Problems solved by technology

But this technology has following problems: 1) can produce a large amount of alkali slag, and alkali slag has serious stench smell, can cause environmental problem; Harmful substances exceed the standard); 3) It takes a lot of manpower and material resources to deal with alkali slag, and there is secondary pollution. Discharging sulfur into the atmosphere in the form of oxides will cause air pollution; 4) There are hidden dangers in operation, When mixing lye, caustic soda and lye are easy to hurt people, and when unloading lye residue, it is easy to cause leakage of liquefied petroleum gas

Abstract

The invention relates to an organic sulfur conversion catalyst for liquefied gas and belongs to the technical field of liquefied gas refining. The organic sulfur conversion catalyst for liquefied gas disclosed by the invention comprises the following components in percentage by weight: 10-20 percent of Ni, 5-10 percent of Na2O and the balance of a carrier, wherein the carrier refers to gamma-Al2O3. According to the catalyst disclosed by the invention, the organic sulfur conversion rate in the liquefied gas is high, namely the thiol conversion rate is more than or equal to 95 percent, the carbonyl sulfide conversion rate is more than or equal to 98 percent, and the carbon disulfide conversion rate is more than or equal to 90 percent.

Description

technical field [0001] The invention relates to the technical field of refining liquefied gas in petroleum processing, in particular to a catalyst for converting organic sulfur contained in liquefied gas. Background technique [0002] Liquefied petroleum gas is one of the products in the petroleum processing process, and it is also an important raw material for further processing into other products. Refined raw material liquefied petroleum gas is mainly liquefied gas after desulfurization by alcohol amine method. The main components of liquefied gas from the desulfurization unit by alcohol amine method are C3 and C4 components, containing a small amount of hydrogen sulfide and organic sulfur (mainly mercaptan , carbonyl sulfide, carbon disulfide). [0003] At present, the liquefied gas mercaptan conversion catalysts mainly include sulfonated cobalt phthalocyanine and polyphthalocyanine cobalt catalysts, but these two catalysts only have a good conversion effect on sodium m...
