Abstract

A catalyst for purifying the petroleum features that it contains nanotubes of zinc oxide. An absorption tower using said catalyst is also disclosed. Its advantage is high desulfurizing effect.

Description

【Technical field】 [0001] The invention relates to the application of a nano-zinc oxide tube, in particular to the application of a nano-zinc oxide tube as a catalyst for petroleum purification. 【Background technique】 [0002] The corrosive and harmful substances in liquefied petroleum are mainly sulfur dioxide and other sulfides. Due to the different preparation processes of refineries, the existing forms of sulfides in liquefied petroleum are also relatively complex, and compared with natural gas and other fuels, the sulfide content is higher. High, so it is difficult to remove the sulfide by conventional treatment methods. When the above-mentioned petroleum is used as fuel for automobiles and other equipment, after the sulfides are burned at the engine of automobiles and other equipment, part of them will form sulfur oxides and be released into the atmosphere to pollute the air, while part of them will form sulfur and other residues that will remain in the evaporator , ca...
