What are the types of refined propylene desulfurization agents?
Thread Content
A major overhaul is coming up, and it’s time to replace the propylene desulfurization agent. The JX-4A type was used in the past; are there any other models available? Please recommend some. Thank you
As far as I know, JX-4A is one of the three catalysts used in Beijing Sanju’s liquefied gas desulfurization process; it is not a propylene purification catalyst. Generally, it is not possible to replace just one of these catalysts, unless that particular process is not used! JX-4A low-temperature desulfurizer is a low-temperature desulfurizer whose main active component is a composite metal compound. It can remove hydrogen sulfide and certain organic sulfides from liquefied gas with high precision, ensuring that the liquefied gas meets the requirements for “copper sheet corrosion” testing. It can also remove hydrogen sulfide and other impurities from other refinery gases, naphtha, and other gaseous and liquid materials with high precision, thereby achieving thorough purification of these materials.
The WS321 hydrolysis catalyst is available at www.sdjr-tech.com; the poster can inquire there. We are currently using this catalyst in combination with another one, and the results are very good.
