The GR-300 catalyst's core advantage lies in its bimodal pore design: its abundant micropores provide a large surface area, creating numerous active sites and ensuring high catalyst reactivity and stability. Simultaneously, a moderate number of macropores act as "highway channels," significantly improving the diffusion efficiency of reactants and products (especially liquid sulfur), effectively eliminating internal diffusion limitations and preventing pore clogging.
◼PRODUCT DESCRIPTION
GR-300catalyst is anAl203-based sulfur recovery catalyst with large specific surface area and large pore volume. Its comprehensive performance has reached the international advanced level. It is suitable for claus sulfur recovery units in the fields of petrochemicals, coal chemical industry, etc. It can be used in the full bed of claus reactors at any stage of the sulfur recovery unit or used in layers with other catalysts of different functions or types.
LS-300catalysthasthefollowingperformancecharacteristics:
(1)Large specific surface area, more active centers, high activity and good activity stability; (2)The catalyst pore structure is abi modal distribution. small pores provide a large specific surface area, active centers and ensure that the catalyst has sufficient mechanical strength. The appropriate amount of large pores reduces the diffusion restriction of process gas inside the catalyst particles, which is conducive to the reactants to reach the active centers more easily;(3)The catalyst has high strength, low abrasion and long service life.
◼What are the specific advantages of the GR-300 catalyst's "bimodal pore structure"?
The bimodal pore structure combines both micropores and macropores: the micropores provide a large surface area, ensuring high catalytic activity; the macropores serve as diffusion channels, improving mass transfer efficiency and preventing sulfur clogging. This structure combines high activity with long life, a combination not possible with conventional catalysts.
◼What is the importance of the catalyst's high mechanical strength in actual operation?
High mechanical strength means the catalyst is resistant to attrition and crushing, which reduces dust generation during operation and prevents increased reactor bed pressure drop, thereby ensuring long-term stable operation and minimizing unplanned downtime.
◼Can the GR-300 catalyst process process gases containing organic sulfur?
As an excellent Claus catalyst, GR-300 has some ability to hydrolyze organic sulfur compounds (such as COS and CS₂). However, for gases with high organic sulfur content, it is recommended to layer the catalyst with a dedicated hydrolysis catalyst for optimal performance.
◼What industrial fields is this catalyst primarily suitable for?
It is primarily used in refinery acid gas treatment, natural gas purification, and desulfurization units in the coal chemical industry.
◼What is the typical service life of the GR-300 catalyst?
Under normal operating conditions, the GR-300 catalyst has a service life of 3-5 years. The specific service life depends on factors such as feed gas composition, operating conditions, and unit stability.
