I Brief introduction
When the vehicles need more and more high-grade and high-quality gasoline and the government requires exhaust pollution reduction of cities and road vehicles for the environmental protection, more high-grade and high-quality gasoline needs to be produced urgently. Gasoline sweetening refinement is an important part of high-quality gasoline producing for the refinery. The gasoline sweetening catalysts are the key in the gasoline refining process. At present, cobalt phthalocyanine and poly cobalt phthalocyanine are the most used sweetening catalysts in the industry. However, cobalt phthalocyanine is superior than poly cobalt phthalocyanine both in performance and in application.
Cobalt phthalocyanine is an efficient oxidation sweetening catalyst to promote Thiol oxidation and lye regeneration and to achieve "M-erox" catalytic sweetening. It is mainly used for oil (gasoline, kerosene, diesel oil, distillate) refining and propylene desulfurization refining, liquefied petroleum gas desulfurization and sweetening of sour water.
Cobalt phthalocyanine is used for petroleum gas desulfurization refining to make the total sulfur of liquefied petroleum gas lower than national standard control indicators. Besides, the operation is easy and the cost is low. It has a good reputation of the vast national customers.
