T503-type (851) at room temperature COS hydrolysis agent

First, Properties and Uses
The activity of the catalyst based on alumina as a carrier can often , a COS hydrolysis catalyst under low temperature , which can be liquid propylene trace COS , CS2 as the hydrolysis of organic sulfur H2S, zinc oxide desulfurization catalyst operated in series , can be achieved desulfurization effect. Further , since the surface of the hydrolyzing agent is very chemisorption , can also remove common poisons and other organic sulfur chloride, cyanide and the like. 1991 won the National Science and Technology Progress Award.

Fourth, industrial application and application prospects
T503 -type zinc oxide at room temperature hydrolysis agent and desulfurization agent can be used in tandem Highland propylene feed to 0.1ppm or less of total sulfur removal . This product has been since the late eighties highland material for domestic Oxo alcohols and propylene desulfurization dozens of sets of large , medium and small polypropylene unit , has a good reputation. The product is due to the low operating temperature , simple operation, desulphurization and energy saving effect is obvious , has brought great economic benefits to the user , it has an extremely wide range of applications .
 
Fifth, packaging and storage
T503 type hydrolysis agent used iron ( lined with plastic ) packaging, 30 kg per barrel . This product must not be in contact with moisture and other chemicals . Prevent the fall roll handling during transportation . Airtight storage for three years does not affect use.
