioration of raw materials, as well as the application of various additives make H in all kinds of dry gas and liquefied gas 2 The continuous increase of S content has caused many refineries to desulfurize even after using alcohol amine desulfurizers (such as: N-methyldiethanolamine, etc.), although H in liquefied gas 2 The S content is less than 1mg / m3, but the total sulfur content is still high, and the product quality is still unqualified after desulfurization

Embodiment 1

[0011] Take clinoptilolite and heat it to 150-180°C for 1-2 hours, add sodium hydroxide to mix and stir at the same time, continue to heat up to 400°C and continue roasting for 4-8 hours, after the roasting is completed, it will cool down to room temperature, and the above-mentioned zeolite Immerse the reactor with the quaternary ammonium sulfonated cobalt phthalocyanine solution for 30-40 minutes, and then heat the reactor at 110-120°C for 20-30 minutes.

Embodiment 2

[0013] Take mordenite and heat it to 150-180°C for 1-2 hours, add calcium hydroxide to mix and stir at the same time, continue to heat up to 600°C and continue to bake for 4-8 hours. Immerse the reactor containing the quaternary ammonium sulfonated cobalt phthalocyanine solution for 30-40 minutes, and then heat the reactor at 110-120°C for 20-30 minutes.

Embodiment 3

[0015] Take the analcime and heat it to 150-180°C and keep it for 1-2 hours, add sodium hydroxide to mix and stir at the same time, continue to heat up to 400°C and continue to bake for 4-8 hours. Immerse the reactor containing the quaternary ammonium sulfonated cobalt phthalocyanine solution for 30-40 minutes, and then heat the reactor at 110-120°C for 20-30 minutes.

Abstract

The invention discloses a high-efficient desulfurizing agent for environment-friendly treatment. Zeolite is used as a carrier, and quaternary ammonium sulfonated phthalocyanine cobalt solution is used for dipping. Sulfide in the crude oil is removed through the desulfuration of the quaternary ammonium sulfonated phthalocyanine cobalt. Because the zeolite is the large solid-state particles, the separation is very simple after the desulfuration, and the needed working procedures after the desulfuration of a traditional liquid-state desulfurizing agent, such as the repeated acid picking, washing, dehydration and separation, can be avoided. The used carrier can be recycled, the production cost is further reduced, and the desulfurizing agent is suitable for treating the desulfuration of a large amount of the crude oil.

Description

technical field [0001] The invention belongs to the field of petroleum processing, and in particular relates to a high-efficiency desulfurizer for environmental protection treatment and a preparation method thereof. Background technique [0002] With the rapid development of the national economy, to meet the increasing requirements of the society for environmental protection, to further adapt to and meet the objective needs of improving social ecology and sustainable development of the national economy, so for petroleum and petrochemical enterprises, the requirements for product quality upgrading are constantly increasing. Improvement is not only an objective requirement but also a necessity for enterprise development and enhancement of competitiveness. With the continuous exploitation and processing of fossil-based crude oil and the increasing social demand for petroleum and petrochemical products, the nature of crude oil is increasingly heavy and inferior. . The weight a...
